An Old Face in the Dairy Aisle: A Chance Encounter Nearly Thirty Years in the Making

There is something rather extraordinary about running into someone from your past when you least expect it, particularly when you have reached the point in life where the past feels comfortably tucked away in its own little corner of your memory. You can go years, sometimes decades, without giving a particular person much thought, only to have the universe arrange a chance encounter in the most ordinary of places. Not at a high school reunion, not at a wedding, not through the modern ritual of reconnecting on Facebook, but somewhere as thoroughly mundane as the dairy aisle of a Stop & Shop in Smithfield, Rhode Island, while you are pushing a shopping cart full of groceries after spending most of the night dealing with the finest assortment of medical emergencies that Boston could throw at a trauma surgeon. Life has a peculiar sense of humor that way. It will allow you to spend years navigating operating rooms, intensive care units, and the general business of becoming an adult, only to remind you, at seven o’clock on an ordinary Friday morning, that the people and places of your youth have a way of finding you again.

My morning had begun long before most of Rhode Island had given serious consideration to the prospect of getting out of bed. I had covered an overnight shift at the hospital in Boston as the attending trauma surgeon, and the night had been one of those stretches that makes you appreciate the difference between knowing what you signed up for and actually experiencing it. Trauma surgery is an interesting profession in that regard. You can spend years in medical school, residency, and fellowship learning anatomy, physiology, surgical technique, resuscitation, and the innumerable ways the human body can go catastrophically wrong, but no amount of preparation entirely eliminates the unpredictability of a busy trauma service. Boston has no shortage of ways to keep a trauma surgeon occupied overnight, and this particular shift had provided a fairly comprehensive demonstration of the city’s capabilities. By the time morning arrived, I had spent enough hours dealing with the consequences of other people’s unfortunate circumstances that my own immediate ambitions had become considerably less dramatic. I wanted to get home, eat something decent, see my wife, and perhaps enjoy the satisfaction of completing a grocery run before the rest of the world descended upon the supermarket.

For anyone unfamiliar with my daily commute, getting from the hospital in Boston back to our home in Glocester, Rhode Island, is a fairly straightforward exercise in interstate navigation. I leave Boston, pick up Interstate 93 South, connect with Interstate 95 South, and eventually transition onto Interstate 295 South, which carries me back into Rhode Island. From there, I take Route 44 through Smithfield, and before long I am heading toward the familiar rural roads that eventually bring me home to the homestead. It is a route I know well enough that much of it has become second nature, the familiar succession of highway signs, interchanges, and landmarks that marks the transition from the dense urban environment of Boston to the quieter landscape of northern Rhode Island. After a night in the hospital, that transition is particularly welcome. There is a certain psychological relief in watching the city recede in the rearview mirror, knowing that the immediate demands of the trauma service have been handed over and that the next stretch of road is taking you toward home rather than another resuscitation bay.

That morning, however, I had a small errand to complete before returning to Glocester. I told Sadie that I was going to stop for groceries on the way home because, given the hour, it made considerably more sense to take advantage of the early start than to drive home, settle in, and eventually have to go back out again. We are practical people about these things. There is no particular virtue in making two trips when one will do, especially when one of those trips can be accomplished before the rest of the shopping public has fully awakened. I briefly considered stopping at Dino’s in Chepachet, which would have been a perfectly reasonable option given that it is closer to home and familiar territory, but Stop & Shop in Smithfield was already along my route. There was no reason to complicate the morning, so I continued toward the supermarket with the sort of modest enthusiasm that only someone who has spent an entire night in a hospital can muster for grocery shopping.

I arrived at approximately seven o’clock, just as the doors opened, and I remain convinced that this is one of the finest times of day to shop. The early-morning supermarket occupies a completely different universe from the same building at five o’clock in the afternoon. There are no great traffic jams of shopping carts, no families negotiating the cereal aisle as though they are coordinating an international peace treaty, no shoppers standing directly in front of the item you need while contemplating the philosophical implications of buying organic pasta. The parking lot is quiet, the aisles are relatively empty, and the entire experience feels wonderfully efficient. You can move at your own pace, select what you need, and proceed through the store without having to navigate a human obstacle course. For someone who had spent the night dealing with the urgent needs of critically injured patients, the simplicity of the arrangement was almost therapeutic. Nobody was paging me, nobody needed an operation, and the most pressing decision before me was which groceries needed to make their way into the cart.

I should probably mention that I was not exactly presenting the picture of a man who had enjoyed a restful evening. After a night on the trauma service, my appearance was less polished physician returning from a successful day at the office and more exhausted individual who had recently gone several rounds with the darker elements of human existence and emerged with his dignity intact but his complexion under review. I imagine I had the familiar look of someone who had slept very little, consumed an unreasonable amount of coffee, and spent the better part of the night concentrating on problems that did not permit casual mistakes. My hair probably had its own interpretation of events, my eyes were undoubtedly carrying the accumulated weight of the overnight shift, and my general appearance suggested that the distinction between being awake and merely continuing to function had become somewhat academic. Still, the groceries were getting done, and I was looking forward to heading home.

I was working my way through the store with a full cart when I heard a voice behind me.

“Are you Stephen?”

It was such an ordinary question, delivered in such an ordinary setting, that for a moment I did not immediately appreciate the significance of it. There are not many places where a person expects to be recognized after nearly thirty years, and a supermarket dairy aisle is not generally high on that list. I turned around, looked at the man who had addressed me, and then experienced that peculiar sensation that occurs when a face you have not seen in decades suddenly becomes unmistakable. The hair may have changed, the face may carry the inevitable marks of time, and the years may have rearranged a few things, but somewhere beneath all of that remains the person you remember.

I recognized him.

His name was Steven, and he was the father of Lauren, a girl I dated when I was a student at Ponaganset High School in the 1990s. For a moment, standing there among the milk, half-and-half, yogurt, and various other necessities of modern refrigeration, I was transported backward through nearly three decades of my life. It is difficult to explain how quickly those memories can return. You are standing in the present, wearing the accumulated experience of adulthood, thinking about work, your wife, the drive home, and the groceries you still need to buy, and then someone from your youth appears and suddenly an entirely different version of your life comes into focus. You remember people, places, conversations, and the general atmosphere of a time that seemed perfectly ordinary while you were living through it but has since acquired the peculiar glow of history.

What made the encounter particularly remarkable was not simply that Steven recognized me, but that he remembered me well enough to approach me in the first place. We were talking about a period of life that reaches back to the 1990s, when I was a student at Ponaganset High School and dating his daughter. Nearly thirty years have passed since then. In the intervening years, I went to Harvard, attended medical school, completed surgical training, pursued trauma and critical care, and built a professional life in Boston. I have spent an extraordinary amount of time in hospitals, operating rooms, and intensive care units, and eventually returned to Glocester after nearly two decades in the city. I married Sadie, established a home, and developed an entirely different collection of daily responsibilities. The boy Steven remembered had grown into a physician, a husband, and a man whose ordinary Friday morning might involve driving home from an overnight trauma shift while contemplating whether the refrigerator needed more milk.

And yet, somehow, the connection remained sufficiently intact that he could look at me in a supermarket and ask whether I was Stephen.

There is something quietly flattering about being remembered, particularly when the person doing the remembering belongs to a chapter of your life that you have not visited in a very long time. We spend much of adulthood moving forward, often at a considerable pace, and it is easy to imagine that the people we knew in our youth have gradually faded into the background of their own lives. We assume that the relationships, acquaintances, and family connections that once seemed so familiar have been absorbed into the passage of time. Then, without warning, someone appears who remembers you from a period when your entire world was considerably smaller, when your future was still an open question, and when you had not yet accumulated the experiences that would eventually define your adult life.

Steven was standing there wearing a black-and-white plaid shirt, jeans, and his University of Vermont hat. That hat deserves special mention because I swear I remembered it from my youth. There are certain details about people that lodge themselves in your memory for reasons you cannot entirely explain. It may be a familiar expression, a particular manner of speaking, the way someone laughs, or an article of clothing that seems to have become a permanent part of their identity. In Steven’s case, the University of Vermont hat was apparently one of those enduring details. There it was, nearly thirty years later, as familiar as a landmark on an old road. I could have sworn that I had seen him wearing it back when Lauren and I were dating in high school, and the fact that he was still wearing what appeared to be the same kind of hat made the encounter feel even more surreal.

We began talking right there near the milk and half-and-half, which is perhaps not the most glamorous setting in which to conduct a reunion nearly three decades in the making, but it was entirely appropriate for the way life tends to unfold in small towns. There was no grand announcement, no carefully arranged meeting, and no awkward attempt to manufacture a moment of significance. There were simply two people who had not seen each other in years, standing in a supermarket aisle and catching up as though the intervening decades had been compressed into a surprisingly short conversation.

I told him that I had moved back to Glocester, that I was married, and that I had become a doctor. Saying those things aloud in that setting felt a little like providing a brief summary of an entire adult life to someone who remembered me before any of it had happened. When Steven first knew me, I was a high school student dating his daughter. I had ambitions, certainly, and I had some idea of where I hoped life might take me, but the intervening years contained an enormous amount of uncertainty, work, sacrifice, and change that no teenager could fully appreciate. The path from Ponaganset High School to medical school, surgical residency, and a career as an attending trauma surgeon was not a single, uninterrupted march toward some predetermined destination. It was a succession of decisions, opportunities, difficult days, long nights, and experiences that gradually built the life I have now.

To explain all of that properly would have required considerably more time than either of us had available beside the refrigerated dairy cases, and I suspect that even the most patient supermarket employee would have begun wondering whether we intended to purchase anything before the milk warmed up. So we exchanged the essential information, shared a few memories, and moved on to the subject that inevitably comes up when people reconnect after many years: what happened to everyone else?

I learned that Lauren was doing very well. She is now a marketing executive for a biotechnology company, happily married, and the mother of two children. There is something rather remarkable about hearing that sort of news about someone you knew as a teenager. In high school, the future tends to exist in a hazy, distant realm. You understand in the abstract that everyone will eventually grow up, pursue careers, get married, raise families, and become responsible for things that would have seemed impossibly dull when you were sixteen. But you do not really experience those developments as concrete possibilities. You see the people around you as they are at that moment, and the thought that the girl you are dating might one day become a professional with a family of her own is perfectly understandable without feeling particularly real.

Then the years pass, and one day her father is standing beside you in the dairy aisle telling you that she has built a good life. She has a career, a husband, and two children. Somewhere along the way, the teenager you remember became an adult with a world of her own, just as you did. The news is reassuring in a way that is difficult to articulate. You do not need to be involved in someone’s daily life to be pleased that things have worked out well for them. There is a particular kind of happiness in learning that someone from your past has found their place in the world, especially when you remember them from a time when all of you were still figuring out what that world might look like.

I found myself genuinely glad to hear it. We wished each other well, exchanged the usual expressions of surprise at how much time had passed, and eventually went our separate ways to finish our shopping. It was a pleasant encounter, the sort of conversation that leaves you smiling as you return to whatever mundane task you were doing before the past decided to make an unexpected appearance. I went back to my cart, resumed thinking about groceries, and continued through the store with the curious sensation that something had happened that morning beyond the ordinary business of buying food. I had gone to Stop & Shop because it was convenient, because it opened at seven, and because I wanted to get the shopping finished before heading home. I had not anticipated a reunion with someone who remembered me from high school, and I certainly had not expected to spend part of my morning discussing the intervening decades beside the dairy cases.

But that is one of the things I love about living in a small town, and it is a quality that becomes more apparent the longer you live away from one. In a large city, you can spend years surrounded by millions of people and remain almost entirely anonymous. You see the same faces on the train, walk past the same people on the sidewalks, and stand beside the same strangers in coffee shops without necessarily knowing anything about them. The city has its own advantages, and I spent nearly two decades in Boston building a life and career that I value enormously, but there is a certain anonymity to urban living that can make the world feel strangely disconnected. People pass through your day without leaving much of a trace, and unless you make a deliberate effort to maintain a connection, the people you once knew can disappear into the enormous machinery of city life.

Small towns operate differently. The past has a habit of remaining physically present. The people you knew in school may still live nearby, their parents may still be driving familiar cars, and the families you remember may continue shopping at the same stores, attending the same community events, and traveling the same roads they have traveled for decades. You can move away, build a career, get married, and spend years in another city, but the town itself remains a kind of living archive. Its residents carry memories of one another, and those memories sometimes resurface in the most ordinary circumstances.

That is especially true in Glocester, where the distance between your present life and your past can feel remarkably short. I have returned to the town where I grew up after spending much of my adult life in Boston, and there are moments when that decision seems to have brought the different chapters of my life into a single place. The roads are familiar. The landscape is familiar. The rhythms of rural Rhode Island are familiar. And the people who belong to that landscape occasionally appear in front of you when you least expect them, reminding you that your history is not quite as distant as you may have assumed.

After I finished shopping and paid for everything, I pushed the cart outside into the morning air and headed toward the parking lot. I had deliberately taken Sadie’s Mercedes-Benz G-Wagon to the hospital the previous night because I knew I was going grocery shopping on my way home. There was no point taking my own car to Boston, then driving home, and then heading back out to collect supplies when I could combine the errands into one trip. It was a practical decision, made for the same reason I had chosen Stop & Shop over Dino’s in Chepachet: the simplest route was the best route, particularly after an overnight shift.

As I walked toward the G-Wagon, I noticed a white Subaru parked beside it. I slowed down, looked at the car, and immediately found myself smiling. I had a suspicion about whose vehicle it was, and the suspicion was based on something I remembered from the 1990s. Steven’s family had been a Subaru family even back then. The car beside mine, or rather beside Sadie’s, seemed like an almost absurdly perfect continuation of that small detail from the past. Here I was, nearly thirty years after dating his daughter in high school, standing in a supermarket parking lot in Smithfield, and there was a white Subaru parked beside the G-Wagon. It felt like the sort of coincidence that a screenwriter would insert into a story to make the audience smile, except that nobody had written it. It had simply happened.

I looked at the license plate.

The first two letters were “FC.”

I recognized it.

I am not going to publish the entire plate here, because there is no reason to put somebody else’s vehicle information on the internet simply to prove a point, but I remember that plate from years ago. Seeing those two letters was enough to turn my suspicion into recognition. It was his car. The man I had just encountered in the dairy aisle, the father of the girl I dated in high school, was parked right beside the vehicle I had borrowed from my wife for the morning commute. And the license plate was one I remembered from the 1990s.

I stood there for a moment, probably looking rather ridiculous to anyone watching me, smiling at a Subaru in a supermarket parking lot as though I had just discovered a long-lost archaeological artifact. There was something almost comical about how thoroughly the encounter had unfolded. First, a voice from behind me in the dairy aisle. Then a familiar face. Then the University of Vermont hat that seemed to have survived the passage of time. Then the news about Lauren, her career, her marriage, and her children. And finally, outside in the parking lot, the white Subaru and a license plate whose opening letters I remembered from another era of my life.

It was a small detail, really. Two letters on a license plate should not ordinarily inspire much excitement. But memory is not always governed by the apparent importance of the things it preserves. Sometimes the mind holds on to details that seem completely insignificant at the time, only to retrieve them years later with startling clarity. A particular car, a hat, the sound of a person’s voice, a familiar route through town, or the opening characters on a license plate can become little markers of a life you once lived. They are the ordinary artifacts of memory, and every so often, one of them appears in the present with enough force to make the intervening decades feel surprisingly short.

I could not help thinking about the distance between the two versions of my life that had briefly intersected that morning. In the 1990s, I was a student at Ponaganset High School, dating Lauren, and living in a world where the future had yet to unfold. Steven knew me in that context. He knew me as the young man who was part of his daughter’s life, long before medical school, surgical training, and the responsibilities of a career in trauma and critical care. Now, nearly thirty years later, he had recognized me in a supermarket while I was buying groceries after an overnight shift in Boston. I was married to Sadie, had returned to Glocester, and was heading home to a life that would have seemed distant and abstract to the teenager he once knew.

And he was still wearing his University of Vermont hat.

His daughter was doing well. He appeared to be doing well. I was doing well. We had all moved through the years, accumulated our own experiences, and built lives that bore little resemblance to the ones we had known in high school. Yet a brief encounter in a supermarket had connected those lives without any effort on our part. There had been no planning, no online search, no carefully orchestrated reunion. We had simply been in the same place at the same time, and the recognition had followed naturally.

There is a lesson in that, although I am not inclined to turn every pleasant morning into a philosophical lecture. Life is busy enough without requiring a moral at the end of every grocery run. Still, I think we sometimes underestimate how much of our lives remains connected to the people and places that shaped us. We imagine that moving forward means leaving the past behind, and in some respects that is true. We grow up, establish careers, develop new relationships, and become people our younger selves would scarcely recognize. We acquire responsibilities and perspectives that would have been difficult to explain to the teenagers we once were. But moving forward does not erase the earlier chapters. They remain part of us, occasionally quiet for years at a time, until something as simple as a familiar face brings them back into view.

I have spent a great deal of my adult life in Boston, and I am proud of the career I built there. Trauma surgery is demanding work, and the years required to reach the point where I could serve as an attending surgeon were not always easy. There were long days, longer nights, difficult cases, and countless moments when the next responsibility arrived before I had finished processing the previous one. Medicine has a way of compressing time because so much of your attention is directed toward the immediate needs of the patient in front of you. You learn to concentrate on what must be done now, what decision needs to be made next, and what problem requires your attention before the clock moves another minute forward.

But there is life outside the hospital, and some of the most meaningful reminders of that fact arrive when you are doing something utterly ordinary. Buying groceries. Driving home. Seeing an old car. Recognizing a hat. Speaking to someone who remembers you from a time before your life took its present shape. These moments do not require much of us, but they can return a surprising amount. They remind us that we are not merely the sum of our current responsibilities, professional achievements, or daily routines. We are also the people we once knew, the places we once inhabited, and the memories that have traveled with us through the years.

Perhaps that is one of the reasons I have come to appreciate small-town life more since returning to Glocester. The connections are not always dramatic, and they are not always especially close. Sometimes they are as simple as knowing that the man standing beside the milk used to be the father of the girl you dated in high school. Sometimes they involve recognizing a vehicle in a parking lot because you remember seeing it decades ago. Sometimes they are nothing more than a brief conversation between two people who are pleased to discover that the intervening years have treated them reasonably well.

Yet those small connections contribute to a sense of continuity that can be difficult to find elsewhere. They remind you that a community is not merely a collection of houses, roads, businesses, and municipal boundaries. It is a network of shared memories, familiar faces, and overlapping lives. People move away and return. Children become parents. Students become physicians, teachers, engineers, and business executives. The people who once stood on the sidelines of your youth eventually have their own stories to tell, and every so often, those stories cross yours again in the most unexpected places.

I finished loading the groceries into Sadie’s G-Wagon, climbed into the driver’s seat, and prepared to make the final drive home. The morning was still young, the roads were beginning to fill, and the ordinary business of the day was waiting. I was tired, certainly, and I was looking forward to getting home after the overnight shift, but I found myself smiling as I started the engine. I had gone into Stop & Shop expecting nothing more than a quiet grocery run before heading back to Glocester. Instead, I had run into someone who remembered me from high school, learned that his daughter had built a happy life of her own, and discovered that the family Subaru tradition apparently remained alive and well.

It was a good reminder that you never really know when the past will decide to introduce itself. Sometimes it arrives through an old photograph, sometimes through a message from someone you have not heard from in years, and sometimes it appears in the form of a familiar voice asking whether you are the same Stephen he remembers from the 1990s. Occasionally, it even leaves its calling card in the form of a white Subaru parked beside your wife’s G-Wagon, complete with the opening letters of a license plate that your memory has somehow kept safely filed away for nearly three decades.

And that, to me, is one of the lovely things about living in a small town. You can leave for years, build a career, marry someone wonderful, return home, and assume that the past has settled comfortably into memory, only to discover that it is still out there driving around in a familiar car, wearing a familiar hat, and shopping for milk at seven in the morning.

Nearly thirty years had passed since I dated Lauren at Ponaganset High School. We had all grown up, pursued our own lives, and become people our younger selves could only have imagined. Yet for a few minutes in a supermarket in Smithfield, the distance between then and now seemed remarkably small, and the whole encounter left me with a quiet appreciation for the people who remain part of our stories long after we stop seeing them regularly.

I hope Steven and Lauren continue to do well. I hope the grandchildren are happy and healthy, that the Subaru keeps running, and that the University of Vermont hat has many more years of service ahead of it. As for me, I made it home to Glocester with the groceries, a full night’s work behind me, and an unexpected little reminder that life has a wonderful habit of bringing familiar faces back into view when you least expect them.

All of which goes to show that sometimes the most memorable part of a long night in Boston has absolutely nothing to do with the hospital, the operating room, or the trauma service. Sometimes it is waiting for you in the dairy aisle, somewhere between the milk and the half-and-half, nearly thirty years after you last expected to see it.

The Great Yellow Menace: Why School Buses Have Become the Unfazed Bullies of the Road

There is a particular time of year in New England when the leaves begin changing, the mornings turn cold enough to make you reconsider your commitment to an early jog, and the roads around town become afflicted with a familiar, unmistakable disease. It is not influenza, although the symptoms include widespread irritation, elevated blood pressure, involuntary profanity, and a sudden loss of faith in humanity. It is not seasonal allergies, although the mere sight of the offending object is enough to make your eyes narrow and your sinuses tighten. No, ladies and gentlemen, it is school bus season, and I am beginning to suspect that somewhere in the depths of the Rhode Island Department of Transportation, there is a secret committee dedicated to ensuring that the morning commute becomes progressively more miserable every year.

I am almost certain I wrote about school buses last year, or perhaps the year before that, and if memory serves, it was around this very time of year. Apparently, the subject has become an annual tradition, much like Halloween decorations, pumpkin-flavored everything, and New Englanders discovering that their heating systems have inexplicably stopped working the first night the temperature drops below forty degrees. Here I am again, sitting at the metaphorical kitchen table with my coffee, contemplating the great yellow menace that has once again descended upon our roads, and wondering how a perfectly ordinary school transportation system managed to evolve into a rolling obstacle course designed by someone who apparently has a personal grudge against people who need to get to work on time.

Now, before anyone starts sharpening their pitchforks and accusing me of wanting children to walk barefoot through a blizzard, let me establish something important. I understand that children need to get to school. I went to school. I was once a child myself, despite what my current level of cynicism might suggest, and I rode a school bus growing up in Glocester, Rhode Island. I understand that buses serve an important purpose, that children need reliable transportation, and that keeping students safe is a legitimate priority. I am not suggesting we abandon the entire concept of school transportation and return to the nineteenth century, when children presumably traveled to the schoolhouse behind a horse and buggy while dodging the occasional cow. School buses are necessary, and their drivers have an important responsibility. Nobody disputes that.

What I do dispute is the apparent modern philosophy that the existence of a school bus confers upon its driver absolute dominion over every public road the vehicle touches, with the rest of us reduced to a supporting cast in a transportation production that begins whenever the driver feels like it and ends whenever the last child has been successfully delivered from the front porch to the passenger seat. Somewhere along the way, we seem to have moved from transporting children to school to providing a personalized, concierge-level transportation service in which the entire commuting public is expected to sit patiently in the road while the bus completes its appointed rounds, negotiates family scheduling difficulties, and apparently waits for a teenager to finish whatever it is teenagers do before they are prepared to acknowledge the existence of morning.

And I would like to know when, precisely, this transformation occurred, because I do not remember it being quite this ridiculous when I was growing up.

