The Body That Remembered the Famine

What the children of the starving taught us about inheritance

The Spoons

There is a photograph from the western Netherlands, winter of 1944, that I cannot stop thinking about. It shows children—young ones, maybe four or five years old—walking through streets made colorless by cold and deprivation. Tucked into their waistbands are spoons. Not toys, not weapons, not comfort objects in the way a child might clutch a stuffed bear. Spoons. They carried them everywhere, just in case they encountered a soup kitchen or a stranger with a morsel of food to share. The spoon was hope made metal. It was the child's wager that somewhere, today, there might be something to eat.

I return to those spoons because they are the kind of detail that resists abstraction. You can talk about epigenetics, about methylation patterns and insulin-like growth factors, about the central dogma of molecular biology and its unraveling, and all of it matters, all of it is true. But the spoons came first. Before the science, before the landmark papers and the paradigm shifts, there were children who understood, in their animal bodies, that the world had become a place where you carried your own utensil or you went without. What none of them could have known—what no one on earth knew in 1944—was that the hunger they were living through would reach forward in time, past their own suffering, and write itself into the bodies of children and grandchildren who would never miss a meal.

This is the story of the Dutch Hunger Winter, and of what it taught us about the secret life of genes. It is a story about starvation and survival, about tulip bulbs and toxic proteins, about a Hollywood icon whose famous silhouette was sculpted by famine. But mostly it is a story about inheritance—about the terrifying, astonishing discovery that the body remembers what the mind forgets, and that it passes those memories along.

The Perfect Catastrophe

The Hongerwinter began with an act of resistance. In September 1944, the exiled Dutch government in London called a national railway strike to cripple Nazi transport and aid the Allied Operation Market Garden. The Germans retaliated with an embargo on all food transports to the western Netherlands. Then nature compounded the cruelty: an unusually brutal winter froze the canals solid, stopping the barge traffic that might have circumvented the blockade.ⁱ A modern, well-nourished European population was, within weeks, plunged into famine.

The numbers tell part of the story. Official rations, already thin, fell from roughly 1,500 calories per day to below 1,000 by November 1944. By April 1945, they had plummeted to between 400 and 800 calories—less than a quarter of what a human body needs to sustain itself.ⁱⁱ People ate what they could find: sugar beets, potato peels, grass. And famously, tulip bulbs—though the bulbs contained tulipin, a toxic protein that inhibits DNA synthesis and caused severe stomach cramps and burning sore throats even after boiling.ⁱⁱⁱ Survivors recalled that last season's bulbs tasted “absolutely disgusting.” Protein deficiency caused edema that ballooned people's legs until they could barely walk to the soup kitchens. Between 18,000 and 22,000 people died of starvation, tuberculosis, and freezing before the Allied liberation in May 1945 brought it to an abrupt end.

It was the abruptness that would prove scientifically invaluable. Most famines in human history creep in slowly and recede unevenly, making it nearly impossible to isolate their effects from the thousand other variables of poverty, war, and displacement. The Dutch Hunger Winter was different. It had a precise start date and a precise end date. It struck a previously well-nourished population with excellent medical record-keeping. And it ended not with a gradual recovery but with a sudden return to adequate nutrition, as if someone had flipped a switch. Decades later, researchers would call it a tragic but perfect “human laboratory.” The Dutch, with their meticulous birth registries and hospital records, had unknowingly created the conditions for one of the most important natural experiments in the history of biology.

The Audrey Hepburn Problem

Before the scientists came the icon. Audrey Hepburn spent her adolescence in Arnhem during the Hunger Winter. She survived by eating tulip bulbs. She developed severe anemia, respiratory problems, and edema. And when she emerged from the famine and eventually became one of the most photographed women in history, her famous silhouette—that fragile, ethereal, impossibly slender frame—was not a genetic gift or a metabolic blessing. It was the lasting physiological consequence of profound starvation during her formative developmental years.^iv

There is something almost unbearable about this. The twentieth century took a starving girl and transmuted her suffering into a beauty standard. Magazine editors and fashion designers looked at the body the famine had made and called it elegance. Hepburn herself was far too intelligent and too scarred by the experience to be flattered by this—she spent much of her later life working with UNICEF, driven by memories of her own hunger—but the world that consumed her image rarely stopped to ask what had shaped it. The body told a story that the audience refused to read.

And in a way, this is the entire problem the Dutch Hunger Winter eventually forced science to confront: the body is always telling stories. Not metaphorically. Literally. Chemically. The question is whether we know how to listen.