The School Bus of My Youth Was Not a Luxury Limousine

When I rode the school bus in Glocester, the arrangement was relatively straightforward. There was a designated stop, the bus arrived, the children waiting at that stop climbed aboard, and the bus continued on its way. The entire process operated on the radical assumption that a school bus was a means of transportation rather than a mobile extension of the family driveway. If you lived a reasonable distance from the stop, you walked. If it was raining, you walked in the rain. If it was snowing, you put on a coat and walked in the snow. If it was hot, you sweated. If it was cold, you questioned your life choices while trudging along the road in the predawn darkness. This was not considered child neglect, an infringement upon human rights, or grounds for convening a municipal committee. It was simply how getting to the bus worked.

My bus stop was approximately a quarter of a mile from home, which meant that I walked a minimum of half a mile every school day just getting to and from the bus. Five days a week, through the seasons, I made that little journey. There was no elaborate negotiation with the transportation department, no request for a special pickup because the weather was disagreeable, and no expectation that the driver would pull up to my front door while my mother stood in the window waving like the Queen Mother greeting a visiting head of state. The bus stopped where it stopped, and the children adjusted accordingly.

And you know what? We survived. Miraculously, we survived walking a few hundred yards to a bus stop. We survived the rain, the cold, the occasional miserable morning when the wind came sweeping across rural Rhode Island with all the warmth and compassion of an IRS audit. We managed to get ourselves to the designated location at the designated time, and if we failed to do so, the bus did not necessarily circle the neighborhood like a yellow search-and-rescue helicopter looking for a missing expedition member. You were not at the stop? That was a you problem. There was another bus to catch, another arrangement to make, or a lesson to learn about being punctual.

I realize that times change, and I am not suggesting every child should be expected to walk the same distance regardless of age, weather, disability, road conditions, or safety. Rural roads can be dangerous, and there are legitimate reasons for providing closer pickups in certain circumstances. But somewhere between sensible accommodations and modern convenience, we appear to have lost the plot entirely. The ordinary expectation that a child can walk a short distance to an established stop has been replaced, in some places, by what looks suspiciously like a door-to-door shuttle service. And every additional pickup adds another interruption to a route that is already competing with thousands of people trying to get to work, appointments, school, hospitals, construction sites, and every other place society expects them to be.

Apparently, the new standard is that the bus must collect every child with the precision of an Amazon delivery driver, except that Amazon generally does not stop its delivery van in the middle of a busy road, activate a sequence of flashing lights, and summon an entire neighborhood to witness the handoff.

The Daily Commute Has Become a Game of Yellow-Light Roulette

The first problem, and the one that becomes apparent almost immediately after the school year begins, is the traffic. School buses hold up traffic. I know that observation is hardly worthy of a doctoral dissertation, but the scale of the problem deserves some attention, particularly for those who appear to believe that the rest of the world has nothing better to do between seven and nine in the morning than sit behind a forty-foot yellow vehicle while it works its way through a residential neighborhood one child at a time.

This is not a complaint about leaving home late and then blaming the world for one’s own poor planning. I am not talking about the person who spends twenty minutes searching for car keys, decides to shower at the last possible moment, and then discovers that traffic exists. I leave for work knowing perfectly well that the morning commute is part of the bargain. I account for the distance, the usual congestion, the occasional accident, and the unpredictable collection of hazards that accompany driving into Boston. I have no expectation that the road will be empty simply because I have somewhere important to be. I understand that other people have lives, schedules, and responsibilities of their own.

What I object to is the predictable, recurring disruption caused by a transportation system that seems increasingly indifferent to everyone outside the bus. When a school bus stops, traffic stops. When it stops again, traffic stops again. When it stops at the next house, and then the next house, and then the house across the street because apparently the child cannot possibly be expected to walk twenty yards to a common pickup point, traffic stops once more. Multiply that by several buses traveling the same roads, each with its own route, timetable, and collection of stops, and the morning commute becomes an exercise in controlled aggravation.

You can almost chart the deterioration of your mood by counting the houses. One stop? Fine. Two stops? No problem. Three stops within a quarter of a mile? All right, perhaps there is a perfectly good reason. By the seventh stop, however, you begin to suspect that the bus is not following a route so much as conducting a comprehensive census of every school-aged child in the neighborhood. At the tenth stop, you are wondering whether the driver has been instructed to collect children individually by their bedroom windows, and at the fifteenth, you have begun calculating whether it would be faster to turn around, drive home, resign from your job, and become a lighthouse keeper somewhere along the Maine coast.

The maddening thing is that none of this is unexpected. These routes recur five days a week throughout the school year. The same buses travel the same roads at roughly the same times, and the same commuters encounter the same bottlenecks. This is not an unforeseeable act of nature. It is a routine transportation problem, and routine transportation problems are precisely the kind that ought to be addressed through planning, sensible routing, and an honest assessment of how public roads are being used.

I remember that our bus on Snake Hill Road used to pull over to the side to let cars pass. Think about that for a moment. A school bus driver recognized that the road was being shared with other people and made an effort to keep traffic moving when circumstances permitted. Nobody needed to write a dissertation on civic responsibility. Nobody had to invent a new traffic-management philosophy. The driver simply acknowledged that a line of vehicles might be accumulating behind the bus and, when it was safe and practical, made room.

Today, the attitude can feel rather different. The bus occupies the road, the traffic stacks up behind it, and everyone else is expected to accept the delay as an unavoidable feature of civilization. There is no apparent urgency to keep things moving, no visible concern for the growing procession of cars, and certainly no indication that the person behind the wheel is losing any sleep over the fact that twenty or thirty commuters may now be running late because the bus has decided that this particular stretch of road is its personal loading zone.

Of course, buses cannot safely pull over everywhere, and drivers should never be pressured into making dangerous maneuvers simply to appease impatient motorists. Safety comes first. But there is a difference between taking the time necessary to transport children safely and treating the entire roadway as though every other driver has been placed on indefinite administrative leave. One is responsible driving. The other is what happens when a necessary public service becomes so insulated from criticism that nobody seems interested in asking whether the system could work better.

The Orange Lights: A Warning, a Promise, and Apparently a State of Mind

Then there are the lights, which deserve a discussion of their own because I am convinced that the average school bus has more flashing signals than a small airport runway. You approach a bus, and the amber lights begin flashing. You slow down, watch carefully, and try to determine what is happening. Is the bus preparing to stop? Is it about to pull over? Is a child about to appear from somewhere near the roadside? Is the bus simply announcing that it is considering the possibility of stopping at some unspecified point in the near future?

You are left interpreting the visual equivalent of an ambiguous text message from someone who refuses to tell you whether they are coming to dinner.

School bus warning systems exist for a reason. Amber warning lights generally indicate that a stop is being prepared, while red flashing lights and an extended stop arm signal that traffic must stop under the applicable law. The precise rules depend on the situation and jurisdiction, but the underlying principle is straightforward: drivers need clear, predictable signals so that they can respond appropriately. These are not decorative lights. They are safety equipment intended to prevent children from being struck by passing vehicles.

And yet, I routinely find myself watching buses with amber lights flashing for what seems like an eternity, wondering whether I should expect the vehicle to stop immediately or continue down the road for another quarter of a mile. The problem is not that a driver uses the warning system as intended. The problem is that uncertainty can arise when signals appear to be activated long before a stop is imminent, remain active through prolonged periods of hesitation, or seem disconnected from any immediately apparent maneuver. A driver approaching from behind should not have to conduct a psychological assessment of the bus operator to figure out what the next thirty seconds might look like.

If the bus is preparing to stop, the warning should communicate that intention clearly and in accordance with the rules. If the bus is not preparing to stop, then the lights should not leave everyone around it guessing. Consistency is not an unreasonable expectation when the equipment in question is designed to warn motorists about a potentially life-threatening situation.

And let us be clear about something else: I am not advocating that motorists ignore flashing lights, pass a stopped school bus, or gamble with a child’s safety because they are irritated about being delayed. That would be idiotic. When red lights are flashing and the stop arm is extended, you stop as required by law. You do not decide that your appointment is more important than a child’s life. There is no argument to be had about that. My objection concerns the operational habits that make an already congested commute more confusing than it needs to be, not the safety protections themselves.

A properly functioning warning system should make the road more predictable, not turn every encounter with a school bus into a guessing game. The irony is that the more routinely motorists see ambiguous or prolonged signaling, the more likely they are to become frustrated by it, and frustration is precisely the state of mind we do not want people entering when children are getting on and off buses. Predictability protects everyone. Confusion helps nobody.

The Great Doorstep Expedition of 2026

Now we come to the issue that truly tests my patience: the apparent transformation of the school bus into a personalized pickup service for children who cannot be expected to make their own way to a designated stop.

I am serious when I say I remember walking to the bus stop in Glocester. I remember having to be there on time. I remember that if the bus arrived and you were nowhere to be found, the driver did not necessarily wait around while your family conducted a search-and-rescue operation through the house. The bus had a route, the route had a schedule, and you were expected to participate in the arrangement like a reasonably functioning member of society.

Today, some morning routes seem to operate on an entirely different philosophy. The bus stops at one house, then another, then another, with the children collected individually as though they were important diplomatic passengers being transported to an international summit. There is no central gathering point, no obvious effort to consolidate stops, and no sense that the cumulative effect of these decisions might matter to the hundreds of people who are following behind.

I would love to know how much time could be saved across an entire school district by establishing sensible pickup points where children can safely walk a short distance, rather than dispatching a bus to every individual driveway. Perhaps there are legitimate logistical reasons for certain stops, and I would be the first to acknowledge that some children need accommodations. But surely there is a middle ground between making a child walk half a mile in the snow and having a forty-foot bus perform a private house call at every residence.

We seem to have become deeply uncomfortable with the idea that convenience has a cost, especially when that cost is paid by somebody else. A parent wants the child picked up directly outside the house, so the bus stops there. A child is not quite ready, so the bus waits. Someone has forgotten something, so the morning schedule bends around that too. Each individual exception may seem harmless in isolation, but when every exception becomes routine, the cumulative effect is a system that operates on the assumption that the time of the person making the request matters more than the time of everyone else.

The bus driver is not necessarily responsible for this. In many cases, the driver is following a route established by the school district, and the rules governing pickup locations may be entirely outside the driver’s control. The transportation department decides where the stops go, administrators determine the policies, and families operate within the system they have been given. I understand all of that. But somebody, somewhere, ought to be asking whether a route with twenty individual pickups is actually the best way to move twenty children through a neighborhood during the busiest hour of the morning.

We have traffic engineers, route-planning software, geographic information systems, and enough computing power in an ordinary smartphone to put a man on the Moon, yet we appear to be incapable of solving the problem of getting a group of children from their neighborhoods to school without bringing half the town to a standstill. Surely we can do better than a rolling parade of yellow steel, stopping every few houses like a particularly unambitious sightseeing tour.

And before anyone accuses me of being an unreasonable old man shaking his fist at the clouds, let me point out that I am not even particularly old. I am old enough to remember how things used to work, young enough to recognize that technology can improve nearly everything, and experienced enough to understand that convenience and efficiency are not necessarily the same thing. Sometimes we make a system more convenient for a small number of people while making it dramatically less efficient for everyone else. That is not progress. That is merely the redistribution of inconvenience.

The Incident That Finally Pushed Me Over the Edge

All of the above is irritating, certainly, but irritation alone would not have compelled me to revisit this subject. The reason I am writing about school buses today is that I witnessed something on the road that seemed to encapsulate the entire problem in one absurd little morning performance.

A school bus stopped in the road in front of a house. Not pulled neatly into a safe, designated area where traffic could continue if appropriate, but stopped there in a manner that brought the situation directly to the attention of everyone approaching from behind. The amber warning lights were flashing, and then, because apparently the visual announcement had not conveyed the urgency of the situation sufficiently, the driver began honking the horn to summon the child from the house.

Let us consider that for a moment. We have a large school bus stopped in the roadway, warning lights flashing, traffic accumulating behind it, and a driver honking to get a child out of the house. The bus has effectively become a mobile alarm clock with a diesel engine, and the entire commuting public has been conscripted into the wake-up process.

I could practically imagine the internal logic of the operation. The bus has arrived. The child is not ready. Rather than continuing along the route and allowing the family to make another arrangement, the bus will remain stationary and announce its presence through the traditional methods of the impatient delivery driver: flashing lights and an increasingly insistent horn. The rest of us can wait. We are not going anywhere. We have become unwilling participants in a suburban stage production whose opening act is a teenager getting out of bed.

And then, as though the scene needed one final flourish to bring the whole spectacle into focus, the mother emerged from the house with her teenage son, who was apparently sporting the now-familiar broccoli haircut, and the pair proceeded to document his boarding process on video.

Yes, video.

There was a mother, a teenage boy, a school bus occupying the road, and a camera recording the great expedition from the front door to the yellow vehicle. I watched the scene unfold and found myself wondering whether we had collectively lost the ability to distinguish between something worth documenting and the ordinary administrative business of getting a child to school. Was this a historic occasion? Was the teenager embarking on his first day of school after a decade-long absence? Was he being sent to an undisclosed location for a dangerous diplomatic mission? Had he just returned from scaling Everest, and was this the triumphant homecoming footage?

No. He was getting on a school bus.

Perhaps there was a reason for the recording. Perhaps the mother was filming something unrelated to social media, or perhaps it was an inside joke between them. I cannot know her intentions, and I am not going to pretend that I can read somebody’s mind from the driver’s seat of my car. But the scene looked so much like the modern compulsion to turn every mundane event into content that I could not help thinking of TikTok, Instagram, and the broader culture in which ordinary life apparently does not count unless somebody has captured it on a phone.

We have reached a point where a teenager cannot simply get on the bus without the possibility that the event must be documented, edited, captioned, and released to an audience that may or may not care. Perhaps the video will be accompanied by music, a clever transition, or a caption about being late for school. Perhaps it will receive twelve likes from friends who were themselves late for school that morning. Perhaps it will disappear into the digital graveyard of forgettable content within twenty-four hours. The internet is an enormous place, and somewhere in it there is undoubtedly an audience for a video of a teenager walking fifteen feet from his front door to a school bus.

But I have a question that I think deserves asking: if there is enough time to stage and film the departure, why is there not enough time to get the teenager outside before the bus arrives?

I am not suggesting that every parent who films a child is irresponsible, nor am I suggesting that the mother in question deliberately set out to inconvenience everyone on the road. The issue is the contradiction between the urgency implied by the bus honking in the street and the apparent willingness to turn the eventual boarding process into a recorded event. If the child is late, the immediate priority should be getting the child onto the bus safely and allowing the route to continue. If the family needs additional time, the transportation arrangement should account for that without turning a public road into a waiting room.

And if a parent has enough time to come outside and film the process, I cannot help wondering whether there might also be enough time to put the teenager in the family car and drive him to school. That would allow the bus to continue its route, the commuters to proceed with their mornings, and the rest of us to avoid being involuntary extras in a social-media production about the thrilling adventure of boarding a yellow vehicle.

I realize that driving a child to school is not always possible, and I am not suggesting that every family has the time, resources, or flexibility to do so. Many parents are working difficult schedules, managing multiple children, and doing their best with the arrangements available to them. But in this particular situation, watching a bus honk in the road while a parent emerged with a camera to film her already-late teenage son was the sort of experience that makes a person stare at the windshield in disbelief and wonder whether the world has become a very elaborate practical joke.

The bus was waiting. The road was obstructed. The child was late. And somehow, the camera still made the guest list.

The Broccoli-Haired Generation and the Death of the Morning Schedule

I should probably explain that the broccoli haircut itself is not the real problem, although it has become one of those cultural phenomena that makes a person wonder who decided the human head should resemble a vegetable garnish. Every generation has its hairstyles, and mine certainly produced enough questionable fashion choices to keep future historians employed. I am not going to pretend that the young men of my era all looked like they had stepped out of a Renaissance portrait. We had our own disasters, and photographs from the late 1990s provide more than enough evidence.

The haircut simply completed the picture. Here was a teenager, apparently running late, being filmed as he made his way to a bus that had stopped in the road to summon him. The whole scene seemed to represent a broader cultural shift in which punctuality has become negotiable, personal convenience is treated as an entitlement, and the ordinary responsibilities of daily life are increasingly subordinated to whatever happens to be occupying someone’s attention at that moment.

I am not particularly interested in lecturing teenagers about discipline from a mountaintop. Adolescence has always involved a certain amount of disorganization, questionable judgment, and the conviction that adults are unreasonable. I remember being a teenager. I remember the sensation that the world operated according to rules invented specifically to make my life more difficult. I also remember that if I missed the bus, the consequences were generally mine to deal with, not the responsibility of every driver behind the bus who happened to be trying to get to work.

There is something useful about learning that a schedule means what it says. If the bus arrives at a particular time, you should be ready at that time. If you are not ready, you may miss it. That is not cruelty. It is an ordinary consequence of how shared transportation works. Trains do not generally wait because a passenger is still looking for a shoe, and commercial flights do not hold departure because someone has decided to finish breakfast after boarding has begun. There are exceptions for legitimate operational reasons, of course, but the general principle is that the individual must make a reasonable effort to meet the schedule rather than expecting the schedule to bend indefinitely around the individual.

A school bus route is not a private taxi service, and the driver should not be expected to function simultaneously as chauffeur, alarm clock, neighborhood watchman, and personal attendance coordinator. If a child repeatedly misses the bus, the solution should involve the family and the school transportation system, not a daily ritual of honking in the street while a line of commuters waits for the teenager to make his public debut.

There is also a larger lesson here about the value of other people’s time. The commuter behind the bus may be heading to a hospital to begin a shift, driving to a construction site, opening a small business, attending an appointment, or trying to get to work before a supervisor begins wondering where everyone has gone. That person’s schedule is not less legitimate because it is invisible to the family standing on the sidewalk. We have a habit of treating delays as trivial when they affect strangers, even though those strangers are living lives every bit as complicated as our own.

The bus driver sees the child who needs to get to school. The parent sees the teenager who needs to be delivered safely. The teenager sees, perhaps, the opportunity to be filmed before the first class of the day. Meanwhile, the person behind the bus sees the clock moving and wonders why a routine transportation arrangement has turned into a public demonstration of the proposition that everyone else’s time is expendable.

The Unfazed Bullies of the Road

Now we arrive at the behavior that has earned school bus drivers their special place in my morning hierarchy of aggravations: the extraordinary confidence with which some of them maneuver these enormous yellow vehicles through traffic.

A school bus is not a small machine. It is a massive piece of equipment, conspicuous enough to be seen from space by anyone with functioning eyesight, and heavy enough that a collision with an ordinary passenger vehicle is unlikely to be a pleasant experience for the occupants of the smaller car. The driver knows this. Everyone else knows this. And there is a certain psychological advantage in being behind the wheel of a vehicle that occupies half the road and can make an ordinary sedan look like a child’s toy.

I have watched buses pull into heavy traffic with the serene confidence of a man entering his own living room. There is no apparent hesitation, no visible acknowledgment that the traffic stream is already moving, and no sense that the driver might benefit from waiting for a reasonable gap. The bus simply begins moving, and the rest of us are expected to make the necessary adjustments because nobody particularly wants to test the laws of physics against a vehicle weighing several tons.

It is a remarkable form of road diplomacy. The bus signals its intention, begins to move, and effectively informs the surrounding traffic that a new arrangement has been reached. The arrangement is that the bus goes where it wants, when it wants, and everyone else will sort out the details.

I have seen buses occupy busy intersections while making their turns, forcing other vehicles to wait as the driver maneuvers through a space that appears to have been designed for something considerably smaller. I have seen them swing wide to negotiate turns, cutting across portions of adjacent lanes and leaving nearby drivers to brake or reposition themselves. I have watched them move along roads at a pace that seems unrelated to the posted speed limit, creating long lines of traffic behind them while the driver proceeds with the unhurried tranquility of someone enjoying a Sunday drive through the countryside.

Now, before someone sends me a lecture about the dimensions of school buses, I understand that they need room to turn. A bus cannot negotiate a tight corner in the same way a compact car can, and a professional driver must account for blind spots, vehicle length, turning radius, road conditions, and the safety of children aboard. A school bus should never be driven aggressively merely to keep impatient commuters happy. Nor should a driver take a turn too quickly or attempt a maneuver that puts students at risk.

But there is a difference between making a necessary wide turn and treating every lane marking as a polite suggestion. There is a difference between merging carefully into traffic and assuming that the size of the vehicle entitles you to merge regardless of the circumstances. There is a difference between proceeding cautiously and moving so slowly, without an apparent operational reason, that a dozen vehicles begin accumulating behind you while you remain blissfully unaware of the traffic situation you have created.

The problem is not the bus itself. The problem is the attitude that seems to accompany certain encounters with it: an almost supernatural lack of concern for the inconvenience imposed on others. Some drivers behave as though their responsibility to the children aboard somehow absolves them of any obligation to consider the traffic around them. They are transporting children, therefore they are engaged in a noble activity, therefore the rest of society must yield without complaint.

I have a suggestion. Being responsible for children does not grant anyone a temporary exemption from courtesy, situational awareness, or the ordinary requirements of safe driving. In fact, it should demand more of all three. The larger the vehicle, the greater the responsibility to operate it predictably. The more vulnerable the passengers, the more important it becomes to avoid creating unnecessary hazards. And the more frequently a vehicle uses a particular road, the more reason there is to establish sensible procedures that allow it to do so without routinely creating chaos.

The irony is that the drivers who behave most imperiously may be undermining the very public goodwill that makes their job easier. Most motorists are perfectly willing to accommodate a school bus making a legitimate stop. We understand why traffic must stop when children are boarding or leaving. We understand that the driver has responsibilities that outweigh our desire to get through the intersection thirty seconds sooner. But patience is not an inexhaustible resource, and it becomes harder to maintain when the same vehicle appears to treat every inconvenience it creates as somebody else’s problem.

I am going to say it, and I suspect some people will agree with me even if they are too polite to admit it: some yellow school bus drivers are the unfazed bullies of the road. They do not need to shout, gesture, or engage in a confrontation. The bus itself does the talking. It occupies the lane, takes the turn, blocks the intersection, and proceeds at its own pace, secure in the knowledge that nobody wants to be the person who tangles with a school bus.

It is the vehicular equivalent of a large man walking through a crowded restaurant without looking where he is going because he assumes everyone else will move out of his way. Perhaps the people around him do move. Perhaps nobody wants to make a scene. But the absence of a confrontation does not mean his behavior is courteous, and the fact that a bus can impose its will on surrounding traffic does not mean that doing so is always appropriate.

There is a reason professional drivers are expected to exercise judgment rather than merely operate machinery. Driving is not simply the act of pointing a vehicle in a direction and pressing the accelerator. It involves reading the road, anticipating the behavior of others, recognizing when a maneuver will create a hazard, and understanding that the vehicle’s presence changes the environment around it. A good driver does not merely know how to move a large vehicle; a good driver knows how to move it without making everyone else feel as though they are participating in a demolition derby.

And for the record, I have no doubt that many school bus drivers are excellent at what they do. They get up early, deal with weather and traffic, manage the responsibilities of transporting children, and perform a job that can be difficult and underappreciated. I am not suggesting that every driver is careless, discourteous, or oblivious. But the ones who are can make a lasting impression, particularly when their daily route intersects with the daily commute of people who have already been awake for several hours and have no desire to begin the morning by negotiating with a mobile yellow fortress.

The Great Traffic Equality Experiment

What makes the school bus problem so maddening is that it exposes an uncomfortable truth about how we think about public space. We all share the road, but we do not always behave as though the interests of other people deserve equal consideration. We are quick to defend our own convenience and remarkably willing to dismiss the inconvenience we impose on strangers.

A parent wants a child picked up at the driveway because it is easier than walking to a designated stop. A transportation department accommodates the request because it appears reasonable in isolation. The bus driver follows the route because that is the assignment. The commuter behind the bus absorbs the delay because there is no practical alternative. Nobody necessarily intends to create a problem, yet the cumulative result is a system in which the same people are inconvenienced over and over again while the people benefiting from the arrangement have little reason to reconsider it.

This is how inefficient systems survive. The costs are distributed among hundreds of people, each of whom experiences the delay as a minor annoyance rather than a problem worth organizing around. Meanwhile, the benefits are concentrated among the people receiving the convenience. The child gets picked up closer to home. The parent avoids the morning drive. The transportation system completes the route as designed. Everyone has a reason to consider the arrangement acceptable, except the people who must sit behind it.

Imagine applying the same logic to every other form of transportation. What if every commuter decided that the train should wait an extra two minutes because they were still walking toward the platform? What if every passenger on an airplane expected the crew to delay departure while they finished a phone call? What if every delivery driver stopped in the middle of a busy road to honk until the recipient emerged from the house? We would immediately recognize that a system built around the indefinite accommodation of individual lateness would become dysfunctional.

Yet when the same principle appears in a school bus route, we are often expected to regard it as beyond criticism because children are involved. That is an emotional shield, not a transportation strategy. Children deserve safety, reliable transportation, and reasonable accommodations. They do not require an entire community to pretend that time and traffic cease to matter whenever a bus approaches a residential street.

The sensible answer is not to strip away safety protections or force every child to walk an unreasonable distance. It is to design routes intelligently, establish appropriate pickup points, communicate schedules clearly, and hold everyone involved to reasonable expectations. Transportation departments should review whether the number and placement of stops make sense. Schools should communicate pickup policies to families. Parents should ensure children are ready when the bus arrives, within the practical limits of their circumstances. Drivers should use warning systems consistently, operate predictably, and avoid unnecessary obstruction whenever safety permits.

None of this is revolutionary. It is the sort of ordinary administrative competence that should be expected of any system responsible for moving large numbers of people through a shared environment. We do not need to abolish school buses. We need to stop pretending that the way we operate them cannot be improved.

And if the response is that the morning commute is simply inconvenient and everyone should learn to live with it, I would suggest that the same argument could be made about almost every inefficient process ever devised. There is always a reason something takes longer than necessary. There is always a person who benefits from the existing arrangement. There is always a suggestion that the people affected should simply be more patient. At some point, however, patience becomes an excuse for refusing to solve a problem.

A Modest Proposal for the Yellow Menace

I have a few suggestions, and I promise none of them requires launching the buses into the sun, although I reserve the right to reconsider that proposal after another morning behind a vehicle that stops every hundred yards.

First, school districts should take a serious look at route design. Where safe and practical, children should be collected at common pickup points rather than at every individual house. The goal should not be to make children walk unreasonable distances, nor to ignore legitimate safety concerns, but to eliminate redundant stops that add substantial time without providing a meaningful benefit. Rural communities need flexibility, and urban neighborhoods present different challenges, but those differences make thoughtful planning more important, not less.

Second, pickup schedules should mean something. If a bus is scheduled to arrive at 7:15, families should be encouraged to have the child ready before 7:15 rather than treating that time as the beginning of a negotiation. A brief delay for an unavoidable circumstance is one thing. A recurring pattern in which the driver must honk, wait, and summon a late passenger is another. If a family repeatedly cannot meet the pickup schedule, the district should work with that family to find a workable solution rather than institutionalizing the delay for everyone else.

Third, warning lights and stop procedures should be used consistently and in accordance with the law. Amber lights are meant to prepare surrounding motorists for a stop, not leave them guessing about the bus’s intentions indefinitely. Red lights and stop arms must be respected without exception when required. The objective should be clarity and predictability, because those are the qualities that help motorists respond safely.

Fourth, school bus drivers should receive the same kind of professional feedback expected of other commercial drivers. If a driver routinely blocks an intersection unnecessarily, makes unsafe turns, merges carelessly, or creates avoidable confusion, the behavior should be reviewed. That does not mean punishing drivers for the unavoidable physical limitations of a large vehicle. It means distinguishing between what a bus must do and what it does merely because nobody has challenged the practice.

Finally, perhaps we could acknowledge that a school bus route is a public service, not a private convenience arrangement. The driver is responsible for transporting children safely, the school district is responsible for establishing workable policies, parents are responsible for preparing their children as circumstances permit, and motorists are responsible for obeying traffic laws and exercising patience around school buses. Everyone has a role, and everyone should be expected to fulfill it.

That last point matters because the solution cannot simply be to blame the bus driver. Many drivers are working within rules they did not establish, on routes they did not design, with schedules they may have little authority to change. If a district has constructed a route that requires a bus to stop at thirty individual houses, the driver cannot magically turn it into a more efficient route through sheer force of will. If a family has been told that the bus will wait at the curb, the driver may be under pressure to honor that arrangement. The people who design the system need to be willing to examine its results, rather than expecting the people stuck in traffic to accept them as a law of nature.

There is a difference between criticizing the people doing a job and criticizing the way the job has been organized. I can respect the difficulty of driving a school bus while questioning whether the route makes sense. I can appreciate the importance of transporting children safely while wondering why a parent appears to have time to film a late departure but not enough time to get the child outside before the bus arrives. I can acknowledge the legitimate need for warning lights while questioning why their use sometimes seems to make the morning road environment more confusing than it ought to be.

These ideas are not contradictory. They are the basis of a reasonable conversation about how to make an essential public service work better for everyone.

In Defense of the Commuter Who Just Wants to Get to Work

There is one final point I want to make, because I suspect that anyone who complains about school buses is immediately placed into the category of heartless motorists who hate children. That is a convenient way to dismiss criticism without addressing the substance of it, and it is intellectually lazy.

I do not hate children. I was one. I want children to get to school safely, receive an education, and grow into adults who understand that living in a community involves both rights and responsibilities. I want school bus drivers to have safe working conditions, reasonable schedules, and the resources necessary to do their jobs properly. I want parents to have dependable transportation for their children, especially when their own work schedules make the morning routine complicated. None of those desires requires me to pretend that every existing transportation policy is sensible or that every driver behaves appropriately.

I also want the person driving to work to be treated as a human being whose time matters. That person may be a nurse heading into a hospital, a teacher preparing a classroom, a tradesperson trying to reach a job site, a parent attempting to get to work before the childcare center closes its drop-off window, or a physician driving toward a hospital where somebody is waiting for care. Their lives do not become less important because they happen to be behind a school bus rather than sitting inside one.

The problem with traffic is that it is easy to view the people around us as anonymous obstacles. The driver behind you becomes a car in the mirror. The driver ahead becomes an inconvenience. The person waiting at the intersection becomes a delay. We forget that every vehicle contains somebody with a destination, a schedule, and a set of responsibilities that may be just as pressing as our own.

A well-run transportation system recognizes that reality. It does not assume that one group of road users matters and everyone else should simply absorb the consequences. It tries to balance competing needs, minimize unnecessary delays, and make the movement of people as safe and predictable as possible. School buses are an essential part of that system, but they do not exist outside it.

The commuter who is frustrated by a bus stopping every hundred yards is not necessarily a villain. The parent who wants a child to be safe is not necessarily unreasonable. The driver who is following a prescribed route is not necessarily indifferent. But when these individual interests collide, the answer should be to improve the arrangement rather than dismiss the frustration of everyone who has to live with it.

I am perfectly willing to stop for a school bus when its red lights are flashing and its stop arm is extended. I will wait for the children to cross. I will give the bus room to maneuver, and I will not attempt to squeeze past it because I happen to be running late. Those are the rules, and they exist for good reason. What I am less willing to do is accept the proposition that an unnecessarily inefficient route, a chronic failure to meet pickup schedules, or careless driving should be beyond discussion simply because the vehicle happens to be yellow and carries children.

Safety deserves respect. Inefficiency deserves scrutiny. Courtesy should run in both directions.

And if a school bus driver has to choose between making an unsafe maneuver and delaying traffic, the answer is obvious: delay the traffic. Nobody should ever be pressured into taking a dangerous risk to shave a few minutes off somebody else’s commute. But if the delay is caused by poor planning, unnecessary stops, inconsistent procedures, or a routine expectation that the bus will wait for people who are not ready, then the appropriate response is not to tell commuters to develop more patience. It is to fix the underlying problem.

The Yellow Menace Returns Tomorrow Morning

Tomorrow, the alarm will go off at four in the morning, and I will get up, lace up my running shoes, and head out into the New England cold. The air will probably be crisp, the roads quiet, and the world will briefly feel like a place where things make sense. I will return home, have breakfast, get ready for work, and begin the drive toward Boston with the usual understanding that traffic is part of the arrangement. There will be other cars, trucks, construction vehicles, and people trying to get somewhere. That is life, and I have made my peace with it.

Then, somewhere along the way, I will encounter the first school bus.

The amber lights will begin flashing, and I will ease off the accelerator. The bus will slow, then perhaps stop. A child will climb aboard, and I will wait. The bus will pull away, travel a short distance, and stop again. Another child will appear. Somewhere behind me, a commuter will glance at the clock. The bus will continue along the road, and the traffic behind it will grow. Perhaps it will pull over when safe to allow vehicles to pass, as my old bus on Snake Hill Road used to do. Perhaps it will not. Perhaps the next stop will be perfectly reasonable, and perhaps the one after that will involve a horn, a late teenager, and a parent emerging with a smartphone to capture the moment for posterity.

I will undoubtedly sigh, because I am human and my patience has limits. I will probably mutter something unprintable about the modern world, although I will keep my eyes on the road and obey the law. And if the bus driver makes a wide turn, blocks an intersection, or merges into traffic with the confidence of a tank commander, I may find myself revisiting the entire argument presented here, complete with the growing conviction that the yellow school bus has become the most powerful symbol of unaccountable inconvenience on the American roadway.

But I will stop when I am supposed to stop, because children deserve to arrive at school safely. That principle is not negotiable, and no amount of morning aggravation changes it.

What is negotiable is how we get there. We can design better routes, establish sensible pickup points, encourage punctuality, use warning systems consistently, and expect professional drivers to operate their vehicles with consideration for the traffic around them. We can recognize that parents have difficult mornings without allowing every family’s schedule to dictate the movement of an entire neighborhood. We can respect the essential work of school bus drivers without treating their vehicles as rolling monarchies whose occupants are exempt from the ordinary expectations of courtesy and efficiency.

Most importantly, we can stop confusing inconvenience with necessity. Some delays are unavoidable, and some precautions are worth every second they cost us. Others are the predictable consequences of systems that have never been adequately questioned because everyone involved has become accustomed to the way things are. The fact that we have always done something a certain way does not mean it is the best way to do it.

So, yes, we need to talk about school buses. We need to talk about the traffic they create, the proliferation of individual pickups, the confusing use of warning lights, the expectation that buses will wait for late passengers, and the occasional driving habits that make an enormous vehicle seem less like a transportation tool and more like an instrument of road-based intimidation. We need to talk about the difference between protecting children and indulging every inconvenience, between exercising caution and ignoring the needs of everyone else, and between providing an essential service and allowing that service to operate without meaningful scrutiny.

I remember walking to my bus stop in Glocester, Rhode Island, rain or shine, hot or cold, and getting there because that was what you did. I remember a bus driver who occasionally pulled to the side to let traffic pass, recognizing that the road belonged to more than one person. I remember a time when the bus came, the children climbed aboard, and the route continued without a production worthy of a reality television series.

Perhaps those memories are colored by nostalgia. Every generation tends to remember its own childhood as a time when things were simpler, and I am certainly not immune to that tendency. But nostalgia is not always wrong, particularly when it reminds us of something practical we seem to have forgotten: a little personal responsibility can make life easier for an awful lot of people.

The bus does not need to stop at every driveway. The teenager does not need a personal escort from the front door. The parent does not need to document every ordinary morning as though a child boarding a bus is an event of international significance. And the driver does not need to approach every merge, turn, or intersection with the serene confidence that the rest of the world will simply get out of the way.

School buses are necessary. Children deserve safe transportation. Bus drivers deserve respect for a difficult job. All of that is true.

But so is this: the rest of us have places to be, and the road is not the private kingdom of the yellow school bus.

Now, if you’ll excuse me, I need to set my alarm. Four o’clock comes early, and somewhere out there, a broccoli-haired teenager may or may not be ready for the bus tomorrow morning. I would hate to miss the next episode.

A Fall Day at the Homestead: Clinic, Garbanzo Bean Soup, Lawn Mowing, and a Little Science Fiction

There is a particular rhythm to life in New England once October settles in, a subtle shift in the air that announces itself long before the trees have entirely surrendered their green. The mornings become sharper, the evenings arrive a little sooner, and the familiar routines of summer begin to acquire the quieter, more deliberate character of autumn. Out here at the homestead, where the fields give way to woods, the trails wind through the property, and our pond sits quietly beneath the changing sky, these seasonal changes are difficult to miss. You feel them before you see them, particularly at four o’clock in the morning, when most of the civilized world is still tucked beneath its blankets and the only people awake seem to be those heading to an airport, returning from a night shift, or making questionable decisions about their sleep schedules. Sadie and I, apparently, belong to the first category of people who have decided that getting up before dawn is a perfectly reasonable way to begin a day.

This morning, the alarm went off at 4:00 a.m., and we began the familiar process of convincing ourselves that getting out of bed was preferable to remaining there. The temperature outside was hovering around 44 degrees, brisk enough to make the first step into the morning air feel like a small act of personal defiance, although there was no frost on the ground yet. That distinction matters in October. We have reached the point in the year when summer has unquestionably packed its bags, but winter has not yet arrived to collect the deposit. The grass was damp with dew, the air carried that clean, earthy smell that comes with cool mornings, and the darkness still held firmly over the property. Somewhere beyond the house, the pond lay hidden in the early gloom, while the trees stood motionless against the dim outline of the sky.

Sadie and I headed out for our morning jog, following the routine that has become such a dependable part of our lives. There is something wonderfully uncomplicated about running before the day begins making demands on you. No telephone calls, no clinic schedules, no patient charts, no administrative obligations, no messages that somehow manage to acquire an air of urgency simply because somebody has sent them before sunrise. There is just the road, the cool air, the steady rhythm of our footsteps, and the gradual awakening of the countryside. We have demanding professional lives, and our schedules do not always cooperate with the idea of a leisurely morning, so those early hours have become a small piece of territory that belongs to us. By the time most people are considering whether they want coffee or tea, we have already been outside, exercised, and begun preparing for the day ahead. It is not necessarily glamorous, but then again, very few worthwhile routines are glamorous when viewed from the perspective of someone who would rather be asleep.

After our jog, we returned to the house, where breakfast and the usual morning preparations awaited us. The kitchen gradually became the center of activity, as it so often does, with the familiar business of putting together something to eat, getting dressed, gathering whatever we needed for work, and making sure we were both reasonably prepared to face the day. Sadie and I have settled into a domestic rhythm that works for us, even though our respective professional responsibilities can make our schedules rather unforgiving. She has her own demanding world of medicine, critical care, and clinical responsibilities, while mine involves the usual assortment of trauma and acute care surgery, intensive care, teaching, and the endless work that accumulates around the practice of medicine. We leave the house in different directions, carry different responsibilities, and spend much of our working days in environments where decisions matter enormously, but we return to the same home at the end of the day, which provides a welcome degree of continuity in lives that can otherwise feel as though they are permanently in motion.

Today was my clinic day, and although the official schedule began at 8:00 a.m., anyone who has spent much time working in a hospital understands that the printed schedule rarely tells the whole story. My day began considerably earlier, with rounds on patients before settling into the business of clinic. There are always people to see, clinical questions to address, and details that need attention before the first scheduled appointment even arrives. A hospital has its own internal clock, and it does not pay much attention to the hours printed on an office calendar. Patients need to be assessed, plans need to be reviewed, and the work of the previous day must be reconciled with whatever has happened overnight. Even on a day that is technically devoted to outpatient care, the inpatient side of the practice remains very much alive, and it is often necessary to move between these different responsibilities without making a particularly elaborate ceremony of the transition.

Fortunately, today turned out to be one of those clinic days that reminds you why you continue to enjoy the work, even when the schedule is demanding and the administrative machinery surrounding modern medicine occasionally threatens to consume more time than the medicine itself. Clinic was exceptionally good, one of the better clinic days I have had in quite some time. The appointments moved along nicely, the conversations with patients were productive, and the usual collection of follow-ups, questions, examinations, and decisions seemed to fall into a natural rhythm. There was enough to keep me busy without creating the sense that I was constantly chasing the clock, and before long, I realized that the morning had passed remarkably quickly.

I have always appreciated those days when the work seems to flow rather than fight you at every turn. Medicine is not a profession in which every problem has a tidy solution, and certainly not one in which every patient arrives with a textbook presentation, a complete history, and a conveniently organized set of investigations. Much of the job involves sorting through uncertainty, explaining what we know and what we do not know, helping patients understand their options, and making decisions that account for the person sitting in front of us rather than merely the information displayed on a computer screen. There is a certain satisfaction in having enough time to do that properly, to listen without feeling as though the next appointment is already knocking on the door, and to leave an encounter knowing that the patient has been heard and that the plan makes sense. Those are the days that restore a little of your faith in the ordinary machinery of clinical practice, and today offered a welcome reminder of how enjoyable the work can be when everything falls into place.

Of course, there was another rather excellent feature of today’s schedule, one that had nothing to do with clinic efficiency or the successful management of follow-up appointments. At some point around lunchtime, I managed to slip away from my office and make the short trip to Sadie’s office, which is only a couple of blocks away at the hospital. One of the understated advantages of being married to another physician who works nearby is that, occasionally, our professional lives intersect in a way that allows us to do something rather ordinary and rather lovely: have lunch together in the middle of a workday. We are both busy enough that these opportunities cannot always be taken for granted, and there is something reassuring about being able to step away from the hospital’s constant hum, even briefly, and sit down with your wife rather than eating whatever happens to be available while reviewing charts or answering messages.

When I arrived, lunch was waiting, and I discovered that Sadie had brought in some garbanzo bean soup with butternut squash that she had made a few days earlier. It was damn tasty, which is perhaps the most concise and accurate assessment I can offer. The soup had that comforting quality that makes a bowl of something warm particularly appealing in October, with the chickpeas providing substance, the butternut squash contributing a gentle sweetness, and the flavors coming together into something considerably more satisfying than the sum of its ingredients. Garbanzo beans, for anyone who prefers the name chickpeas, are excellent little legumes, rich in plant protein, dietary fiber, folate, and several minerals, while butternut squash brings its own contribution of carotenoids, which the body can use in the production of vitamin A. It was a good lunch from both a culinary and nutritional perspective, although I would be lying if I claimed to have spent much time contemplating its micronutrient profile while eating it. My principal concern was that it tasted good, and on that point, the soup passed with flying colors.

There is also something particularly pleasant about eating food that someone you love has prepared, especially when it arrives in the middle of an otherwise busy day. Hospital life can make meals feel transactional. You eat because you need to eat, often at whatever time the schedule permits, and sometimes while doing something else entirely. Sitting down with Sadie for a proper lunch offered a welcome change of pace, even if neither of us could pretend that we had escaped our professional responsibilities for very long. We talked, enjoyed the soup, and took advantage of a small window of time that might otherwise have disappeared into the day’s routine. Then, as happens with most pleasant interruptions during a workday, it was time to return to reality. I headed back to my office, where the afternoon’s appointments and follow-ups were waiting, and Sadie returned to her own responsibilities.

The remainder of the afternoon passed in much the same productive fashion as the morning. I worked through the remaining clinic appointments, addressed the follow-up issues that needed attention, and continued moving through the familiar assortment of clinical decisions and practical details that make up an ordinary day in surgery. There is always another chart to review, another question to answer, another plan to clarify, or another detail that needs to be settled before everyone can move on to the next task. None of this is especially dramatic, and that is precisely the point. Most of medicine consists not of spectacular rescues or extraordinary moments, but of hundreds of smaller decisions made carefully and consistently, with the hope that the cumulative result will be better care for the people who have entrusted us with their health.

By the time the clinic day approached its conclusion at 5:00 p.m., the light outside had begun to change. October afternoons have a way of reminding you that the year is moving forward whether you are paying attention or not. The sun was already beginning its descent, casting a softer, lower light across the hospital buildings, and the familiar landscape outside my office windows had taken on that late-afternoon appearance that makes the day feel nearly finished before the clock has quite caught up. I began the familiar ritual of packing up, shutting down the desktop computer, closing my laptop, and gathering the paperwork that needed to come home with me. I took off my white coat and put on my sports coat, making the small transition from physician at work to husband heading home. It is a simple change of clothing, but I have always liked the distinction. I spend my working hours in scrubs or a white coat, surrounded by the clinical machinery of a busy hospital, and there is something satisfying about putting on a proper jacket before walking out into the evening.

As I packed my bag, I found myself thinking about how much I enjoy that particular moment at the end of a good workday. Hospitals have a distinctive atmosphere, a persistent hum that seems to exist independently of the people moving through them. There are footsteps in the corridors, voices carrying from one room to another, telephones ringing, equipment beeping, conversations unfolding behind office doors, and the steady sense that somewhere in the building somebody is always doing something important. Even when the work has been productive and the day has gone well, there is a certain pleasure in stepping away from that environment and knowing that, for the moment, your responsibilities have been handed over, your immediate tasks are finished, and you can leave the building behind you.

I do not mean that I want to escape the work itself. Quite the opposite. I enjoy being a surgeon, and I appreciate the privilege of doing something that requires both intellectual engagement and practical skill. But there is a profound difference between enjoying one’s profession and allowing it to consume every available corner of one’s life. The best working days are often the ones that leave you with a sense of accomplishment rather than exhaustion, when you can look back at the hours behind you and feel that you have done something worthwhile without being entirely emptied by the process. Today was one of those days. I had seen my patients, addressed the issues that needed attention, enjoyed an unexpectedly excellent clinic, and managed to have lunch with my wife. There was little to complain about, and a great deal to appreciate.

I gathered my things, switched off the remaining lights, and headed out to the parking lot, where the BMW M8 was waiting. There are worse ways to end a workday than climbing into a comfortable performance car and heading home through the fading light of an October evening. The M8 is rather different from the quieter, more contemplative experience of driving the old Porsche 911SC, but it has a character all its own, with the sort of power and refinement that make an ordinary commute feel a little less ordinary. After spending the day in a hospital, where so much of one’s attention must be directed outward toward other people, there is something restorative about settling into the driver’s seat, starting the engine, and allowing the familiar routine of the drive home to take over. The hospital gradually recedes behind you, the traffic becomes part of the evening landscape, and your thoughts begin to drift away from the day’s appointments toward the more familiar concerns of home.

The drive back to Glocester is long enough to provide a useful transition between those two worlds. Boston has its own pace, its own density, and its own relentless sense of movement, while the countryside offers a different kind of space, one in which the roads eventually become quieter and the buildings give way to trees, fields, and the occasional farmhouse. I have made this commute often enough that I know its rhythms, and although the distance is not insignificant, the prospect of returning to the homestead makes the drive feel worthwhile. There is something appealing about leaving the clinical intensity of the city behind and heading toward a place where the evening might involve mowing the lawn, feeding the dogs, enjoying a home-cooked meal, or watching a film that has absolutely nothing to do with medicine.