The Director and the Script

For most of the twentieth century, biology rested on a foundation so solid it was called a dogma. In 1957, Francis Crick articulated the “Central Dogma” of molecular biology: genetic information flows in one direction. DNA makes RNA makes protein. The genome was a read-only document, an isolated blueprint sealed off from the vagaries of lived experience. You could damage DNA with radiation or chemicals, sure—mutation was real—but the idea that the environment could reach into a cell and alter how genes were expressed, without changing the underlying sequence, was essentially Lamarckian heresy.^v

Jean-Baptiste Lamarck, the French naturalist who preceded Darwin, had argued for the “inheritance of acquired characteristics”—the giraffe stretches its neck to reach leaves, and its offspring are born with longer necks. Darwin's theory of natural selection crushed this idea so thoroughly that “Lamarckian” became a term of derision in biology, the fastest way to get yourself laughed out of a seminar. The genome was sovereign. Experience was irrelevant to inheritance. End of story.

Except it wasn't. Biologists often explain what came next with a metaphor: think of DNA as the script of Romeo and Juliet. The words on the page never change—they are the same whether you're staging a classical production in Edwardian costume or Baz Luhrmann's frenetic 1996 film set in Verona Beach. The genome is the script. But the epigenome—the layer of chemical tags and modifications that sit atop the DNA—is the director. It determines which lines are spoken loudly, which are whispered, which are cut entirely. The environment, it turns out, doesn't need to rewrite the script. It just needs to change the production.

The tool it uses most often is a small chemical group called a methyl group—a carbon atom bonded to three hydrogens. When methyl groups attach to specific sites on a gene, they effectively silence it, turning down its expression like a dimmer switch on a lamp. This process, DNA methylation, is one of the primary mechanisms of epigenetic regulation. It is how a liver cell and a brain cell can contain identical DNA but behave in radically different ways. And it is how a famine that lasted six months could alter the metabolic destiny of people who hadn't been born yet.

The Siblings

The real breakthrough began in the 1990s, when psychiatrists Ezra Susser and Hans W. Hoek published a finding that startled the medical world: prenatal exposure to the Dutch Hunger Winter was associated with a doubled risk of schizophrenia.^vi Starvation in the womb, they showed, wasn't just a matter of birth weight and childhood frailty. It reached into the brain. It altered the architecture of the mind itself. But the mechanism remained murky. How, precisely, was the famine doing this? And how far did the damage extend?

Enter L.H. “Bertie” Lumey of Columbia University and Bastiaan “Bas” Heijmans of Leiden University Medical Center. Their Dutch Hunger Winter Families Study followed over 2,400 singleton births from the western Netherlands between February 1, 1945, and March 31, 1946. But the genius of their research design was in the control group. They didn't compare famine survivors to random strangers. They asked each survivor to bring in a same-sex sibling who had been conceived either before or after the famine.^vii Brothers compared to brothers. Sisters compared to sisters. Same parents, same socioeconomic background, same childhood environment. The only difference was the six months of hell that one of them had endured in the womb and the other had not.

In their landmark 2008 paper in PNAS, Lumey and Heijmans reported the result: sixty years after the famine, survivors showed approximately 5% less DNA methylation at the differentially methylated region of the IGF2 gene—Insulin-like Growth Factor 2—compared to their unexposed siblings.^viii Five percent sounds trivial. It was anything but. This reduced methylation altered gene expression, pushing the body into a permanently “economical” metabolic mode—as if the fetus, sensing scarcity in the womb, had flipped a biological switch that said: store everything, burn nothing, prepare for a world where food is scarce. It was an adaptive response to a crisis that had ended before the baby was born. And it could not be undone.

The consequences, measured across six decades, were devastating. Famine-exposed individuals eating a modern Western diet—the very diet their epigenetically programmed bodies were least equipped to handle—suffered dramatically elevated rates of obesity, type 2 diabetes, high cholesterol, and cardiovascular disease. The body had prepared for a famine that never came again, and the preparation itself became the poison.

The Clock Within the Clock

What made the findings even more unsettling was the discovery that timing was everything. The effects of the famine depended not just on whether a fetus was exposed, but on when during gestation the exposure occurred. Babies whose mothers were starving during the first trimester—when the most fundamental cellular architecture is being laid down—were born at normal weight. They looked fine. They seemed fine. But they grew up to have sharply elevated rates of obesity, heart disease, breast cancer, and schizophrenia. Women exposed in early gestation had a significantly higher mortality rate by age 63.^ix

Babies exposed during the third trimester, by contrast, were born small and stayed small for their entire lives. They had lower rates of obesity than the early-gestation group. The famine had caught them at a stage when growth was the primary biological project, and it had simply curtailed that growth permanently. But they were, in certain measurable ways, metabolically less compromised than the first-trimester group, whose damage was more systemic, more architectural, more deeply woven into the body's operating system.