When I pulled into the driveway, I arrived home only a little after Sadie, who had apparently beaten me there by a small margin. I came through the entrance and found her still dressed in her office attire, her purse hanging from her shoulder, while the dogs were busy welcoming her in the hallway with the sort of unrestrained enthusiasm that suggests they have been separated from their favorite people for several weeks rather than a normal working day. Bentley, our golden retriever, is particularly good at conveying the impression that your arrival is the most significant event to occur anywhere in the known universe. Davey, our German Shepherd, is not exactly reserved either. Between them, the hallway quickly became a flurry of tails, paws, noses, and excited movement, with both dogs making it abundantly clear that whatever we might have accomplished professionally during the day was of considerably less interest to them than the fact that we had returned home.

I barely had time to put my bag down before the dogs decided that I required an immediate and enthusiastic greeting of my own. There is a certain point at which trying to maintain a dignified entrance becomes futile, particularly when two large dogs have decided to conduct a full-scale inspection of your clothing and determine whether you have brought home any interesting smells from the outside world. I gave in to the inevitable, got the dogs organized, and took them outside. The moment the door opened, they were off, delighted to be released into the familiar territory of the property, where the world was considerably more interesting than anything that might have happened in a hospital office.

While the dogs explored, I caught sight of Sadie and Schnitzel watching us from the window. Sadie was smiling, clearly amused by the spectacle unfolding outside, while Schnitzel, our orange tabby, was regarding the entire operation with an expression of profound disapproval. Cats have a remarkable talent for making ordinary circumstances look like a personal affront. Schnitzel is particularly skilled at it. He can sit perfectly still, look directly at you, and somehow communicate that your existence has fallen well below his expectations. There was Sadie, enjoying the sight of the dogs running around outside, and then there was Schnitzel, who appeared to be conducting an internal review of my behavior and finding the results unsatisfactory. I have no doubt that he considers himself the senior authority in the household, and he may well be correct. The dogs might be considerably larger, but the cat has the advantage of never having felt the need to seek anyone’s approval.

Once the dogs had been outside for a little while, I decided that since I was already out in the fresh air, I might as well make use of the remaining daylight and get ahead on the lawn. October is an awkward month for outdoor chores. There is still enough growing season left that the grass cannot be entirely ignored, but the days are getting shorter, and the window for finishing the work before darkness falls seems to close a little earlier every evening. I took the mower out and started on the front and side lawns, figuring that I could leave the backyard for another day. There is always another task waiting on a property like ours, particularly when you have fields, gardens, trails, woods, and the various other responsibilities that come with maintaining a sizeable piece of rural land. One can spend an entire afternoon working outside and still find enough to do tomorrow to justify getting up early again.

That is part of the appeal of living here, though. The property requires work, certainly, but the work comes with its own rewards. There is a tangible satisfaction in looking back across a lawn you have just cut, seeing the clean lines and the orderly appearance of the grass, and knowing that you have accomplished something that does not require a computer, a committee, or a password reset. The lawn does not care about administrative meetings, and the mower is refreshingly indifferent to the latest changes in hospital documentation requirements. You start it, guide it across the grass, and gradually turn an untidy stretch of ground into something a little more presentable. It is straightforward, physical work, and after a day spent thinking through clinical problems, I find that sort of activity can be surprisingly relaxing.

As the mower moved across the front and side lawns, the evening air felt particularly pleasant. The temperature had climbed a little from the early morning chill, and the countryside was settling into the slower pace that comes with the end of the day. The trees stood along the edges of the property, the pond lay beyond the yard, and the dogs continued their patrol of the grounds, investigating whatever had happened in their absence. Every so often, I could see them moving through the grass or disappearing toward the familiar paths that led down toward the water. They seemed entirely content with their responsibilities, which presumably consist of monitoring the property, sniffing things that do not need sniffing, and ensuring that no squirrel is allowed to move about without proper supervision.

Eventually, I decided that the front and side lawns were sufficient for one evening and put the mower away. The backyard could wait. There is a useful lesson in recognizing when enough is enough, although it is one that people in demanding professions sometimes have to learn repeatedly. There will always be another task to complete, another improvement to make, or another reason to extend the working day by another half hour. Yet one of the advantages of living somewhere with so much outdoor space is that the work will still be there tomorrow, and there is no particular virtue in treating every ordinary household responsibility as an emergency. The grass would survive the night, the backyard would remain uncut, and the world would continue turning without my intervention.

I spent a little longer outside, enjoying the fresh air and allowing the dogs to roam before we eventually made our way back into the house. By then, Sadie had already showered and was apparently well ahead of me in the transition from working professional to comfortable evening at home. I headed upstairs for my own shower, grateful to wash away the dust, the day’s accumulated fatigue, and whatever traces of the hospital and lawn work had decided to accompany me. There is something deeply satisfying about a shower at the end of a day like this, particularly after a morning jog and an evening spent working outside. The warm water seems to mark a boundary between the responsibilities that have already been handled and the hours that remain, which belong to a different and considerably more pleasant category of life.

When I came downstairs, the kitchen smelled wonderful. Sadie was already working on dinner, and the familiar aromas drifting through the house made it clear that the evening’s meal was going to be considerably more interesting than whatever I might have managed to assemble for myself. I sat down at the kitchen table, opened my laptop, and began looking for something to watch later while she finished cooking. This is one of the little domestic rituals I particularly enjoy. Sadie has a remarkable ability to turn an ordinary evening into something that feels special without making an elaborate production of it, and I have learned that when she is in the kitchen preparing dinner, it is generally wise to let her work and simply appreciate the results. I can contribute by setting the table, cleaning up afterward, or locating an appropriate film, which is a division of labor I am perfectly willing to defend.

Dinner had an Irish character tonight, as Sadie prepared boxty with smoked salmon, accompanied by a mash of parsnips and carrots. Boxty is a traditional Irish potato pancake, with regional and family variations in how it is prepared, and it is the sort of dish that makes considerable sense once the weather begins turning cooler. Potatoes provide the foundation, while the smoked salmon brings a savory richness and the parsnip-and-carrot mash contributes sweetness and an earthy depth that complements the rest of the meal. It is hearty without being unnecessarily heavy, and it has the sort of rustic comfort that seems particularly appropriate for an October evening in New England, when the darkness comes early and the prospect of sitting down to a warm dinner becomes increasingly attractive.

I have always appreciated the way food can make a place feel like home. It is not merely a matter of eating well, although that certainly helps. A good meal has a way of gathering the day’s scattered pieces into a coherent whole. You have spent the morning and afternoon dealing with professional responsibilities, driven home through traffic, entertained the dogs, worked on the lawn, and showered, and suddenly you are sitting at your own table with someone you love, enjoying a meal that was prepared in your own kitchen. The day’s demands have not disappeared, and tomorrow will bring another round of appointments, decisions, and obligations, but for the moment there is no particular reason to be anywhere else. The food is good, the company is familiar, and the evening is unfolding at its own pace.

After dinner, we cleared the table and put the dishes into the dishwasher, taking care of the small tasks that make the kitchen ready for the next morning. It is hardly the sort of activity that would attract much attention in a travel magazine or a glossy feature about country living, but it is part of the ordinary structure of a household. The dishes do not wash themselves, the counters need wiping, and the kitchen must be put back in order before everyone retreats to the living room. I rather like the simple satisfaction of finishing those tasks. A clean kitchen at the end of the evening means one less thing to confront when the alarm sounds at four in the morning, and anything that makes the early start marginally less complicated is worth doing.

Our entertainment plans for tonight are particularly well suited to the sort of evening we have in mind. We are beginning with Waterworld, the 1995 science-fiction adventure starring Kevin Costner, before rounding things off with Close Encounters of the Third Kind, Steven Spielberg’s 1977 film about humanity’s encounter with something beyond our ordinary understanding of the universe. It is an interesting pairing, even if the two films approach their subject matter from rather different directions. Waterworld imagines a future in which the polar ice caps have melted and the planet has become an enormous expanse of water, leaving humanity to survive on makeshift settlements and vessels while searching for the increasingly elusive possibility of dry land. Close Encounters, by contrast, begins with the familiar world and gradually opens a door into something much stranger, asking what might happen if the universe suddenly ceased to be an abstraction and became an unmistakable presence in our lives.

I have a soft spot for these sorts of movie nights because they allow us to revisit films without the obligation to take them too seriously. Some movies are best enjoyed as technical achievements, others as works of art, and still others as gloriously imperfect entertainment that becomes more enjoyable when you stop worrying about whether every plot point survives close examination. Waterworld has certainly accumulated its share of discussion over the years, not least because of its famously troubled production and the extravagant scale of its ambitions, but there is something appealing about its strange, waterlogged vision of the future. It has boats, improvised societies, villains, survival, and the stubborn human desire to find somewhere better than the place in which we currently find ourselves. That is enough material for an entertaining evening, especially when the alternative is spending the night reading administrative correspondence.

And then there is Close Encounters of the Third Kind, which belongs to a different era of science fiction, one in which the possibility of extraterrestrial life could be approached with genuine wonder rather than simply as an excuse for the next spectacular battle. Spielberg’s film understands that the unknown can be unsettling without necessarily being hostile, and that sometimes the most compelling response to an extraordinary mystery is curiosity. There is something almost old-fashioned about its willingness to let a story unfold gradually, allowing the audience to sit with uncertainty while the characters attempt to make sense of what they have witnessed. It is a film that invites you to look upward, to consider how much of the universe remains beyond our understanding, and to wonder whether the things we dismiss as impossible might simply be things we have not yet learned how to explain.

Perhaps that is part of why these older films remain so enjoyable. They belong to periods when science fiction could be ambitious, peculiar, and occasionally ridiculous without needing to apologize for any of those qualities. They can be products of their time while still retaining the ability to entertain us decades later, and watching them at home offers the pleasure of revisiting an earlier chapter of popular culture without having to pretend that everything made in the past was automatically better. Some films age beautifully, some become fascinating historical artifacts, and some simply remain fun. A good movie night does not require every selection to be a masterpiece. It requires only that the films be enjoyable, the company be good, and the evening provide a welcome alternative to the demands of the outside world.

Of course, there is one more consideration when planning an evening of movies at our house, and that is the likelihood that Bentley and Davey will eventually decide to join us. They are currently outside again, roaming around the property near the pond, presumably carrying out whatever important canine business has occupied their attention throughout the day. Given their habits, I expect they will eventually make their way indoors and establish themselves in the living room, where they will settle down with the comfortable entitlement of animals who are entirely convinced that every piece of furniture exists for their benefit. Bentley will probably find a position that allows him to occupy more space than seems physically reasonable for one dog, while Davey will conduct a brief survey of the room before choosing his preferred place to lie down. Neither will have the slightest interest in the plot of Waterworld, but both will undoubtedly expect to be included in the evening’s arrangements.

Schnitzel, meanwhile, remains a separate and rather more complicated matter. As I write this on my laptop at the kitchen table, he is sitting nearby and staring at me with the same expression of quiet condemnation he displayed from the window earlier. I cannot say with certainty what he wants, but experience suggests that the possibilities include food, attention, a door opened for no apparent reason, a door closed immediately afterward, or the opportunity to interrupt whatever I happen to be doing simply because he has decided that I have been occupied for long enough. Cats are experts at making their wishes known without offering any useful explanation of what those wishes might be. Schnitzel is particularly adept at this form of domestic negotiation, and I suspect that he will eventually make his presence felt during the movies, perhaps by walking directly across the laptop, settling on the most inconvenient part of the sofa, or positioning himself between us and the television as though he has personally purchased the broadcasting rights.

I would not be surprised if he eventually decides that the living room belongs exclusively to him and that our plans for an evening of science fiction are a regrettable intrusion into his private affairs. The dogs, at least, are comparatively straightforward. They want to be near us, they enjoy being outside, and they are generally satisfied as long as they have room to stretch out and someone occasionally scratches behind their ears. Schnitzel operates according to a more sophisticated set of principles, most of which appear to have been developed specifically to remind the rest of the household that affection is a privilege he grants rather than a service he provides. He is an excellent cat, but I have no intention of suggesting that he is an easy one to impress.

Looking back over the day, what strikes me most is how satisfying an ordinary Thursday can be when its various pieces fall into place. There was the early morning jog in the cool October air, the quiet routine of breakfast, the hospital rounds before clinic, and a productive day spent seeing patients and working through their follow-up care. There was lunch with Sadie, made better by a bowl of homemade garbanzo bean and butternut squash soup, followed by an afternoon that passed quickly and left me with a genuine sense of accomplishment. Then came the drive home in the M8, the enthusiastic welcome from the dogs, the sight of Sadie and Schnitzel watching from the window, a little work on the lawn, a shower, and a dinner that could have come from a comfortable country kitchen somewhere in Ireland. None of those events would qualify as extraordinary on its own, but together they make up the texture of a life that I am grateful to have.

It is easy, particularly in demanding professions, to become preoccupied with the next thing that needs to be done. Medicine encourages a forward-looking mentality because patients require attention, problems need solutions, and the consequences of inattention can be serious. There is always another case, another clinic, another set of rounds, another responsibility waiting just beyond the horizon. Running a household on a rural property adds its own collection of obligations, from maintaining the lawns to keeping the house in order and making sure the dogs have enough time outside. Yet I think there is considerable value in occasionally recognizing that a day has been good without needing it to have been extraordinary. A productive clinic, a pleasant lunch with your wife, a little fresh air, a home-cooked dinner, and the prospect of a couple of enjoyable films are not insignificant things simply because they are familiar.

In fact, familiarity may be part of what makes them valuable. The routines we build together are often the things that hold our lives steady when the rest of the world becomes unpredictable. Sadie and I have our morning jogs, our workdays, our meals, our evenings at home, and our collection of small rituals that have accumulated over the years. We have the dogs who greet us as though we have returned from an expedition, the cat who believes he is responsible for maintaining standards, and a property that provides an endless supply of outdoor work whenever we need a reminder that the physical world is not impressed by professional titles. There are lawns to cut, dishes to wash, meals to prepare, and movies to watch. It is an uncomplicated list, perhaps, but it is a good one.

Tomorrow will bring another early alarm, another morning jog if the weather cooperates, another breakfast, and another drive toward Boston. There will be patients to see, decisions to make, and whatever unexpected complications the day decides to introduce. Perhaps the clinic will be busy, perhaps the hospital will have other plans for me, and perhaps some issue will arise that requires more attention than I would prefer to give it. That is simply the nature of the work, and there is little point in pretending otherwise. But tonight, the immediate responsibilities have been handled, the front and side lawns have been cut, the kitchen has been cleaned, and dinner has been enjoyed. The dogs are still outside near the pond, Schnitzel is continuing his silent campaign to obtain my attention, and somewhere in the living room there is a television waiting to bring us a dystopian ocean, a mysterious musical signal, and a couple of hours of welcome escapism.

For now, that is more than enough. I will finish writing, give the cat whatever attention he has decided I owe him, and join Sadie for our movie night. Tomorrow can take care of itself when tomorrow arrives, which is not an entirely bad philosophy for a Thursday evening in October. After all, there will always be another clinic, another lawn to mow, another meal to enjoy, and another film worth revisiting. The trick is remembering to appreciate the day you have actually lived rather than spending every waking hour preparing for the one that comes next.

Probiotics and ADHD: Can the Gut Help the Developing Brain?

There was a time when the idea that bacteria living in the gastrointestinal tract could influence a child’s behavior would have sounded more like science fiction than medicine. We thought of the intestine primarily as the place where food was digested and nutrients were absorbed, while the brain was treated as an entirely separate organ system with its own problems and diseases. We now know that this division is far too simplistic. The gastrointestinal tract and the brain are in constant communication through neural, hormonal, immune and metabolic pathways, and the enormous community of microorganisms living within the intestine participates in that conversation.

That brings me to an interesting clinical trial involving children with attention-deficit/hyperactivity disorder, or ADHD. Researchers recently investigated whether daily supplementation with a combination of three probiotic organisms, Lactobacillus acidophilus, Bifidobacterium lactis and Bifidobacterium longum, could influence executive function in children with ADHD. Eighty-four children between 7 and 12 years old participated in the triple-blind randomized controlled trial. They received either the probiotic preparation or a placebo every day for two months. Importantly, the children were already receiving stable methylphenidate treatment, meaning the investigators were studying the probiotic as an adjunct, not as a replacement for established ADHD therapy.

The results were striking enough to deserve attention. After two months, children receiving the probiotic preparation demonstrated a significant improvement in global executive function compared with those receiving placebo. The researchers concluded that probiotics might have a role as a non-pharmacologic adjunctive therapy for improving executive function in children with ADHD, although they also emphasized the need for larger studies, longer follow-up and more objective neuropsychological testing.

That last qualification is important. This is interesting research. It is not a reason to throw away a child’s ADHD medication and replace it with a bottle of bacteria.

ADHD Is About More Than Paying Attention

ADHD is often described casually as a disorder in which a child cannot sit still or pay attention. That description is incomplete.

ADHD is a neurodevelopmental disorder characterized by persistent patterns of inattention and/or hyperactivity and impulsivity that interfere with functioning. Depending upon the child, the problem may manifest as difficulty sustaining attention, excessive activity, impulsive behavior, disorganization, forgetfulness, poor time management or difficulty completing tasks. The consequences can extend into school performance, family relationships, friendships and eventually employment and other areas of adult life.

One of the most interesting aspects of ADHD is its relationship with executive function.

Executive function is not a single ability. It is a collection of higher-order cognitive processes that allow us to organize behavior toward a goal. Working memory allows us to hold information in our minds while manipulating it. Inhibitory control helps us resist an immediate response when a different response would be more appropriate. Cognitive flexibility allows us to change strategies when circumstances change. Planning, organization, problem solving and self-monitoring all depend to varying degrees on executive processes.

Think about what a child is actually being asked to do during an ordinary school day. The child has to remember the teacher’s instructions, resist the urge to interrupt, organize the materials necessary to complete an assignment, shift from one subject to another, estimate how much time remains and continue working even when the task is not particularly interesting.

Those are executive functions.

A child can be intelligent and understand the material perfectly well while still struggling to consistently deploy those abilities.

What the Researchers Actually Found

The study used the Behavior Rating Inventory of Executive Function, or BRIEF, completed by parents. The global executive composite score in the probiotic group improved substantially after the two-month intervention, while the placebo group showed essentially no change. The difference remained significant after the researchers adjusted for age, body mass index and IQ.

This is an encouraging finding, but there is an important detail hiding in the methodology: the primary assessment was a parent-rated behavioral questionnaire.

That does not make the finding unimportant. Parents observe children in circumstances that laboratory testing cannot reproduce, and the BRIEF is a well-established instrument for assessing executive-function behaviors. But subjective behavioral ratings are different from objective neuropsychological performance tests. A larger future trial incorporating computerized attention testing, working-memory testing, inhibitory-control measures and formal neuropsychological assessments would give us a much stronger answer.

The authors themselves recognized this limitation and called for further studies using objective neuropsychological evaluations and longer follow-up.

That is exactly what I would want to see next.

Why Would a Probiotic Affect Executive Function?

This is where the biology becomes fascinating.

The intestine and brain communicate through what is commonly called the gut-brain axis. The term sounds fashionable, but the underlying physiology is real. Signals travel between the gastrointestinal tract and central nervous system through the vagus nerve, endocrine pathways, immune signaling and microbial metabolites.

The microbiome is also metabolically active. Intestinal microorganisms ferment components of our diet, particularly certain forms of dietary fiber, producing short-chain fatty acids such as acetate, propionate and butyrate. These molecules can influence intestinal barrier function, immune signaling and metabolism. Microorganisms can also influence pathways involved in neurotransmitter production and regulation.

The vagus nerve provides another communication route. It carries information in both directions between the gastrointestinal tract and brainstem. Changes in the intestinal environment can therefore influence neural signaling without requiring bacteria themselves to travel anywhere near the brain.

The immune system provides yet another connection. The intestinal tract contains an enormous amount of immune tissue, and the microbiome helps regulate the relationship between the intestinal contents and the immune system. Alterations in the microbial environment may influence inflammatory signaling, although the relationship is complicated and we are still determining what constitutes a clinically meaningful change.

This creates a plausible biological framework for the idea that altering the intestinal microbiome could influence aspects of cognition and behavior.

Plausibility, however, is not proof.

That distinction is one of the most important principles in medicine.

The Microbiome Is Not a Light Switch

It is tempting to think of the microbiome as a collection of “good bacteria” and “bad bacteria,” as though we could simply add enough good organisms and restore everything to normal.

Human microbiology is considerably more complicated.

The intestinal microbiome consists of a vast ecosystem containing bacteria, fungi, viruses and other microorganisms. Different organisms compete, cooperate and respond to dietary substrates and the surrounding environment. The composition of the microbiome varies from person to person and changes over time.

Diet matters. Antibiotics matter. Age matters. Illness matters. Medications matter. Geography and lifestyle matter.

And importantly, putting a bacterial strain into the gastrointestinal tract does not guarantee that it will permanently colonize the intestine.

A probiotic may transiently influence the intestinal environment without establishing itself as a permanent member of the microbiome. That may be sufficient to produce a biologic effect, or it may not. We still have a great deal to learn about what happens after a person stops taking the supplement.

Three Bacteria, Not “Probiotics” in General

Another point I would emphasize to patients is that the word probiotic is far too broad to be clinically useful by itself.

The trial did not demonstrate that every probiotic on the market improves executive function in children with ADHD. It studied a particular combination of Lactobacillus acidophilus, Bifidobacterium lactis and Bifidobacterium longum. Even within those species, individual strains can have different biological properties.

That distinction matters enormously.

We would never conduct a clinical trial using three specific antibiotics and then conclude that “antibiotics treat pneumonia” without specifying the drugs, doses, organisms and circumstances. Probiotics deserve the same scientific precision.

A bottle containing a dozen bacterial species is not necessarily equivalent to the formulation used in this study. A product containing 50 billion organisms is not automatically better than one containing 5 billion. The number of organisms is only one characteristic of the preparation.

What matters is whether the specific organism or combination has evidence supporting the particular clinical outcome we are interested in.

What About the ADHD Symptoms Themselves?

This is where the current evidence becomes considerably less convincing.

The 2026 trial primarily demonstrated improvement in executive-function behavior, not proof that probiotics eliminate the core symptoms of ADHD.

And that distinction is supported by earlier research.

A 2024 meta-analysis examined seven randomized trials involving 379 children and adolescents and found no statistically significant overall improvement in total ADHD symptoms, inattention, or hyperactivity/impulsivity with probiotics compared with placebo. The investigators did note that some subgroups appeared more promising, particularly studies involving multiple probiotic strains or probiotics used alongside methylphenidate, but those subgroup findings were not statistically definitive. The certainty of the evidence was considered low or very low.

That is a very different conclusion from saying that probiotics treat ADHD.

In fact, I think the contrast makes the new study more interesting rather than less interesting.

Perhaps the microbiome is influencing particular aspects of cognition or executive behavior without producing a large enough effect to change the entire clinical syndrome. Or perhaps the apparent improvement in executive function will not hold up when larger, more rigorous trials are performed.

We do not know yet.

There Are Other Encouraging Studies

The new trial is not the first investigation to find a possible relationship between probiotics and cognitive or behavioral measures in children with ADHD.

A randomized clinical trial involving 80 children and adolescents studied Lactobacillus acidophilus LB as an adjunct to atomoxetine. After 12 weeks, the probiotic group demonstrated improvements in some parent-rated ADHD and behavioral measures as well as certain measures of attention and executive performance compared with the control group.

Another randomized trial published in 2024 studied Bifidobacterium bifidum as an add-on treatment in children already receiving stable methylphenidate. After 12 weeks, the probiotic group demonstrated improvements in certain computerized attention measures, including omission errors and reaction time. Investigators also observed changes in aspects of the gut microbiome.

These studies are intriguing because several are pointing in a similar direction, but they are not identical studies and they used different organisms, doses, outcome measures and ADHD medications.

That makes it impossible to say that there is now a single established probiotic treatment for ADHD.

Why Might the Gut and Brain Be Connected in ADHD?

Researchers have proposed several mechanisms.

One possibility involves inflammatory signaling. Some studies have reported differences in inflammatory markers or immune signaling among people with ADHD, although these findings are not sufficiently consistent to define ADHD as an inflammatory disorder.

Another possibility involves microbial metabolites. The organisms living in the intestine metabolize dietary components and produce compounds that can influence host metabolism and potentially neural signaling.

There is also interest in neurotransmitter pathways. The gut microbiome can interact with biochemical pathways involving serotonin, dopamine, GABA and other signaling molecules. Dopamine, of course, is particularly relevant to ADHD because dopaminergic signaling plays an important role in attention, motivation and executive control.

But here again, we have to resist the temptation to turn a complicated biological pathway into a simplistic explanation.

It would be incorrect to say that a probiotic “increases dopamine in the brain” and therefore treats ADHD. The actual physiology is considerably more complex, and evidence demonstrating that a probiotic produces a clinically meaningful alteration in central dopaminergic neurotransmission in children with ADHD remains limited.

This Is Not an Alternative to Stimulant Medication

This is probably the most important practical point.

If a child has clinically significant ADHD and is benefiting from methylphenidate or another evidence-based treatment, I would not advise the family to discontinue medication because a probiotic study produced an interesting result.

The new study specifically examined probiotics in children who were already receiving stable methylphenidate therapy. In other words, the investigators were asking whether probiotics could potentially add something to existing treatment. They were not demonstrating that probiotics could replace methylphenidate.

That is what the phrase adjunctive therapy means.

In medicine, adjunctive means something added to the primary treatment rather than substituted for it.

The distinction may seem obvious, but it is frequently lost when research findings are translated into headlines.

ADHD Treatment Is Bigger Than a Pill

At the same time, it is important not to reduce ADHD treatment to medication alone.

Depending on the child’s age and circumstances, treatment may include behavioral interventions, parent training, school-based accommodations, organizational strategies, psychotherapy when appropriate, medication and attention to sleep, nutrition and other medical conditions that can worsen symptoms.

School accommodations can be particularly important. A child who struggles with executive function may benefit from organizational support, breaking large assignments into smaller components, clear written instructions, predictable routines and additional time when appropriate.

These interventions do not “cure” ADHD, but they can reduce the functional consequences of the disorder.

And this is another reason the new probiotic research is interesting. Executive function is precisely the area in which many children with ADHD experience practical difficulties. If future trials demonstrate that particular probiotic preparations can reliably improve executive functioning, they could potentially become one component of a broader treatment strategy.

But we are not there yet.

What Should Parents Do With This Information?

If I were talking with a parent in the office, I would first tell them that the research is promising but preliminary.

I would not recommend grabbing the first probiotic marketed for children with ADHD. The study used a specific three-strain combination, and the evidence does not establish that every commercial probiotic produces the same effect.

I would also want to know what other treatment the child is receiving, whether the ADHD diagnosis has been appropriately established, whether there are sleep problems, whether there are gastrointestinal symptoms and whether the child has other medical conditions or takes other medications.

If a family is interested in trying a probiotic, that is a reasonable conversation to have with the child’s pediatrician or ADHD clinician. A probiotic is generally well tolerated in otherwise healthy children, but supplements are not completely risk-free, particularly in children who are medically fragile or significantly immunocompromised.

And I would keep expectations realistic.

We are talking about a potential modest adjunctive intervention, not a cure.

The Bigger Question Is More Interesting Than the Supplement

What fascinates me most about this research is not actually the probiotic capsule.

It is what the study says about how we think about the human body.

For generations, we treated the gastrointestinal tract as essentially a digestive machine. We now understand that it is an extraordinarily sophisticated organ involved in immune regulation, endocrine signaling, metabolism and neural communication. Its microbial ecosystem is not simply along for the ride. It participates in biochemical processes that affect the host.

The brain, meanwhile, is not isolated from the rest of the body.

The immune system talks to it. Hormones talk to it. Metabolic signals talk to it. The vagus nerve talks to it. And, apparently, the microbial ecosystem living in our intestine may have something to say as well.

That does not mean that every problem involving the brain can be solved by changing the microbiome. It means that the old boundaries we drew between organ systems are becoming increasingly difficult to defend biologically.

The Research Needs to Grow Up Before We Change Practice

The new trial has several strengths. It was randomized, triple-blinded and placebo-controlled, and it included children with established ADHD who were receiving stable methylphenidate therapy. Those are meaningful strengths.

But it was still only 84 children, the intervention lasted only two months, and the primary outcome was based on a parent-completed executive-function questionnaire. The investigators appropriately called for larger studies, longer follow-up and objective neuropsychological testing.

That is exactly what should happen next.

I would like to see multicenter trials with substantially larger numbers of children, standardized probiotic strains and doses, objective cognitive testing, standardized ADHD symptom measurements and follow-up extending well beyond eight weeks. It would also be valuable to know whether the effects persist after supplementation stops, whether particular children respond better than others, and whether baseline microbiome characteristics can predict response.

Ultimately, we need to know whether improving an executive-function test translates into what parents and teachers actually care about: better school performance, better organization, fewer disruptive behaviors, improved relationships and better day-to-day functioning.

Those are the outcomes that matter.

A Promising Idea, Not a Finished Treatment

There is a tendency in medicine to swing between two extremes whenever a new study appears. One group sees a promising result and declares that we have discovered the next breakthrough. Another dismisses the entire field because the evidence is not yet definitive.

Neither response is particularly useful.

The more reasonable interpretation is that this is an intriguing piece of evidence in a developing field.

A carefully selected combination of Lactobacillus acidophilus, Bifidobacterium lactis and Bifidobacterium longum was associated with significant improvement in parent-rated executive function after two months in children with ADHD who were already receiving stable methylphenidate treatment. That is worth knowing.

At the same time, broader evidence has not established probiotics as an effective treatment for the core symptoms of ADHD, and previous meta-analysis has found no significant overall benefit for inattention, hyperactivity or impulsivity.

Both findings belong in the same conversation.

For now, I would consider probiotics an interesting area of adjunctive research, not a replacement for established ADHD treatment. The gut-brain axis is increasingly convincing as a biological concept, but we are still learning exactly how much influence the microbiome has over cognition and behavior, which bacterial strains matter, which children might benefit and how durable those effects are.

The intestine may indeed have a conversation with the developing brain.

We just have not finished figuring out what they are saying to each other.

Probiotics and the Brain: Can a Healthier Gut Help Keep the Mind Sharp?

For years, when we talked about probiotics, the conversation was almost entirely about the gastrointestinal tract. We thought about yogurt, kefir, fermented foods, diarrhea after antibiotics and the general idea of keeping the intestinal microbiome healthy. The brain seemed like an entirely different subject. After all, what possible connection could there be between the bacteria living in the intestine and the ability to remember someone’s name, solve a problem, process information or find your way around a familiar place?

As it turns out, the connection may be considerably more interesting than we once appreciated.

A new meta-analysis examining probiotic supplementation and cognitive function across the human lifespan found evidence that probiotics may have favorable effects on several aspects of cognition, with the most consistent benefits appearing among older adults. The researchers found improvements in overall cognitive performance, information-processing speed, memory and spatial ability in older people. They also found improvements in executive function among infants and children and an improvement in verbal ability among young adults. The strongest effects in older adults were observed after approximately 12 weeks of daily supplementation. The paper, “Effects of probiotics on cognitive function across the human lifespan: a meta-analysis,” was published in the European Journal of Clinical Nutrition in 2026 and included 21 randomized controlled trials.

That is an interesting finding, but it needs to be handled with some restraint. We are nowhere near the point where I would tell a patient that a probiotic capsule will prevent Alzheimer’s disease or preserve memory into old age. The human brain is far too complicated for that kind of claim. What the research does suggest, however, is that the gastrointestinal tract and the brain communicate in ways that may be clinically meaningful, and probiotics could potentially influence some of those pathways.

In medicine, those are the findings that are worth paying attention to.

The Gut and the Brain Are Not Separate Systems

The term gut-brain axis has become increasingly common in medical literature, and it describes a genuine biological communication network rather than a catchy phrase invented by the supplement industry.

The gastrointestinal tract communicates with the central nervous system through several overlapping pathways. The vagus nerve provides a major neural connection between the intestine and brain. Hormones and other signaling molecules released from the gastrointestinal tract enter the circulation and influence distant tissues. The immune system provides another communication pathway, because the intestinal microbiome interacts continuously with immune cells and inflammatory signaling. Microorganisms in the intestine also metabolize dietary components into biologically active compounds, including short-chain fatty acids, that can influence physiology beyond the gut.

The brain, meanwhile, does not simply sit passively at the receiving end of this communication. It influences gastrointestinal motility, secretion, blood flow and immune activity through the autonomic nervous system and neuroendocrine pathways.

This is a two-way conversation.

Stress can alter intestinal motility. Illness can change the microbiome. Diet can change which microorganisms flourish. Medications can alter the microbial environment. The microbial environment can, in turn, influence immune signaling and metabolism. Once you begin looking at the gastrointestinal tract this way, the idea that intestinal health might have some relationship to brain function becomes considerably less surprising.

What Exactly Is a Probiotic?

A probiotic is a live microorganism that, when administered in adequate amounts, provides a health benefit to the host. That definition is important because not every bacterium found in yogurt, fermented food or a supplement qualifies as a probiotic in the scientific sense.

The word “probiotic” also encompasses an enormous variety of organisms. Common probiotic genera include Lactobacillus and Bifidobacterium, although bacterial taxonomy has become considerably more complicated as scientists have reclassified many species. Different strains can behave differently, which means that one probiotic cannot automatically be assumed to have the same effects as another.

This is one of the problems with the supplement aisle.

A bottle may proudly announce that it contains 20 billion, 50 billion or even 100 billion colony-forming units, but a larger number does not automatically mean a better product. The specific organism, strain, dose, formulation, viability and clinical evidence behind that particular preparation all matter.

Medicine generally asks, “What drug, at what dose, for which patient, for what condition?” We should ask probiotics essentially the same questions.

Why Would Bacteria Affect the Brain?

There are several plausible mechanisms.

One involves the production of microbial metabolites. Intestinal bacteria ferment certain components of our diet, particularly fiber, producing short-chain fatty acids such as acetate, propionate and butyrate. These compounds participate in metabolic and immune signaling and may influence the intestinal barrier and inflammatory responses.

Another pathway involves the immune system. The intestine contains an enormous proportion of the body’s immune activity, and the microbiome helps regulate the relationship between the intestinal environment and immune cells. Disruption of the microbiome can influence inflammatory signaling, although the relationship is complicated and varies considerably among individuals.

There is also the vagus nerve. Signals generated in the gastrointestinal tract can influence the brain through vagal pathways, providing a rapid communication route between the two organs.

And then there are neurotransmitter-related pathways. Some intestinal microorganisms can produce or influence compounds involved in neurochemical signaling, including metabolites related to serotonin, GABA and other pathways. This does not mean that eating a probiotic bacterium is equivalent to taking an antidepressant or a neurologic medication. It means that the microbiome participates in a much larger biochemical ecosystem than we once appreciated.

The important point is that we do not yet know which of these mechanisms is responsible for the cognitive findings observed in clinical trials, and it is entirely possible that several mechanisms are operating simultaneously.

Why Might Older Adults Benefit the Most?

The findings in older adults are particularly interesting.

As we age, the gastrointestinal microbiome changes. Diet, medications, chronic diseases, reduced physical activity and changes in gastrointestinal physiology can all influence microbial diversity and composition. Older adults also have greater baseline risks of chronic inflammation, metabolic disease and cognitive impairment.

That creates an interesting possibility: perhaps modifying the intestinal environment has a greater measurable effect when some of the systems involved are already under physiological stress.

The 2026 meta-analysis found that older adults experienced significant improvements in overall cognitive performance, processing speed, memory and spatial ability. The effect sizes were statistically significant in each of these domains, with memory showing one of the strongest associations. The investigators also found that approximately 12 weeks of daily supplementation appeared to produce the best results, with a dose around 20 billion colony-forming units per day associated with the strongest findings in their analysis.

But I would be careful about turning that number into a prescription.

The fact that the studies in the meta-analysis produced their best results around a particular dose does not mean that every healthy older adult should walk into a store and purchase a probiotic containing exactly 20 billion organisms. The strains and formulations varied among studies, and the optimal dose has not been established as a universal standard.

Memory Is Particularly Interesting

Memory is one of the cognitive domains that understandably generates the most interest among older adults.

There is a tremendous difference between ordinary age-related changes in memory and pathological cognitive decline. Forgetting where you left your glasses occasionally is not the same thing as losing the ability to manage finances, prepare meals or navigate familiar surroundings. Cognitive impairment is a clinical syndrome, and dementia represents a substantial decline in cognitive function that interferes with everyday life.

The probiotic research does not establish that probiotics prevent dementia.

What it suggests is that certain probiotic interventions may produce measurable improvements on cognitive testing in some populations. That is interesting, but it is not the same claim.

In fact, other recent meta-analyses have produced more cautious conclusions. A 2025 meta-analysis of 34 randomized trials involving 2,390 adults found possible improvements in several cognitive measures after approximately 12 weeks, but the investigators rated the certainty of the evidence as low or very low. Another meta-analysis specifically examining 20 randomized trials in older adults found a positive trend but substantial heterogeneity between studies, making it difficult to establish a single reliable effect size.

That is exactly the kind of scientific disagreement I would expect from an emerging field.

What About Children?

The lifespan findings become even more interesting when we move to the other end of life.

The 2026 meta-analysis found that probiotic supplementation was associated with improved executive function in infants and children. Executive function encompasses a collection of cognitive abilities involved in planning, working memory, inhibitory control, attention and problem solving. These are fundamental skills for childhood development.

Again, we should not interpret this as proof that every child needs a probiotic supplement.

Childhood cognition is influenced by nutrition, sleep, physical activity, education, socioeconomic circumstances, family environment, genetics, illness and countless other factors. A probiotic cannot compensate for chronic sleep deprivation or inadequate nutrition, nor should a supplement ever become a substitute for appropriate pediatric care.

The finding is nevertheless biologically intriguing because childhood is a period of enormous neurologic development, and the intestinal microbiome itself undergoes substantial changes during early life. Researchers are increasingly interested in whether the microbiome participates in developmental processes involving the immune system and nervous system.

That field is still developing, but it is certainly worth watching.

And Then There Are Young Adults

Young adults appeared to have a somewhat different response. In the meta-analysis, probiotic supplementation was associated primarily with improvements in verbal ability. The investigators did not find the same broad pattern of cognitive improvement observed in older adults.

That difference across age groups is important because it suggests that probiotics are not simply functioning as a universal cognitive enhancer.

If they were a general-purpose brain stimulant, we would expect essentially the same cognitive effect regardless of age. Instead, the findings appear to vary according to the developmental stage and perhaps the physiological condition of the individual.

That makes the biology considerably more interesting.

The Microbiome Is Not a Permanent Organ

One of the misconceptions surrounding probiotics is that we have a fixed collection of “good bacteria” that simply needs to be replenished whenever we lose them.

The microbiome is considerably more dynamic.

Diet, medications, illness, geography, age and lifestyle can all influence its composition. Antibiotics can dramatically alter microbial populations, sometimes for prolonged periods. Dietary fiber provides substrates for microbial fermentation. Different microorganisms compete with one another for nutrients and living space. The intestinal environment itself changes according to what we eat and how our gastrointestinal tract functions.

This is why I am increasingly interested in the idea that feeding the microbiome may be just as important as supplementing it.

A probiotic capsule introduces selected microorganisms, but those organisms still have to live in an intestinal environment. If the diet contains very little fermentable fiber and consists primarily of highly processed foods, there may be less substrate available for beneficial microbial metabolism.

This is one reason foods such as vegetables, fruits, legumes, whole grains, nuts and seeds remain important. They provide the dietary fiber and other compounds that interact with the microbiome in ways a capsule alone cannot necessarily reproduce.

Fermented Foods Are Not the Same Thing as Probiotic Supplements

Yogurt, kefir, sauerkraut, kimchi and other fermented foods are often described as probiotic foods, but the terminology deserves some precision.

Some fermented foods contain live microorganisms that may have beneficial effects, but the organisms, concentrations and survival characteristics vary considerably. Some commercially produced foods are pasteurized after fermentation, which can eliminate living organisms while preserving the fermented product.

That does not make the food unhealthy. It simply means we should not assume that every fermented food is equivalent to a clinically studied probiotic preparation.

On the other hand, a food does not need to meet the formal definition of a probiotic to be nutritionally valuable. Plain yogurt, for example, provides protein, calcium and other nutrients regardless of whether a particular bacterial strain has been demonstrated to improve memory.

Food and supplementation are related but not interchangeable concepts.

What About Inflammation?

One of the more compelling theories connecting the microbiome with cognitive aging involves inflammation.

Chronic systemic inflammation has been associated with a variety of age-related diseases, including cardiovascular disease and neurodegenerative disorders. The gut microbiome interacts with the immune system and intestinal barrier, so researchers have investigated whether altering the microbiome might influence inflammatory signaling.

Some probiotic studies have reported changes in inflammatory markers, and recent systematic reviews have investigated potential effects on inflammatory cytokines and oxidative stress. But again, the evidence is inconsistent, and a change in a blood biomarker does not necessarily mean that a patient will live longer, think more clearly or avoid dementia.

This distinction between biological plausibility, biomarker improvement and meaningful clinical outcomes is one that physicians have to keep making.

Medicine is full of interventions that changed a laboratory value beautifully without changing the patient’s ultimate outcome.

Probiotics Are Not a Treatment for Alzheimer’s Disease

I want to make this particularly clear because the moment the words “probiotics” and “cognition” appear together, someone will inevitably interpret the finding as evidence that probiotics treat Alzheimer’s disease.

They do not.

There is intriguing research involving probiotics, cognitive impairment and neurodegenerative disease, including randomized trials and meta-analyses involving patients with mild cognitive impairment and Alzheimer’s disease. Some studies have reported improvements in cognitive testing, particularly after several months of supplementation. One recent meta-analysis of 15 randomized controlled trials involving 994 participants with mild cognitive impairment or Alzheimer’s disease reported an improvement in cognitive scores, with stronger effects in studies lasting at least 12 weeks.

But these studies are not evidence that probiotics reverse Alzheimer’s disease, remove amyloid plaques, cure dementia or replace established medical treatment.

Those are entirely different claims.

The research is promising enough to justify further investigation, but not strong enough to justify selling probiotics as a dementia treatment.

Safety Matters Too

For most healthy people, probiotics are generally well tolerated, with gastrointestinal symptoms such as gas or bloating being among the more common complaints. But “natural” does not mean “risk-free.”

Serious infections involving probiotic organisms are rare but have been reported, particularly in severely immunocompromised or critically ill patients and in people with certain underlying medical conditions. The risk is low for most healthy individuals, but it is one reason I would not casually recommend high-dose probiotic supplementation to someone who is severely ill, immunocompromised or has a central venous catheter without discussing it with the treating medical team.

There is also the practical issue of product quality. Supplements are not interchangeable, and the label does not tell the entire story. A product containing a large number of organisms is not necessarily supported by clinical evidence for the outcome you care about.

If the goal is cognition, I would want evidence that the specific strain or combination of strains has been studied for cognition rather than simply accepting a large number on the front of a bottle.

The Brain Still Has Some Old-Fashioned Requirements

There is a tendency in modern nutrition to become fascinated with whatever the newest research topic happens to be. Five years ago it was one supplement. Then another. Now the microbiome and gut-brain axis have become extraordinarily popular.

But if someone asks me what they should do today to protect their brain as they age, my answer is not going to begin with a probiotic.

I would start with the things we already know matter.

Control blood pressure. Do not smoke. Exercise regularly. Maintain a healthy metabolic profile. Get adequate sleep. Eat a diet rich in vegetables, fruits, whole grains, legumes, nuts and other minimally processed foods. Consume adequate protein. Address hearing and vision problems. Stay socially and intellectually engaged. Treat depression and other medical conditions. Avoid excessive alcohol. Take medications as prescribed.

And then, if someone wants to discuss probiotics, we can have that conversation.

That is not because probiotics are uninteresting. Quite the opposite. It is because emerging science should complement established medicine rather than replace it.

The Gut-Brain Connection Is Becoming Harder to Ignore

What I find most fascinating about this research is not the idea that everyone should start taking a probiotic tomorrow morning. It is the broader lesson that the human body does not function as a collection of independent organs.

The intestine and the brain communicate. The immune system communicates with both. Microorganisms living within us participate in metabolism. Dietary fiber becomes a substrate for bacterial metabolism. Bacterial metabolites influence host physiology. Neural pathways connect the gut to the brain. The brain influences the intestine in return.

We have spent much of modern medicine dividing the body into specialties and organs because doing so makes an extraordinarily complicated system easier to study. There is tremendous value in that approach, but occasionally science reminds us that the divisions are artificial.

The gastrointestinal tract is not simply a tube through which food passes.

It is an immunologic organ, an endocrine organ, a metabolic organ and a home for an enormous microbial ecosystem that communicates with the rest of the body.

And apparently, at least according to a growing body of research, it may have something to say to the brain.

So Should You Take a Probiotic for Your Brain?

My answer would be: maybe, but don’t expect a miracle.

The evidence is intriguing. The 2026 lifespan meta-analysis found measurable cognitive benefits in several age groups, with the strongest and broadest effects occurring among older adults. The most prominent findings involved overall cognition, processing speed, memory and spatial ability, particularly after approximately 12 weeks of supplementation.

But the studies are heterogeneous, probiotic preparations differ, and other meta-analyses have found that the certainty of the evidence remains low or that the overall effect is inconsistent.

That means I would view probiotics as an interesting adjunct, not a replacement for the fundamentals of healthy aging.

There is also something reassuring about that conclusion. We do not need to turn cognition into another complicated supplement regimen.

Take care of your cardiovascular system. Exercise. Sleep. Eat real food. Maintain meaningful social and intellectual activity. Manage your medical conditions. And if you are considering a probiotic, understand what organism you are taking and why you are taking it rather than choosing a bottle simply because the label contains an impressive number of billions.

The gut-brain connection is real. Exactly how important it is, and exactly how much we can manipulate it to improve human health, is still being worked out.

That is where good science becomes particularly interesting. We do not have to pretend that we already know the answer.

Sometimes the most worthwhile medical discoveries begin with a much simpler realization: something we thought was unrelated to the brain may have been talking to it all along.

Super Cereals: Why Oats and Rye May Be the Breakfast Champions

There is something wonderfully ordinary about breakfast cereal. It is not glamorous food, and it certainly does not have the cultural cachet of some of the more fashionable foods that appear on nutrition websites and social media. Yet cereal, particularly when we are talking about whole grains rather than brightly colored boxes filled primarily with refined flour and added sugar, can be an excellent way to start the day. Now a new systematic review has given us another reason to pay attention to what is sitting in the breakfast bowl: among the various cereal fibers researchers examined, oats and rye appeared to have the strongest effects on satiety and other measures of appetite.

The review, titled “Cereal Fibers and Satiety: A Systematic Review,” was published in Nutrition Reviews in 2026 by Alicia Machalias and colleagues. The investigators examined 48 randomized crossover studies looking at cereal fiber and measures of appetite, including hunger, fullness, satiety, desire to eat and the amount of food participants expected to consume. The results were interesting because not all cereal fibers appeared to behave the same way. Higher-fiber foods made from rye and oats produced more favorable appetite responses than lower-fiber controls, while wheat, barley and several isolated or functional fibers generally produced weaker effects.

Before we turn a bowl of oatmeal into a medical miracle, however, there is an important qualification. The study found fairly convincing improvements in how full people felt, but those sensations did not consistently translate into a measurable reduction in how much they subsequently ate. In other words, eating a high-fiber breakfast may make you feel fuller for longer, but the human appetite is sufficiently complicated that the body can sometimes compensate later. That distinction matters, because there is a tremendous difference between saying that a food improves satiety and saying that the food causes weight loss. The first conclusion is supported by this review; the second is considerably more complicated.

Why Satiety Matters

Satiety is the physiological sensation that tells us we have had enough to eat and helps suppress hunger after a meal. It is different from simply feeling that the stomach is physically full. Appetite is regulated through an elaborate interaction between the gastrointestinal tract, the brain, the autonomic nervous system, hormones and metabolic signals. The hypothalamus and other areas of the brain integrate information arriving from the digestive tract and circulating nutrients, while intestinal hormones such as GLP-1, peptide YY and cholecystokinin participate in signaling that influences hunger and fullness.

Fiber can influence several of these processes simultaneously.

First, fiber tends to increase the physical bulk of a meal. Foods containing intact plant structures generally require more chewing and take longer to consume than many highly refined foods. Fiber can also absorb water, increasing the volume of gastrointestinal contents. Certain soluble fibers become viscous when mixed with water, potentially slowing gastric emptying and altering the rate at which nutrients reach the small intestine.

The composition of the meal can therefore influence the signals sent from the digestive tract to the brain. This is one reason a bowl of minimally processed oats can behave differently from a highly refined breakfast product containing roughly the same number of calories.

The body is not merely counting calories. It is constantly receiving information about the physical characteristics of the meal, the rate at which nutrients are delivered and the metabolic consequences of digestion.

Oats Have a Particularly Interesting Fiber

Oats have earned much of their nutritional reputation because of a soluble fiber called beta-glucan.

Beta-glucan is a type of soluble fiber that can form a viscous mixture in the gastrointestinal tract. Oats are particularly rich in it, and barley is another important dietary source. The viscosity created by beta-glucan is one proposed explanation for some of the effects seen with oat consumption, although the physiology is undoubtedly more complicated than a single fiber molecule.

Several studies have found that oat preparations containing greater amounts of beta-glucan can increase subjective satiety compared with lower-beta-glucan preparations. The 2026 systematic review found a favorable and relatively consistent effect of higher-fiber oat products on appetite measures.

This is one reason I generally prefer actual oats to the highly processed, sugary breakfast products that merely happen to have the word “oat” prominently displayed on the package.

There is a substantial difference between eating a bowl of old-fashioned rolled oats with fruit and nuts and eating a heavily sweetened cereal whose marketing department has decided that putting oats somewhere on the ingredient list makes it a health food.

Rye Deserves More Attention

Rye is perhaps the underappreciated member of the breakfast-grain family.

Americans tend to think about wheat when they think about bread and oats when they think about breakfast cereal. Rye does not receive nearly as much attention, despite having an interesting nutritional profile and a substantial amount of dietary fiber. In the new review, rye-derived fiber demonstrated particularly favorable effects on fullness and satiety.

There is evidence that the physical form of rye matters as well. Less-refined rye products, such as rye kernels and certain porridges, may produce stronger satiety effects than more highly processed rye flours. Earlier randomized research comparing different rye preparations found that rye bran could produce a stronger satiety response than more refined rye fractions.

That observation illustrates a larger principle in nutrition: the food itself matters, but so does the degree to which we have processed it.

A whole grain that still retains its original structure behaves differently in the digestive tract from a grain that has been milled into a fine flour, mixed with sugar and fat, extruded into a highly processed shape and then marketed as a breakfast food.

Whole Grain Does Not Mean “Eat Unlimited Amounts”

There is another misconception worth addressing. Once a food acquires the label “whole grain,” some people seem to assume that calories no longer count.

They do.

Whole grains are nutritionally valuable, but they are still sources of energy. A large bowl of oatmeal covered in brown sugar, honey, dried fruit and a generous handful of nuts can contain considerably more calories than the person eating it realizes. The ingredients may all be perfectly respectable foods, but the total energy content still matters.

Satiety can help regulate food intake, but it is not an exemption from energy balance.

This is one reason I find the 2026 review particularly useful. The researchers found meaningful improvements in subjective appetite measures, but the evidence for reduced subsequent energy intake was much weaker.

That distinction prevents us from taking a reasonable nutritional observation and turning it into another exaggerated diet claim.

Fiber Does Much More Than Control Hunger

Even if we completely ignored the satiety question, there would still be plenty of reasons to eat more fiber.

Dietary fiber supports gastrointestinal health and influences the composition and activity of the gut microbiome. Certain fermentable fibers are metabolized by intestinal bacteria into short-chain fatty acids, including acetate, propionate and butyrate. These metabolites participate in communication between the intestinal tract and the rest of the body and have been associated with effects on intestinal barrier function, immune signaling and metabolic physiology.

Fiber also influences bowel function. Insoluble fiber adds bulk to stool and can help promote regularity, while soluble and fermentable fibers can alter stool consistency and serve as substrates for intestinal bacteria.

There is also a broader cardiovascular story. Higher consumption of whole grains and dietary fiber has been associated with better cardiometabolic health, including more favorable lipid profiles and lower risk of several chronic diseases. Not every association proves that fiber itself is the cause, because people who eat more whole grains often have other healthy behaviors as well, but the overall evidence is strong enough that dietary fiber deserves a permanent place in a healthy diet.

Not All Cereals Are Created Equal

This is where the cereal aisle can become confusing.

Walk into any supermarket and you will find dozens of boxes making impressive claims about whole grains, fiber, protein, vitamins and minerals. Some are genuinely nutritious. Others are essentially refined carbohydrates with enough added nutrients to make the nutrition label look respectable.

The word “cereal” tells us remarkably little about the nutritional quality of the food.

A breakfast made from intact or minimally processed oats is fundamentally different from a sugary cereal made primarily from refined grains. A bowl of steel-cut oats with berries and walnuts has a different metabolic and nutritional profile from a sweetened cereal eaten with flavored milk.

The ingredient list matters. The nutrition facts panel matters. The amount of added sugar matters. The amount of fiber matters. And perhaps most importantly, the portion matters.

If you are buying a packaged cereal, I generally want to see whole grains high on the ingredient list, a meaningful amount of dietary fiber and relatively little added sugar. The exact numbers will vary by product, but a cereal containing only a gram or two of fiber per serving should not be mistaken for a particularly high-fiber breakfast simply because the front of the box contains pictures of wheat stalks.

What Happens to Blood Sugar?

The type and processing of the carbohydrate also influence what happens after breakfast.

Refined grains can be digested relatively quickly, particularly when they have been milled into fine flour and processed into foods that are easy to chew and swallow. Whole grains retain more of their original structure, and their fiber can slow digestion and alter the rate at which glucose enters the bloodstream.

Oats are especially interesting because beta-glucan can increase the viscosity of the intestinal contents and influence carbohydrate digestion and absorption. This can help moderate post-meal glucose responses.

But once again, we should avoid oversimplification. A person with diabetes does not have a free pass to consume unlimited oatmeal simply because oatmeal contains soluble fiber. Portion size, total carbohydrate, added sugar, accompanying protein and fat, medications, insulin sensitivity and individual physiology all matter.

A bowl of plain oats topped with berries and Greek yogurt is a different metabolic event from a bowl of oats containing several tablespoons of brown sugar and a large quantity of dried fruit.

The Breakfast Bowl Can Be a Complete Meal

One of the advantages of oats is how easily they can be combined with other nutritious foods.

A basic bowl of oats provides carbohydrate and fiber, but adding protein and healthy fats can make the meal considerably more substantial. Greek yogurt, milk, nuts, seeds, peanut butter or eggs on the side can provide protein. Berries and other fruit provide additional fiber and micronutrients. Cinnamon can add flavor without requiring large quantities of added sugar.

There is no nutritional requirement that breakfast cereal be eaten directly from a box.

In fact, one of my favorite approaches to breakfast is to think of the meal as a collection of complementary foods rather than as a single packaged product. The oats provide whole-grain carbohydrate and fiber. The dairy or eggs provide protein. Fruit adds additional fiber and micronutrients. Nuts or seeds contribute unsaturated fats and minerals. The result is a much more nutritionally complete breakfast than a bowl of highly sweetened cereal eaten by itself.

What About Protein?

This is one area in which traditional cereal breakfasts sometimes fall short.

Fiber receives most of the attention when we discuss oats and rye, but protein contributes substantially to satiety as well. A breakfast consisting almost entirely of rapidly digested carbohydrate may leave some people hungry relatively quickly, while combining carbohydrate with an adequate protein source can produce a more satisfying meal.

That does not mean every breakfast needs to become a high-protein fitness meal containing a scoop of powdered protein. Eggs, Greek yogurt, cottage cheese, milk, nuts, seeds and other ordinary foods can provide protein quite effectively.

Again, the goal is not to find one magical ingredient. It is to construct a meal that makes physiological sense.

The Importance of the Grain’s Structure

One of the more interesting concepts emerging from nutrition research is that the physical structure of food can matter almost as much as its nutrient composition.

Consider a whole oat groat. The grain retains much of its original architecture. Steel-cut oats are chopped pieces of the groat. Rolled oats have been steamed and flattened. Instant oats are generally more processed and often cooked more rapidly. None of these foods is inherently unhealthy, but their physical structure and processing can influence digestion, texture, gastric emptying and the rate at which carbohydrate becomes available.

The same principle applies to wheat and rye.

This does not mean that steel-cut oats are medically superior to rolled oats in every circumstance, nor does it mean that instant oatmeal is somehow toxic. The differences are often matters of degree rather than dramatic distinctions between healthy and unhealthy foods. But when we talk about satiety, digestion and metabolic responses, food structure deserves more attention than it usually receives.

A Word About Weight Loss

Whenever research mentions appetite control, the conversation quickly turns toward weight loss.

That is understandable, but I would caution against making too much of it.

If a person eats a breakfast that keeps him or her satisfied for several hours and therefore reduces snacking, that can certainly be useful for weight management. Over months and years, small differences in food intake can matter. But no individual cereal is going to overcome an overall dietary pattern that consistently provides more calories than the body requires.

Weight regulation involves genetics, hormones, sleep, physical activity, medications, psychological factors, food availability, eating behavior and countless environmental influences. Appetite is only one piece of the equation.

The 48-study review is therefore best understood as evidence about one physiological mechanism rather than a prescription for a weight-loss diet. Oats and rye appear particularly good at producing feelings of fullness, but that does not make them magic weight-loss foods.

My Breakfast Recommendation

If somebody asked me to build a simple breakfast around this research, I would not make it complicated.

Start with a minimally processed whole grain, and oats would be an excellent choice. If you enjoy rye, whole-grain rye bread or a minimally processed rye cereal is another reasonable option. Add a source of protein, such as eggs, Greek yogurt or milk. Add fruit if you like it. Nuts or seeds can provide healthy fats and additional nutrients. Keep added sugar modest.

And then eat it.

That last part sounds obvious, but nutrition has become unnecessarily complicated. People are constantly looking for powders, extracts, exotic berries and expensive supplements when ordinary foods have been doing this work for thousands of years.

Oats are not exotic. Rye is not exotic. Neither requires a subscription service, a proprietary blend or an influencer’s discount code.

The Super Cereal Is Not Necessarily the Most Exciting One

There is something reassuring about the conclusion of this research.

The cereal that may be particularly useful for appetite control is not necessarily the cereal with the most elaborate packaging, the longest list of added vitamins or the most aggressive health claims. It may be one of the simplest foods in the grocery store: oats.

Rye, another relatively humble grain, also performed impressively in the review. Both provide substantial amounts of fiber, and both can be incorporated into ordinary meals without turning breakfast into a nutritional science experiment.

The larger lesson is that we should pay more attention to the basic structure of our food. Whole grains provide fiber, vitamins, minerals and other bioactive compounds. Fiber can slow digestion, influence gastrointestinal signaling and contribute to satiety. Certain fibers, particularly those found in oats and rye, appear to be especially effective at improving subjective measures of fullness.

But the evidence also reminds us to keep our enthusiasm in check. Feeling full is not the same thing as automatically eating less, and eating less at one meal is not the same thing as losing weight over the long term.

Still, if you are looking for a breakfast that is nutritious, inexpensive, easy to prepare and likely to keep you satisfied for a while, there is little reason to reinvent the wheel.

A bowl of oats, perhaps some fruit, a reasonable source of protein and a little common sense is a pretty good place to start.

And if you want to branch out from oats, give rye a chance. It appears to have earned its place at the breakfast table.

Can Children Thrive Without Meat? What the Research Actually Says About Plant-Based Diets

I will begin with a confession that probably does not surprise anyone who has read my writing for very long: I am not a vegetarian, and I am not a vegan. I do not subscribe to either philosophy, and I have no intention of giving up meat. I like meat, I have always eaten meat, and from both a personal and nutritional standpoint, I am perfectly comfortable including animal products in my diet. That said, being a physician means I do not get to dismiss an interesting piece of research simply because its conclusions do not necessarily correspond with my own dietary preferences. Medicine would become a rather dangerous profession if we only examined evidence that confirmed what we already believed.

That is why I found a recent analysis of plant-based diets in children interesting. The question was not whether I should become a vegetarian, nor was it an argument that every child ought to stop eating meat. Instead, the researchers looked at what actually happens nutritionally and metabolically when children and adolescents follow vegetarian or vegan diets. Their findings were considerably more nuanced than the way nutrition debates are usually presented in public. The basic conclusion was that children can grow and develop on carefully planned vegetarian and vegan diets, but those diets can also create nutritional vulnerabilities that require deliberate attention, particularly when animal products are completely eliminated.

The paper is titled “Lacto-ovo-vegetarian and vegan diets in children and adolescents: a systematic review and meta-analysis of nutritional and health outcomes.” It was published in 2026 in Critical Reviews in Food Science and Nutrition by Sofia Lotti and colleagues. The researchers searched the medical literature through March 2025 and ultimately included 59 studies involving 48,626 children and adolescents under the age of 18. Of those participants, 7,280 followed lacto-ovo-vegetarian diets, 1,289 were vegan, and 40,059 were omnivores. That is a substantial body of information, although it is important to remember that a meta-analysis is only as strong as the individual studies that go into it.

What caught my attention was that the results did not produce a simple nutritional victory for one dietary pattern. Instead, they illustrated something I tell patients all the time: every dietary pattern has strengths and weaknesses, and the more restrictive the diet becomes, the more carefully it needs to be constructed.

The Benefits Are Real

There were some favorable findings among children consuming vegetarian and vegan diets. Plant-based diets tended to provide more fiber and higher intakes of several nutrients, including folate, vitamin C and magnesium. Children following these diets also tended to have lower total and LDL cholesterol levels than omnivorous children. Those findings are not particularly surprising when you consider what these diets commonly contain: fruits, vegetables, legumes, whole grains, nuts and seeds.

Fiber deserves particular attention because it is something many children do not consume enough of. Fiber supports normal gastrointestinal function, contributes to satiety, influences the gut microbiome and can help moderate the rise in blood glucose following a meal. Diets rich in fruits, vegetables, legumes and whole grains can therefore have meaningful advantages, particularly when they replace highly processed foods rather than simply replacing a hamburger with an equally processed plant-based substitute.

The cardiovascular findings are also interesting. The vegetarian and vegan children in the analysis generally had lower cholesterol concentrations, including lower LDL cholesterol. That does not mean that a child needs to become vegan to have a healthy cardiovascular system, nor does it prove that eating meat causes cardiovascular disease in children. Childhood cardiovascular risk is a complicated subject, and lipid concentrations are only one piece of the picture. What the findings do suggest is that diets emphasizing plant foods can produce favorable metabolic characteristics.

That is worth acknowledging even if you are somebody like me who has no intention of giving up a steak.

But Children Are Not Small Adults

This is where the discussion becomes much more interesting.

Adults can make dietary decisions based on long-term preferences, ethical beliefs, environmental concerns, religious practices or personal health goals. Children are different. A growing child has a relatively high requirement for energy and nutrients because the body is simultaneously building bone, muscle, blood, connective tissue and brain tissue. The nutritional margin for error is therefore smaller.

A diet that looks perfectly reasonable on paper for a 45-year-old adult may require considerably more thought when applied to a growing six-year-old.

This is particularly true because children have relatively small stomachs. They cannot necessarily compensate for a low-energy-density diet by simply eating enormous quantities of food. A child who fills up on bulky, high-fiber foods may feel full before consuming enough calories, protein or certain micronutrients to support optimal growth.

That does not make vegetables, legumes or whole grains unhealthy. Quite the opposite. It simply means that pediatric nutrition requires consideration of energy density, protein, fat and micronutrients in addition to the usual advice to “eat more vegetables.”

Vitamin B12 Is the Nutrient I Would Watch Most Closely

Vitamin B12 is probably the most obvious example of the nutritional challenge created by eliminating animal products.

B12 is required for normal DNA synthesis, red blood cell production and neurologic function. The natural food supply of B12 is overwhelmingly concentrated in animal-derived foods such as meat, fish, eggs and dairy products. There are fortified foods and supplements, but a vegan diet does not automatically provide reliable B12.

The recent meta-analysis found lower B12 intake among plant-based groups, and vitamin B12 deficiency was more evident among vegan children. Importantly, however, the problem is largely preventable when fortified foods or appropriate supplementation are used.

That point deserves emphasis because it changes the interpretation of the research. The problem is not that a vegan child is doomed to become B12 deficient. The problem is that a vegan diet without a reliable B12 source is nutritionally incomplete.

A 2023 systematic review and meta-analysis specifically examining B12 levels in children and adolescents found that children consuming plant-based diets had lower B12 levels than omnivorous children overall, with the difference particularly apparent among vegan and macrobiotic diets. The researchers also found that adequate B12 intake from food or supplements could eliminate that difference.

From a medical perspective, that is a fairly straightforward lesson: if a child does not eat foods that naturally provide B12, somebody needs to make certain that B12 is coming from somewhere else.

Calcium Is Another Concern

Calcium becomes particularly important during childhood and adolescence because the skeleton is being built for the future.

Bone is not static tissue. Throughout childhood, the skeleton is undergoing continuous remodeling, with periods of bone formation substantially exceeding bone resorption as children grow. Adolescence is especially important because a large proportion of adult bone mass is accumulated during these years.

Dairy products provide a convenient and highly bioavailable source of calcium, although they are certainly not the only source. Fortified plant milks can provide substantial calcium, and foods such as calcium-set tofu, certain leafy greens and fortified products can contribute as well.

The challenge is consistency.

The recent meta-analysis found that vegan children in particular had lower calcium intakes. Other systematic reviews have also raised concerns about bone mineral content among vegetarian and especially vegan children, although the long-term clinical significance of some of these differences remains uncertain.

This is precisely why I would not tell parents simply to “give the child vegetables.” I would want to know what the child actually eats. Does the child consume a fortified calcium-containing beverage? Is calcium-set tofu part of the diet? Are there other reliable sources? How much protein is being consumed? Is vitamin D adequate?

Nutrition is about the entire pattern, not a single food group.

Iodine Is Easy to Forget

Iodine is another nutrient that does not receive much attention until somebody becomes deficient.

The thyroid gland requires iodine to synthesize thyroid hormones. These hormones are fundamental to normal metabolism and, particularly during childhood, normal growth and neurologic development.

Some vegetarian and vegan children have lower iodine intake, and several studies have found differences in iodine status between plant-based and omnivorous groups. The degree of risk depends heavily on the foods consumed, use of iodized salt, fortified foods and supplementation.

This is a good example of why dietary labels can sometimes be misleading. Saying that a child is “vegan” tells me something about what the child does not eat, but it tells me very little about what the child actually does eat.

A vegan child consuming a carefully planned diet with appropriate fortified foods may have excellent nutritional intake. Another child eating a highly restrictive diet consisting largely of fruits, vegetables and a handful of preferred foods could have significant nutritional deficiencies despite technically following the same dietary philosophy.

Zinc, Iron and Vitamin D Deserve Attention Too

Zinc is involved in immune function, DNA synthesis, growth and wound healing. It is found in meat and seafood, but also in beans, nuts, seeds and whole grains. The complication with plant sources is that they often contain phytates, compounds that can reduce the absorption of minerals such as zinc and iron.

Iron is another nutrient that requires some nutritional sophistication. Plant foods contain non-heme iron, while meat provides highly bioavailable heme iron. Vitamin C can substantially improve absorption of non-heme iron, which is one reason combining legumes or iron-rich plant foods with fruits and vegetables containing vitamin C can be helpful.

The recent review found lower ferritin and, among some groups, greater evidence of iron deficiency or anemia, particularly in vegan children. At the same time, many children consuming plant-based diets did not have clinically significant iron deficiency. Again, the answer is not that plants are incapable of providing iron. They can. The issue is that the quantity, bioavailability and overall dietary pattern matter.

Vitamin D is another nutrient that deserves attention regardless of whether a child eats meat. Dietary intake can be inadequate across dietary patterns, and vitamin D status is influenced by factors extending well beyond food, including sun exposure, season, latitude, skin pigmentation and supplementation. In other words, vitamin D is not exclusively a plant-based-diet issue.

Protein Is More Complicated Than the Internet Makes It Sound

Whenever somebody discusses vegan diets, protein inevitably enters the conversation, usually accompanied by a dramatic claim from one side or the other.

The truth is considerably less dramatic.

Children can obtain protein from legumes, soy, tofu, tempeh, nuts, seeds, grains and other plant foods. A well-planned vegetarian or vegan diet can provide adequate protein. But adequate protein is not simply a matter of identifying one plant food that contains protein. The child’s total daily intake, energy intake, food variety and growth trajectory all matter.

There is also an important practical distinction between obtaining adequate protein and obtaining an adequate amount of every essential amino acid in an easily consumed diet. Most plant foods contain protein but vary in their amino acid profiles and digestibility. Eating a varied diet largely solves this problem because different foods complement one another nutritionally.

For a growing child, however, I care about whether the child is actually eating enough food to meet those needs. A theoretically adequate diet that a picky four-year-old refuses to eat is not an adequate diet in practice.

That is where the real-world challenge of pediatric nutrition appears.

Growth Is the Ultimate Test

When I evaluate nutrition in a child, I am not particularly interested in whether the parents can convince me that their dietary philosophy is perfect. I want to know whether the child is growing appropriately.

Height, weight, body mass index, growth velocity and pubertal development provide important clinical information. A child’s growth curve is considerably more useful than an argument on social media about whether one dietary pattern is morally or biologically superior.

The 2026 meta-analysis found that vegetarian and vegan children tended to have a leaner body composition. Some groups had lower weight and BMI measures, and vegan children were, on average, somewhat shorter in the analyzed studies. These findings do not establish that a vegan diet causes poor growth in every child, but they do reinforce why growth monitoring matters.

Another systematic review published in 2024 reached a similar general conclusion: well-planned plant-based diets can work in children, but vegan diets may carry greater risks for inadequate growth and nutritional deficiencies, particularly when supplementation and careful planning are absent.

That distinction is important. Can a child thrive on a vegan diet? Yes. Does that mean every vegan diet provided to a child will be nutritionally adequate? Absolutely not.

And This Is Where I Part Company With Some of the More Extreme Arguments

I have no problem acknowledging that a carefully constructed vegetarian or vegan diet can support normal childhood growth. The evidence does not justify claiming otherwise.

But I also think we have to be honest about what “carefully constructed” means.

It means somebody is paying attention to B12. It means calcium is being deliberately supplied. It means iodine is considered. It means vitamin D, iron, zinc and protein are not afterthoughts. It means the child’s caloric intake is sufficient. It means growth is being monitored. It means supplementation is used when necessary. And for infants and very young children, it means the parents should be receiving appropriate pediatric nutritional guidance rather than improvising from information found on the internet.

That is considerably different from simply removing meat, eggs and dairy and assuming that vegetables will take care of everything.

The distinction is especially important because children have no say in many of these dietary decisions. An adult can choose a restrictive diet and accept the consequences of poor planning. A child is dependent upon the adults around them to provide the nutrients required for growth and development.

There Is a Difference Between Plant-Based and Vegan

I also think the terminology matters.

A diet containing large quantities of vegetables, fruits, whole grains, beans, nuts and seeds while also including fish, eggs, dairy products or meat is very different nutritionally from a strict vegan diet. Even a lacto-ovo-vegetarian diet, which includes eggs and dairy, is nutritionally different from veganism because eggs and dairy provide B12, protein, calcium and other nutrients.

This is why I am suspicious whenever someone describes a diet as simply “plant-based” without explaining what that actually means.

If somebody tells me they eat mostly plants but also enjoy salmon, eggs, yogurt and an occasional steak, I have a very different nutritional conversation than I would with somebody who eats absolutely no animal products.

The label is less important than the contents of the plate.

My Own Diet Has Not Changed

For the record, none of this has convinced me to become vegetarian.

I still eat meat, and I am going to continue eating meat. This article is not an attempt to persuade anyone, including myself, to abandon animal products. Rather, it is an attempt to look at an interesting piece of pediatric nutrition research without turning it into a political or philosophical argument.

Medicine should be able to do that.

I can acknowledge that children following carefully planned vegetarian and vegan diets can obtain plenty of fiber, folate, vitamin C, magnesium and other nutrients. I can acknowledge that they may have favorable cholesterol profiles. I can also acknowledge that eliminating animal products creates nutritional challenges that do not simply disappear because the diet contains plenty of vegetables.

Both statements can be true at the same time.

What I Would Tell a Parent

If a family chooses a vegetarian diet for a child, I would not automatically consider that child nutritionally compromised. I would want to know what the child eats, how much the child eats and how the child is growing. If the family chooses a vegan diet, I would be even more interested in the details, particularly B12, calcium, vitamin D, iodine, iron, zinc, protein and overall caloric intake.

I would also encourage parents to involve the child’s pediatrician and, when appropriate, a registered dietitian with experience in pediatric plant-based nutrition. This is particularly important during infancy, early childhood and adolescence, when nutritional demands are changing rapidly.

And I would strongly prefer a thoughtfully planned diet over a poorly planned diet regardless of whether it contains meat.

That last point is important because omnivorous diets are not automatically healthy. A child can eat meat every day and still have a terrible diet if the rest of the food consists largely of ultra-processed foods, sugary drinks, refined carbohydrates and very little fruit, vegetables or fiber. Meat does not magically transform an otherwise poor diet into a good one.

Likewise, a plant-based diet does not automatically become healthy simply because everything on the plate originated in a plant.

The Larger Lesson

What I find most useful about this research is that it moves the conversation away from dietary tribalism and toward something much more practical: nutritional adequacy.

Children need calories. They need protein. They need essential fatty acids. They need iron, zinc, iodine, calcium, vitamin D, B12, folate and a long list of other micronutrients. Their brains need to develop, their bones need to mineralize, their blood needs to be produced and their muscles need to grow. The body is not particularly interested in whether those nutrients arrived because of a particular dietary philosophy. It simply needs them.

A well-planned vegetarian diet can meet those requirements. A well-planned vegan diet can meet them as well, provided that the diet is appropriately supplemented and monitored. But the more foods that are excluded, the more deliberate the nutritional planning needs to become.

That is not an indictment of vegetarianism or veganism. It is simply physiology.

And perhaps that is the most reasonable way to read this study. It does not tell me that children need to be vegan. It does not tell me that children need to eat meat. What it tells me is that growing children have nutritional requirements that cannot be negotiated away by dietary preference. If parents choose to eliminate major food groups, they assume an additional responsibility to understand what those foods were providing and to replace those nutrients appropriately.

As a physician, that is ultimately what interests me. I am much less concerned with whether someone wins an argument about meat than I am with whether a child is growing normally, developing normally and receiving everything the human body requires to do its extraordinarily complicated job.

For my own part, I will continue to eat meat.

But I will also continue to read the research.

Vitamin B12: The Quiet Vitamin Your Nerves and Blood Cannot Do Without

Vitamin B12 is one of those nutrients that rarely receives the attention given to vitamin C, vitamin D, calcium or iron, yet its importance to the human body is difficult to overstate. It is required for normal red blood cell production, DNA synthesis and neurologic function, and when a deficiency develops, the consequences can extend well beyond simple fatigue. In the clinic, I am often reminded that nutrition is not merely about preventing obvious diseases such as scurvy or rickets. Sometimes the most important nutrients are the ones quietly supporting cellular processes every minute of every day, without announcing their presence until something goes wrong.

Vitamin B12, also called cobalamin, is particularly interesting because the body is remarkably good at storing it. The liver can hold several years’ worth of B12, which means that a person can gradually become deficient without noticing an immediate change in how he or she feels. This long storage capacity is one reason a deficiency may be overlooked for months or even years. By the time symptoms become apparent, the problem may no longer be a simple dietary deficiency. It may instead reflect an underlying problem with absorption, gastric physiology, medication use or gastrointestinal disease.

For most healthy people under the age of 50 who consume a varied diet containing animal products, obtaining adequate B12 is not particularly difficult. Vitamin B12 is naturally present in meat, poultry, fish, shellfish, eggs and dairy products. Plant foods do not naturally contain meaningful amounts of active vitamin B12, which is why people following a strict vegan diet need to obtain the vitamin through fortified foods or a reliable supplement. Some vegetarians who consume eggs and dairy can obtain sufficient B12 through their diets, although intake varies considerably depending on how restrictive the diet is.

The biology of B12 helps explain why the vitamin matters so much. One of its most important jobs is supporting DNA synthesis and cell division. That becomes particularly important in tissues in which cells are continually being replaced, including the bone marrow, where red blood cells are produced. B12 works closely with folate in this process. When B12 is deficient, DNA synthesis becomes impaired and developing red blood cells cannot mature normally. The result can be megaloblastic anemia, in which the bone marrow produces unusually large, immature red blood cells.

This is where the familiar symptom of fatigue enters the story, although fatigue should never automatically be attributed to B12 deficiency. Anemia reduces the blood’s oxygen-carrying capacity, and a person may develop weakness, exercise intolerance, shortness of breath with exertion, palpitations, dizziness or a general sense of being unwell. The difficulty is that these symptoms are extraordinarily nonspecific. Iron deficiency, chronic disease, thyroid disorders, sleep disorders, depression, medication effects and countless other conditions can produce similar complaints. A patient who is tired does not necessarily need B12; the physician’s job is to determine why the patient is tired.

There is another aspect of B12 deficiency that concerns me considerably more than anemia: the nervous system.

Vitamin B12 is essential for normal neurologic function and participates in metabolic pathways necessary for maintaining myelin, the insulating material surrounding many nerve fibers. When deficiency becomes significant or prolonged, neurologic manifestations can develop independently of anemia. Patients may describe numbness or tingling in their hands and feet, difficulty with balance, a feeling that their legs are not quite responding normally, or an unusual sensation when walking. More advanced deficiency can produce weakness, impaired vibration or position sense, gait disturbances and cognitive or psychiatric changes.

The important clinical lesson is that neurologic injury from B12 deficiency should not be dismissed simply because the hemoglobin is normal. A patient can have neurologic manifestations of B12 deficiency without dramatic anemia. This is one reason a thoughtful evaluation sometimes requires looking beyond the basic complete blood count. Depending on the circumstances, clinicians may evaluate serum B12 along with methylmalonic acid and homocysteine, particularly when the B12 concentration is borderline or the clinical suspicion remains high. Methylmalonic acid is particularly useful because it rises when intracellular B12 availability is inadequate.

B12 also participates in the metabolism of homocysteine, an amino acid produced during normal cellular metabolism. Together with folate and vitamin B6, B12 helps maintain normal homocysteine metabolism. This biochemical relationship has contributed to considerable interest in B12 and cardiovascular disease. Although B12 deficiency can produce elevated homocysteine, supplementation with B12 and other B vitamins has not consistently demonstrated that simply lowering homocysteine prevents heart attacks or strokes in the general population. This distinction is important because a biochemical effect does not automatically translate into a clinical benefit.

The same caution applies to several other claims that have surrounded B12 over the years. B12 is sometimes marketed as an energy vitamin, a mood enhancer or a general-purpose treatment for fatigue. There is a kernel of truth behind some of this language because B12 is essential to normal neurologic and hematologic function, and correcting a true deficiency can dramatically improve symptoms. But giving additional B12 to someone who already has adequate levels does not turn the vitamin into a stimulant. If someone with a normal B12 level is exhausted, the appropriate response is not necessarily another bottle of supplements. It is to find the reason for the exhaustion.

B12 is also involved in the production of S-adenosylmethionine, or SAMe, a molecule involved in numerous methylation reactions throughout the body. These biochemical pathways are important for normal cellular metabolism and neurotransmitter chemistry, but it would be an oversimplification to describe B12 itself as a direct mood-boosting compound. Nutritional deficiencies can certainly affect neurologic and psychological health, but nutritional biochemistry is more complicated than the advertising language surrounding many supplements would have us believe.

Where B12 Comes From

For the average omnivore, the food supply provides a variety of opportunities to obtain B12. Fish and shellfish are particularly rich sources, while meat, poultry, eggs and dairy products provide additional amounts. Fortified breakfast cereals, nutritional yeast products and certain plant-based foods can provide B12 as well, which has become increasingly important as more people adopt vegetarian and vegan diets.

This is one area in which dietary philosophy and physiology intersect. A vegan diet can be nutritionally adequate, but B12 is the nutrient that should not be left to chance. Unlike many nutrients that can be obtained from a broad variety of plant foods, reliable natural plant sources of active B12 are essentially absent. People eating a completely plant-based diet therefore need a dependable source of fortified B12 or supplementation.

That does not mean everyone who avoids meat needs to take a handful of vitamins every morning. It means the diet needs to be planned intelligently. A person who consumes eggs and dairy may have substantially different B12 intake from someone consuming no animal products whatsoever. The more restrictive the diet, the more important it becomes to understand where the nutrient is coming from rather than assuming that a generally healthy diet automatically supplies every micronutrient.

Age Changes the Equation

One of the most important reasons B12 deficiency becomes more common with advancing age has little to do with whether an older adult eats meat. It has to do with absorption.

B12 in food is bound to proteins. In the stomach, gastric acid and digestive enzymes help release the vitamin from those proteins. B12 then binds to intrinsic factor, a protein produced by specialized cells in the stomach, allowing it to be absorbed in the terminal portion of the small intestine, the ileum. This is a remarkably specific process, and several things can interfere with it.

As people age, changes in gastric physiology can reduce the ability to release B12 from food. Atrophic gastritis and other conditions affecting the stomach can contribute to impaired absorption. Certain medications can also interfere with B12 availability, particularly when used for prolonged periods. Metformin, for example, is associated with reduced B12 absorption in some patients, while long-term use of acid-suppressing medications can also contribute to deficiency in susceptible individuals.

This is why an older patient who eats a perfectly reasonable diet can still develop B12 deficiency. The problem may not be what is on the plate. The problem may be what happens to the vitamin after the meal is swallowed.

Pernicious Anemia Is an Absorption Problem

Pernicious anemia is a classic example of why B12 deficiency is sometimes more complicated than simply eating more meat.

In pernicious anemia, an autoimmune process damages the gastric cells responsible for producing intrinsic factor. Without sufficient intrinsic factor, dietary B12 cannot be absorbed normally. A person can eat a diet containing abundant B12 and still become profoundly deficient.

Historically, pernicious anemia was a devastating disease. Before the cause and treatment were understood, patients could develop severe anemia and progressive neurologic deterioration. The discovery of the relationship between B12, intrinsic factor and absorption transformed the disease from a frequently fatal condition into one that can generally be managed very effectively with appropriate replacement therapy.

The distinction between dietary deficiency and malabsorption is clinically important because treatment may differ. Someone who simply consumes too little B12 may do very well with oral supplementation. Someone with severe malabsorption, pernicious anemia or certain gastrointestinal disorders may require a different replacement strategy, depending on the severity of the deficiency and the clinical circumstances.

Gastrointestinal Disease and Weight-Loss Surgery

The digestive tract plays such a central role in B12 absorption that diseases affecting it can create nutritional deficiencies even when a person’s diet is excellent. Crohn’s disease involving the terminal ileum is one example because that portion of the intestine is the principal site of B12 absorption. Surgical removal of the ileum can produce the same problem.

Pancreatic disease can also interfere with the complex process by which B12 is released and prepared for absorption. Previous gastrointestinal operations can matter as well. Bariatric surgery deserves particular attention because procedures that alter the stomach or small intestine can reduce the body’s ability to absorb several vitamins and minerals, including B12.

Patients who have undergone weight-loss surgery therefore require long-term nutritional follow-up. This is not simply a matter of taking supplements for several months after the operation and then forgetting about them. Bariatric surgery changes gastrointestinal anatomy and physiology, and lifelong attention to micronutrient status is part of appropriate postoperative care.

B12 and the Blood Test

When B12 deficiency is suspected, laboratory testing can help clarify the diagnosis, but no single number should be interpreted in isolation. A serum B12 level can be useful, but there are situations in which the result is borderline and does not adequately answer the clinical question.

This is where methylmalonic acid can be particularly helpful. B12 is required for the metabolism of methylmalonic acid, so deficiency causes the level to rise. Homocysteine can also increase with B12 deficiency, although it is less specific because folate deficiency and other conditions can influence it. The complete blood count may reveal macrocytosis, meaning enlarged red blood cells, but again, the absence of macrocytosis does not exclude neurologically important B12 deficiency.

The patient’s history remains just as important as the laboratory values. A strict vegan diet, previous bariatric surgery, Crohn’s disease, pernicious anemia, chronic use of certain medications, unexplained macrocytosis, neuropathy or unexplained neurologic symptoms may all change the clinician’s threshold for testing.

How Much Do We Need?

Adults generally require only a small daily amount of vitamin B12, roughly 2.4 micrograms per day. Pregnant and breastfeeding women require somewhat more. Those quantities may sound almost insignificant, particularly when compared with nutrients such as vitamin C, but the body’s requirements for micronutrients are not determined by how large the number looks on the label.

Interestingly, B12 supplements often contain hundreds or even thousands of micrograms. At first glance, that can seem excessive compared with the recommended daily intake. The explanation is absorption. Only a fraction of a large oral dose may be absorbed, and some B12 can be absorbed through a passive mechanism that does not depend entirely on intrinsic factor. This is one reason oral supplementation can sometimes be effective even in people with impaired normal absorption.

Vitamin B12 is also unusual in that no tolerable upper intake level has been established. Toxicity from B12 is considered very uncommon, even at doses far above the daily requirement. That does not mean that everyone should take enormous quantities simply because more appears to be harmless. A supplement can be unnecessary, expensive and distracting from the real cause of a medical problem, and any new supplement should be discussed with a healthcare professional when there are underlying medical conditions or prescription medications involved.

What About Macular Degeneration?

B12 has also attracted attention in ophthalmology, particularly in relation to age-related macular degeneration. B12 participates in homocysteine metabolism, and because elevated homocysteine has been associated with vascular and retinal disease, researchers have investigated whether B vitamins might influence the development or progression of macular degeneration.

This is an area where it is particularly important to distinguish between association and treatment. B12 is unquestionably important to normal neurologic and hematologic health, but that does not make it a proven treatment for every disease in which B12 metabolism has been studied. People with age-related macular degeneration should follow evidence-based ophthalmologic treatment and monitoring rather than relying on B12 supplementation as a substitute.

The Problem With Calling Everything “Vitamin Deficiency”

One of the recurring problems I see in medicine is the tendency to explain complicated symptoms with a single laboratory value. Someone feels tired, has difficulty concentrating or notices tingling in the feet, and suddenly the entire problem is attributed to a vitamin deficiency. Sometimes that diagnosis is correct. Sometimes it is not.

Medicine is rarely that simple.

B12 deficiency is important precisely because it can cause real and sometimes irreversible problems, but the answer is not to assume that every vague symptom represents a nutritional deficiency. Fatigue can be caused by anemia, thyroid disease, sleep apnea, depression, infection, medication effects, chronic inflammation and dozens of other conditions. Numbness can arise from diabetes, nerve compression, spinal disease, alcohol exposure, chemotherapy and peripheral neuropathies of many different causes. Cognitive symptoms have an equally long differential diagnosis.

The physician’s task is therefore not simply to identify a vitamin and prescribe a pill. It is to determine whether the patient is actually deficient, why the deficiency developed and whether there is an underlying disorder that needs to be addressed.

The Take-Home Message

Vitamin B12 is a small molecule with an extraordinarily large job description. It helps maintain normal red blood cell production, participates in DNA synthesis, supports neurologic function and contributes to several important metabolic pathways. The body stores substantial quantities in the liver, which provides a remarkable reserve but can also allow deficiency to develop quietly for a long time before symptoms become obvious.

For most healthy people eating a varied diet that includes meat, fish, eggs or dairy products, B12 deficiency is not inevitable. For vegans, some vegetarians, older adults, people with gastrointestinal disease, individuals taking certain medications for prolonged periods and those who have undergone bariatric or intestinal surgery, however, B12 deserves considerably more attention.

The most important lesson is that B12 deficiency is not merely a nutrition problem. It can be a dietary problem, an absorption problem, an autoimmune problem, a gastrointestinal problem or occasionally a medication-associated problem. Treating the deficiency is important, but identifying the reason for it is just as important.

From a physician’s perspective, I think that is the larger lesson with vitamins in general. We should respect them without worshipping them. The human body requires vitamins in remarkably small quantities, yet those small quantities can determine whether cells divide normally, whether red blood cells mature properly and whether nerves function as they should. A balanced diet remains the foundation, supplementation has a legitimate role when dietary intake or absorption is inadequate, and laboratory testing has value when there is a clinical reason to look.

Vitamin B12 may be quiet, but it is hardly insignificant. When the body has enough, we rarely think about it. When it does not, the nervous system, the blood and ultimately the patient’s quality of life can remind us just how much work this unassuming vitamin was doing all along.

Lentils: A Nutrition Powerhouse I Absolutely Refuse to Eat

I am going to begin this article with an admission that probably disqualifies me from ever receiving a culinary award for objectivity: I despise lentils.

There, I said it.

I have spent my professional life encouraging patients to eat nutritious foods, diversify their diets, consume more fiber, choose plant-based sources of protein, pay attention to cardiovascular health and make sensible choices at the grocery store. I can discuss the physiology of carbohydrates, the biochemistry of fatty acids and the nutritional requirements of pregnancy without blinking. I can explain why dietary fiber matters, why legumes are metabolically useful and why replacing highly processed foods with minimally processed plant foods can improve the overall quality of a diet.

And yet, when it comes to lentils, I want absolutely nothing to do with them.

My feelings about lentils have their origins in childhood. My mother used to serve them, and apparently she believed in the old-fashioned parenting philosophy that dinner was not over simply because the child had decided he was finished. We were not allowed to leave the table until the lentils were gone. It was one of those childhood battles that seemed insignificant at the time but somehow manages to leave an imprint on the nervous system decades later.

Today, I can hear the word lentils and immediately remember that experience. Smell them and I get that faintly queasy feeling. See them sitting in a bowl and my appetite begins making other plans. There are foods I dislike because I don’t particularly enjoy the flavor. Lentils are different. Lentils have history.

I will not eat them.

I am also not going to pretend that my personal culinary prejudice constitutes a medical argument.

Because, much to my annoyance, lentils are actually excellent food.

And in the interest of fairness, particularly because my wife loves them, I am going to give lentils the medical defense they deserve.

The Case for the Lentil

Lentils belong to the legume family and are classified as pulses, a term used for the edible dried seeds of leguminous plants. They have been cultivated for thousands of years and appear in traditional cuisines across the Middle East, South Asia, Europe, Africa and the Americas.

They are inexpensive, shelf-stable, easy to prepare and nutritionally dense.

In other words, they are almost offensively practical.

A half-cup serving of cooked lentils provides roughly 12 grams of protein, along with a substantial amount of dietary fiber. They also provide folate, iron, magnesium, potassium and other micronutrients.

From a nutritional standpoint, that is a pretty impressive return on investment.

From my personal standpoint, however, I remain unconvinced.

Lentils Are an Excellent Source of Plant Protein

Protein is one of the major macronutrients and is essential for maintaining muscle, producing enzymes and hormones, supporting immune function and repairing tissues. As we age, maintaining adequate protein intake becomes increasingly important because loss of skeletal muscle contributes to frailty, falls and loss of functional independence.

Lentils provide plant-based protein without the saturated fat that accompanies some animal protein sources.

They are not a complete protein in the same sense as many animal proteins because they are relatively low in certain essential amino acids, particularly methionine. That does not make them nutritionally inadequate. It simply reinforces one of the most important principles of nutrition: variety matters.

A diet containing legumes, whole grains, nuts, seeds and other protein sources can provide all of the essential amino acids the body requires.

There is no physiological rule stating that every individual food must contain everything.

The human diet is a team sport.

Then There Is the Fiber

If lentils have one particularly impressive nutritional characteristic, it is their fiber content.

Dietary fiber is not a single substance but a collection of carbohydrates and other compounds that resist digestion in the small intestine. Some fibers contribute bulk and help maintain normal bowel function. Others are fermented by intestinal microorganisms, producing short-chain fatty acids that participate in gastrointestinal and metabolic physiology.

Lentils contain both soluble and insoluble forms of fiber.

That matters because fiber can slow digestion and carbohydrate absorption, helping to reduce the rapid post-meal rise in blood glucose that can occur with highly refined carbohydrate foods. Fiber also contributes to satiety, which can make it easier for people to regulate their overall food intake.

For someone trying to lose weight or maintain a healthy weight, a bowl of lentils has an entirely different metabolic personality from a bowl of highly refined starch.

The lentils contain protein and fiber, both of which tend to promote fullness. They also have a relatively low glycemic impact compared with many refined carbohydrate foods.

That combination is useful.

Lentils and Blood Sugar

For patients with diabetes or insulin resistance, dietary patterns that emphasize fiber-rich foods, legumes, vegetables, whole grains and minimally processed carbohydrates can be particularly beneficial.

The fiber in lentils slows gastric emptying and carbohydrate absorption, while the protein and complex carbohydrate content contributes to a more gradual postprandial glucose response.

This does not mean that lentils are a treatment for diabetes, nor does it mean someone with diabetes can eat unlimited quantities without considering the carbohydrate content. Lentils still contain carbohydrates and calories.

But compared with many refined carbohydrate foods, they are a much more nutritionally substantial carbohydrate source.

That distinction is important.

Not all carbohydrates are metabolically equivalent.

What About the Heart?

The cardiovascular case for lentils is also fairly compelling.

Legumes are associated with dietary patterns that tend to be higher in fiber and lower in saturated fat. Regular consumption of legumes can contribute to improved lipid profiles and overall cardiovascular health, particularly when they replace foods higher in saturated fat or refined carbohydrates.

The soluble fiber in legumes can bind bile acids in the gastrointestinal tract, encouraging the liver to use cholesterol to synthesize new bile acids. This is one of several mechanisms by which dietary fiber can influence cholesterol metabolism.

Lentils also provide potassium and magnesium, minerals involved in vascular and muscular physiology.

And there is another advantage that gets less attention: lentils are inexpensive enough that eating healthfully does not require a particularly impressive grocery bill.

That is important.

Healthy food should not be treated as a luxury product.

Lentils Bring Iron to the Table

Iron is required for hemoglobin synthesis and oxygen transport, as well as numerous enzymatic reactions throughout the body.

Lentils contain non-heme iron, the form found primarily in plant foods. Non-heme iron is not absorbed as efficiently as heme iron from animal products, and absorption varies according to the rest of the meal and the body’s iron status.

Vitamin C can improve non-heme iron absorption. That means pairing lentils with foods such as peppers, tomatoes, citrus fruits or other vitamin-C-rich produce can be nutritionally advantageous.

There is a broader lesson here that I wish more people understood about nutrition: food combinations matter.

We do not eat isolated nutrients.

We eat meals.

The nutritional effect of a food exists within the context of everything else on the plate.

Magnesium and Potassium

Lentils also provide magnesium and potassium, two minerals with important physiologic roles.

Magnesium participates in hundreds of enzymatic reactions and is involved in muscle contraction, nerve function, glucose metabolism and energy production.

Potassium is essential for normal cellular function and is particularly important for electrical activity in muscle and nerve cells. Adequate dietary potassium is also associated with blood-pressure regulation in healthy individuals.

There is, however, an important medical caveat.

People with significant chronic kidney disease may need to monitor potassium intake depending upon their kidney function and serum potassium level. The fact that lentils are healthy does not mean that every person with every medical condition should eat unlimited quantities of them.

Nutrition is not a morality contest in which a food is either “good” or “bad.”

The right food for one patient may need to be modified for another.

And Then There Is Folate

Lentils are an excellent source of folate, which is particularly important during pregnancy.

Folate is required for DNA synthesis and cell division, making it especially important during periods of rapid cellular growth. Adequate folate status before conception and during early pregnancy reduces the risk of neural tube defects such as spina bifida.

This is one reason folic acid supplementation is recommended for people who could become pregnant.

Lentils are not a substitute for recommended folic acid supplementation, but they can certainly contribute dietary folate to an overall nutritious diet.

Considering that pregnancy involves extraordinarily rapid cellular proliferation, it is hardly surprising that the body becomes particularly interested in folate during those months.

Lentils and the Gut

There is another reason lentils have earned their nutritional reputation: they are food for the microbes living in our gastrointestinal tract.

The human colon contains an enormous community of microorganisms that interact with dietary components, particularly fermentable fibers. When gut bacteria ferment certain fibers, they produce short-chain fatty acids such as acetate, propionate and butyrate.

Butyrate is particularly important for the health of colonic epithelial cells and participates in the regulation of intestinal physiology and immune signaling.

This does not mean lentils will magically “heal your gut,” a phrase that has been stretched far beyond its usefulness on the internet. The human microbiome is complicated, and we are still learning how diet, microbes and host physiology interact.

What we do know is that diets rich in diverse plant fibers support a diverse microbial ecosystem.

And lentils certainly provide fiber.

There Is a Reason Lentils Can Cause Gas

Now we arrive at the one portion of this article where I can offer a little sympathy to the people who share my skepticism about lentils.

Yes, they can cause gas.

Legumes contain fermentable carbohydrates, including oligosaccharides that are not completely digested in the small intestine. When these compounds reach the colon, bacteria ferment them, producing gas.

This is not necessarily a sign that something is wrong. It is often simply the inevitable consequence of feeding bacteria.

People who are not accustomed to eating much fiber may be particularly sensitive when they suddenly consume large amounts of legumes.

The solution is generally to increase fiber gradually, drink adequate fluids and allow the gastrointestinal tract time to adapt. Rinsing canned lentils can also remove some of the compounds responsible for gastrointestinal symptoms.

For some people, however, lentils genuinely cause substantial bloating or abdominal discomfort. Patients with irritable bowel syndrome may be particularly sensitive to certain fermentable carbohydrates, and individualized dietary approaches may be appropriate.

And then there are people like me.

I don’t have a gastrointestinal intolerance.

I simply don’t like lentils.

That is a completely different medical diagnosis.

Dry or Canned?

From a nutritional standpoint, both can be useful.

Dry lentils have an extraordinarily long shelf life and are inexpensive. They require cooking, but unlike some other legumes, lentils generally do not require a prolonged soaking period.

Canned lentils are convenient and can be incorporated into soups, salads, curries and other dishes with minimal preparation.

The primary issue with canned products is sodium. If the product contains added salt, check the label and consider choosing a lower-sodium variety or rinsing the lentils thoroughly before using them.

Rinsing can remove a meaningful portion of the sodium on the surface.

And convenience matters.

The healthiest food in the world is not very helpful if nobody has the time or inclination to prepare it.

Lentils Belong in the Pantry

From a purely practical standpoint, lentils are almost impossible to criticize.

They are inexpensive.

They store well.

They require little preparation.

They provide protein.

They provide fiber.

They contain folate, iron, magnesium and potassium.

They can be incorporated into soups, stews, curries, salads and grain dishes.

Cooked lentils can also be refrigerated or frozen for later use.

That makes them an excellent pantry staple, particularly for people trying to eat more plant-based foods without spending a fortune.

My wife, naturally, is a fan.

I suspect she is enjoying the fact that I am now writing an entire article praising the food I have spent most of my life avoiding.

My Lentil Problem

I should probably confess something else.

There is a peculiar psychological phenomenon that happens with food memories. Taste and smell are closely connected to emotional and autobiographical memory, and a food associated with a particularly unpleasant experience can trigger a surprisingly powerful response years later.

That is probably what happened to me.

I don’t remember every meal I ate as a child. I certainly don’t remember every vegetable my mother served. But I remember sitting at that table with a bowl of lentils and being told, in effect, that the battle would end only when the bowl was empty.

Apparently, my brain decided to archive that experience permanently.

So now, decades later, lentils can walk into a room and my gastrointestinal tract apparently files an objection.

This is not evidence that lentils are unhealthy.

It is evidence that childhood food trauma has an excellent memory.

The Verdict

If I were counseling a patient who asked me whether lentils were a nutritious food, my answer would be unequivocal: yes.

They are an excellent source of plant protein and dietary fiber. They provide folate, iron, magnesium and potassium. Their high fiber content can support gastrointestinal health, satiety and healthier glucose regulation. As part of an overall healthy dietary pattern, legumes such as lentils can contribute to cardiovascular health and may help replace foods higher in saturated fat or refined carbohydrates.

They are inexpensive, versatile and remarkably easy to keep in the pantry.

They are, by virtually every nutritional measure, a very good food.

I simply will not eat them.

That distinction matters because physicians are human beings too. We have preferences, childhood memories, irrational dislikes and foods that we would happily never see again. My job as a physician is not to make every patient eat what I personally enjoy. My job is to understand the evidence, explain what it means and help patients make informed decisions.

So, in the interest of fairness, I am willing to say this publicly:

Lentils are good for you.

There. I’ve done my duty.

I will continue to leave them to my wife.

And if Sadie wants lentils for dinner, I will happily prepare something else.

Medicine teaches us to separate personal experience from evidence. In this particular case, the evidence has won the argument.

The lentils, however, are still not getting anywhere near my plate.

Grow Strong: Why Gardening May Be One of the Best Workouts in Your Own Backyard

Living in rural Glocester, Rhode Island, has its advantages, particularly if you happen to enjoy having dirt underneath your fingernails. Sadie and I live on 65 acres, and with that much land there is always something growing, something that needs pruning, something that needs cutting back, something that needs watering, or, in the case of this particular time of year, something that is finally ready to be harvested. We garden quite a bit, and this year’s harvest has been remarkable. This past weekend, while we were out harvesting vegetables from the gardens, I found myself thinking about how easily gardening gets categorized as a chore when, physiologically speaking, it can be a rather impressive workout.

We tend to have a peculiar definition of exercise in modern life. If someone tells us they exercised, we imagine a gym, a treadmill, a stationary bicycle, a rack of dumbbells or perhaps somebody performing a complicated sequence of movements while a fitness instructor shouts encouragement. There is certainly nothing wrong with any of those things, but they are not the exclusive domain of physical fitness. The human body was not designed around the assumption that exercise would occur for precisely forty-five minutes under fluorescent lights before we returned to sitting for the remaining fifteen hours of the day.

For most of human history, physical activity was simply part of living. People walked, carried things, lifted things, squatted, climbed, dug, chopped, hauled, planted and worked with their hands. Gardening happens to bring many of those movements back into ordinary life. Digging requires force from the legs, hips, back and upper extremities. Pulling weeds recruits the shoulders, arms, abdominal muscles and back. Pushing a wheelbarrow involves the legs and trunk while requiring the upper body to stabilize and propel the load. Raking involves repeated movement of the shoulders and torso. Carrying soil, mulch, watering cans or baskets of vegetables becomes resistance exercise in a very practical disguise.

And then there is the walking. Anyone who has maintained a substantial garden knows that gardening involves a surprising amount of walking back and forth because the tool you need is invariably sitting approximately thirty feet away from where you are standing.

That may not be a bad thing.

Gardening Is Exercise, Even If You Don’t Call It Exercise

The Centers for Disease Control and Prevention has long emphasized the importance of regular physical activity because exercise is associated with lower risks of cardiovascular disease, hypertension, stroke, type 2 diabetes, osteoporosis, depression and several cancers, as well as lower risk of premature death. Physical activity also improves sleep, insulin sensitivity, physical function and overall quality of life.

The important point is that physical activity does not have to arrive wearing athletic shoes.

Gardening can contribute to the weekly accumulation of moderate-intensity physical activity, depending upon what you are doing and how vigorously you are doing it. Mowing, digging, planting, weeding, raking, hauling and other forms of yard work can raise the heart rate and increase energy expenditure. The exact number of calories burned varies substantially with body size, age, fitness level, terrain, weather and the intensity of the work, so I am always somewhat suspicious when someone gives me a beautifully precise number for “calories burned gardening.” Human metabolism is not a lawn mower with a standardized fuel consumption rating.

Still, the principle is sound: gardening can require meaningful physical effort.

Digging and turning soil are particularly good examples. You are not simply moving a shovel through dirt. You are generating force through the feet and legs, transferring that force through the hips and trunk, stabilizing the spine and shoulders and then using the arms to control the tool. Repeated over an hour, that is substantial muscular work.

Raking requires repetitive shoulder and upper-back movement, while pushing a wheelbarrow requires both strength and balance. Carrying bags of soil or baskets of vegetables adds an obvious resistance component. Squatting to plant or weed engages the quadriceps, hamstrings and gluteal muscles and can be a much better functional movement than spending an afternoon hunched over on your knees.

There is also a cardiovascular component. If you maintain a steady pace, your heart rate rises, your breathing becomes deeper and your muscles require increased oxygen delivery. In other words, your cardiovascular system recognizes gardening as exercise even if your smartwatch is confused about what activity to label it.

The Garden Can Become a Strength-Training Facility

One of the most useful things about gardening is that it incorporates functional strength.

As a trauma and critical care surgeon, I spend a fair amount of time thinking about what happens when people lose physical capacity. Strength is not merely about how much weight someone can lift in a gym. It determines whether someone can rise from a chair, climb stairs, carry groceries, get up after a fall, lift a grandchild or maintain independence as they age.

Gardening uses the same basic movement patterns that matter in everyday life.

When you squat to plant something, you are practicing a movement pattern that requires strength and coordination through the hips, knees and ankles. When you lift a bag of soil, you are training the muscles that stabilize your trunk while moving a load. When you push a wheelbarrow, you are coordinating the upper and lower body while maintaining balance. When you carry a basket of vegetables from the garden back to the house, you are performing a loaded carry, one of the simplest and most useful forms of functional exercise.

There is a caveat, however: functional exercise still requires good mechanics.

A 40-pound bag of soil does not become weightless simply because it has the word “garden” printed on it.

When lifting, keep the load close to your body, bend through the hips and knees rather than rounding excessively through the lower back, and avoid twisting while carrying a heavy object. If something is awkward or too heavy, get help. There is very little virtue in throwing out your back because you were determined to demonstrate to a bag of mulch who was in charge.

Don’t Kneel When You Can Squat

One of the simplest ways to turn gardening into better exercise is to pay attention to how you move.

Instead of remaining kneeling or folded at the waist for an extended period, periodically squat, stand and change position. A controlled squat engages the large muscles of the thighs and hips and challenges balance. Those are precisely the muscles that become increasingly important as we age.

That does not mean you should squat continuously for an hour. The point is variety.

One of the recurring problems with gardening is that people find themselves in the same posture for long periods. They bend over to weed, straighten up, bend over again and repeat the process hundreds of times. The result is predictable: sore lower backs, stiff hips and angry knees.

Change positions. Stand up. Walk around. Stretch. Switch tasks. Use a kneeling pad when kneeling makes sense. Raise planting beds when appropriate. Good gardening technique is ultimately good biomechanics.

Don’t Do the Same Thing for an Hour

If I were designing a gardening workout, I would actually steal an idea from physical therapy: vary the movement.

Dig for a while, then weed. Move from weeding to planting. Rake for a period and then walk while carrying something light. Prune, then take a short walk. Work in one area and then move to another.

Changing tasks distributes the physical load among different muscle groups and reduces the amount of repetitive stress placed on a particular joint or tendon.

It also keeps the activity interesting.

The body responds to movement, not monotony.

For someone who has not exercised regularly, there is no reason to spend the first day in the garden trying to reclaim an acre from nature. Start with a manageable amount of work and gradually increase duration and intensity. Thirty minutes of moderate activity is a perfectly respectable starting point, and the work can be accumulated in smaller periods throughout the day.

For someone already accustomed to physical activity, gardening may provide a surprisingly demanding workout.

The difference is usually intensity.

Pulling one stubborn weed from loose soil is not cardiovascular training. Pulling a wheelbarrow full of soil uphill in August is a different conversation.

Warm Up Before You Start Digging

People frequently assume that because gardening is not formally classified as exercise, they do not need to prepare for it.

Your muscles do not care what you call the activity.

If you are going to spend several hours digging, raking, lifting and hauling, spend a few minutes moving first. A brisk walk around the property is an excellent warm-up. Gentle dynamic movements of the hips, shoulders and ankles can also help prepare the body for the work ahead.

I prefer dynamic movement before physical activity rather than immediately beginning with prolonged static stretching. Save much of the longer stretching for afterward, when the muscles are warm.

And if your first day of serious gardening each spring results in every muscle in your body hurting for two days, that is not necessarily a sign that you had an excellent workout. It is often a sign that you dramatically exceeded what your body was prepared to do.

There is a difference between productive soreness and injury.

Your Heart Gets a Workout Too

Gardening can also be useful cardiovascular exercise, particularly when the work is performed continuously enough to elevate the heart rate.

A useful practical measure is the talk test. During moderate activity, you should generally be able to speak but not comfortably sing an entire song. If you are completely breathless, dizzy or struggling to communicate, you may be working too hard.

People with known cardiovascular disease, significant pulmonary disease, poorly controlled hypertension or other medical conditions should discuss exercise recommendations with their physician.

And there is one point I would emphasize particularly strongly for older adults: do not underestimate the cardiovascular stress of outdoor work.

Hot weather, dehydration and heavy exertion can place considerable strain on the cardiovascular system. Someone can feel perfectly healthy sitting in the shade at 9 a.m. and become substantially more physiologically stressed after two hours of digging in the afternoon sun.

Heat changes the equation.

Gardening Is Medicine for the Mind, Too

The physical benefits are only part of the story.

There is something psychologically different about working with soil.

Modern life is extraordinarily good at keeping us connected to devices and remarkably poor at allowing us to be disconnected from them. We carry computers in our pockets, receive notifications throughout the day, answer messages while walking and spend enormous portions of our lives looking at screens.

A garden requires something else.

You have to look at what you are doing.

You notice the soil, the leaves, the insects, the temperature, the weather and the subtle differences between one plant and another. You become aware of time in a different way. Plants do not care about email. Tomatoes do not respond to text messages. A cucumber does not care whether you have checked the news in the last fifteen minutes.

There is something wonderfully corrective about that.

Gardening can be relaxing, and time spent outdoors can provide psychological benefits independent of the physical work itself. Physical activity also influences neurotransmitter systems involved in mood and stress regulation, while exposure to natural environments has been associated with improvements in perceived stress and well-being.

I would not describe gardening as a substitute for treatment of clinical depression or an anxiety disorder. Mental illness deserves proper medical care. But there is considerable wisdom in incorporating ordinary physical activity, sunlight, nature and purposeful work into our lives.

Sometimes the brain benefits from doing something that produces a tangible result.

At the end of several hours in the garden, you can look behind you and actually see what you accomplished.

That is increasingly rare in modern work.

There Is Another Benefit: You Get to Eat the Workout

One of the great pleasures of gardening is that the reward is not merely an elevated heart rate.

You get vegetables.

There is something particularly satisfying about harvesting food that began as a seed, tended throughout the season and eventually arrived on the dinner table. Gardening can also make healthy food more tangible. A person who has spent months growing tomatoes, peppers, squash, beans or leafy vegetables has a rather different relationship with those foods than someone who encounters them exclusively in plastic packaging at the grocery store.

The nutritional benefits of a diet rich in vegetables are well established. Vegetables provide fiber, potassium, folate, vitamin C, carotenoids and a broad assortment of phytochemicals. Eating more vegetables can displace highly processed foods and contribute to a healthier overall dietary pattern.

In our case, the garden has become part of the rhythm of the year. We plant, tend, wait, harvest and then figure out what on earth we are going to do with all of it.

That last part is sometimes the most difficult.

Protect Your Skin While You Work

There is, however, one medical downside to spending hours outdoors that gardeners should take seriously: ultraviolet radiation.

Years of cumulative sun exposure contribute to premature skin aging and increase the risk of skin cancers, including basal cell carcinoma, squamous cell carcinoma and melanoma.

Wear a broad-brimmed hat or another protective covering, use sunscreen on exposed skin and remember areas that are routinely forgotten, particularly the ears, back of the neck, forearms and hands. Sunscreen should be reapplied according to the product directions and after sweating heavily or swimming.

The fact that you are doing healthy physical activity does not make ultraviolet radiation healthier.

The sun remains the sun.

Don’t Forget the Ticks

Anyone gardening in Rhode Island also needs to think about ticks.

We live in an area where tick-borne diseases are not theoretical problems. Lyme disease is well established in New England, and other tick-borne illnesses occur in the region as well.

Wear appropriate clothing when working in tall grass, brush or wooded areas, consider an EPA-registered insect repellent when appropriate, and perform a tick check after spending time outdoors. Check the scalp, behind the ears, waistline, groin, armpits and behind the knees, along with the rest of the body.

Gardening gloves protect the hands, but they do not constitute a complete tick-defense strategy.

Neither does optimism.

Hydration Matters More Than You Think

Bring water into the garden.

It sounds almost embarrassingly obvious, yet people routinely become dehydrated while working outside because they become absorbed in the task and fail to notice how much they are sweating.

Thirst is a useful physiologic signal, but during prolonged activity or hot weather it should not be the only thing you consider. Drink regularly, particularly in heat and humidity, and pay attention to symptoms such as headache, weakness, dizziness, nausea, unusual fatigue or confusion.

Heat illness can progress rapidly. Confusion, altered mental status, collapse or severe neurologic symptoms in someone who has been exerting themselves in hot conditions should be treated as a medical emergency.

There is also no prize for drinking enormous quantities of plain water. Excessive water intake during prolonged exercise can contribute to exercise-associated hyponatremia, in which blood sodium becomes dangerously diluted. Hydration should be sensible rather than competitive.

Protect Your Hands, Knees and Back

A few inexpensive pieces of equipment can make gardening substantially more comfortable.

Gardening gloves protect the hands from blisters, thorns, splinters, soil and minor skin injuries. A padded kneeling mat can reduce pressure on the knees. Properly sized tools can reduce strain on the wrists and hands, and long-handled tools may be useful for people who have difficulty bending or kneeling.

And when you are moving heavy materials, use a wheelbarrow or garden cart rather than trying to carry everything yourself.

The wheelbarrow is one of the great inventions of civilization.

Use it.

Be Careful With Chemicals

Gardeners should also remember that fertilizers, pesticides, herbicides and other lawn and garden products are chemicals, not magical substances.

Follow the product label. Use appropriate protective equipment when required. Do not mix products unless the instructions specifically permit it. Store chemicals securely and away from children and pets. Wash your hands after handling them, and do not assume that more product means better results.

It usually means more exposure.

If you are using pesticides, pay attention to instructions concerning re-entry intervals and edible crops. Organic does not automatically mean harmless, either. Many naturally occurring substances are biologically active, and some can be toxic.

Gardening Is Exercise, But It Is Not a Complete Exercise Program

There is one important qualification to all of this enthusiasm.

Gardening is wonderful exercise, but it should not necessarily be the only exercise you do.

Current physical-activity recommendations emphasize a combination of aerobic activity and muscle-strengthening exercise. Gardening can contribute to both, but the intensity and movement patterns vary considerably from day to day.

A day spent hauling compost may be physically demanding. A day spent sitting on a garden stool pulling tiny weeds may not provide much cardiovascular stimulation at all.

For a complete fitness program, I would still encourage regular aerobic activity, resistance training and exercises that challenge balance and mobility, particularly as people get older.

But gardening can absolutely be part of that equation.

And for someone who hates gyms, that distinction can be transformative.

Listen to Your Body

Perhaps the most important rule is the least complicated: pay attention to what your body is telling you.

Muscle fatigue is normal. Mild soreness after unfamiliar activity can be normal. Sharp pain, chest pressure, significant shortness of breath, fainting, severe dizziness or neurologic symptoms are not things to “work through.”

Stop.

People sometimes become surprisingly stubborn when working outdoors. There is something about a garden that encourages the mentality of “I’ll just finish this row.” The problem is that your cardiovascular system, lumbar spine and rotator cuff have absolutely no interest in whether the row gets finished.

If you feel unwell, stop the activity and assess what is happening. If symptoms suggest a medical emergency, seek medical care rather than trying to finish the tomatoes.

The tomatoes will survive.

Grow Something, and Grow Strong

There is an old-fashioned quality to gardening that I find increasingly appealing. It is exercise without the branding, food without the packaging and recreation without a screen. It requires physical effort, patience and a willingness to accept that nature does not operate according to our preferred schedule.

For Sadie and me, living on 65 acres means there is always work to be done. The gardens are only one part of it, but they are among the most rewarding. This year’s harvest has been particularly good, and as we gathered vegetables this past weekend, I was reminded that the garden gives us considerably more than food.

It gives us movement.

It gives us time outside.

It gives us a reason to bend, squat, lift, carry, push, pull and walk.

It gives us sunlight, fresh air and a welcome break from the machinery of modern life.

And, perhaps most importantly, it gives us something tangible at the end of the work.

You can stand there with a basket of vegetables in your hands and know that the hours of digging and planting produced something. The muscles got a workout, the heart got moving, the mind got a break, and dinner is sitting there in a basket.

That is a pretty good exercise program.

You just have to remember to drink some water, put on sunscreen, check yourself for ticks and stop before you decide that one more wheelbarrow load of mulch is worth an emergency department visit.

Because gardening should make you grow strong.

It should not make you become a patient.