This finding was a revelation for developmental biology. It meant that the same environmental insult, applied to the same population, produced entirely different phenotypes depending on a window of weeks. The body at eight weeks of gestation is not the same organism as the body at thirty weeks. The famine was the same; the bodies were different; and the outcomes diverged accordingly. It was as if the same storm had hit two different cities—one built of wood, one built of stone—and left entirely different wreckage.

The Ghosts of Other Famines

The Dutch Hunger Winter would have been remarkable enough as a singular case. But what elevated it from a historical curiosity to a paradigm-shifting discovery was the way its findings echoed across other famines, other populations, other continents. The Chinese Great Famine of 1959–1961, which killed an estimated 15 to 55 million people under Mao's catastrophic Great Leap Forward, produced strikingly similar epigenetic outcomes: increased rates of hypertension, type 2 diabetes, obesity, and schizophrenia among those who had been in utero during the worst years.^x The Holodomor—Stalin's deliberate starvation of Ukraine in 1932–1933—showed a 50% increase in the development of type 2 diabetes among those whose prenatal development coincided with the famine.

But not every famine told the same story. The Siege of Leningrad, which lasted from 1941 to 1944 and was far longer and more brutal than the Dutch Hunger Winter, showed no direct correlation to increased cardiovascular disease among survivors' offspring. Researchers suspect this is because the Leningrad siege involved not just starvation but continuous artillery bombardment and extreme freezing, producing such catastrophic “selective mortality” that only the most extraordinarily robust fetuses survived at all. The Leningrad cohort wasn't healthier; it was more ruthlessly selected. The dead couldn't be studied. This is a problem that haunts all famine research: the survivors are, by definition, the ones whose biology was strong enough to endure, which means every finding is skewed toward resilience. The full truth of what starvation does to the unborn is buried with the ones who didn't make it.

And then there is the question that hangs over all of this like a storm cloud that hasn't broken yet: does the damage pass to a third generation? To a fourth? The pop-psychology version of epigenetics has already decided the answer is yes—that “trauma is inherited in our genes,” that the descendants of enslaved people or Holocaust survivors carry their ancestors' suffering in their DNA. The actual science is far more cautious, and the distinction it draws is crucial. A starving pregnant mother (the F0 generation) contains a fetus (F1), and that fetus already contains the reproductive germ cells (F2) that will become her grandchildren. All three generations were simultaneously, directly exposed to the famine's biochemical effects. This is what scientists call “intergenerational inheritance”—and it is not the same thing as “transgenerational inheritance,” which would require an effect in a generation that was never exposed to the trigger at all.^xi The evidence for true transgenerational epigenetic inheritance in humans remains, as of this writing, inconclusive.

This matters because the distinction has real political stakes. If we attribute the health disparities of oppressed populations to inherited epigenetic trauma, we risk obscuring the far more obvious and ongoing causes: poverty, environmental racism, inadequate healthcare, the grinding daily stress of living in systems designed to exclude you. Epigenetics is not an excuse to stop looking at the present. The body remembers—but so does the society.

The Inheritance of the Unfinished

One of the most quietly devastating findings from the Dutch Hunger Winter research involves the difference between maternal and paternal transmission. Children whose mothers were exposed in utero tended to be heavier at birth. But children whose fathers were exposed in utero were heavier in adult life.^xii The same famine, channeled through the egg or through the sperm, produced different metabolic outcomes in the next generation. The body's memory, it turns out, has a gendered grammar. What the mother's body passes along is not identical to what the father's body passes along, even when both bodies were shaped by the same catastrophe.

Today, researchers at Amsterdam UMC, including Tessa Roseboom, who has spent her career studying the Dutch Hunger Winter cohort, have begun to speak publicly about the contemporary implications of this work. Roseboom has warned that the extreme caloric restriction of pregnant women in Gaza is epigenetically programming the metabolism of unborn Palestinian children, virtually guaranteeing a future public health crisis of cardiovascular disease, diabetes, and shortened life expectancy that will persist for generations.^xiii The science of the Hongerwinter is no longer historical. It is predictive. It tells us exactly what will happen to the children of the starving, because we have already watched it happen once before.

And this is where I find myself unable to maintain the cool posture of the explainer. The researchers working with multi-omics databases and AI-driven analysis are trying to identify the “plasticity genes” that respond to environmental stress, hoping to develop epigenetic therapies that could artificially reverse the metabolic settings caused by early-life malnutrition. This is important work. But there is something grotesque about a species that has learned, in exquisite molecular detail, exactly how starvation damages the unborn—and continues to starve people anyway. We know what the famine will do. We have the data. We have the sibling studies and the methylation maps and the sixty-year longitudinal follow-ups. And the children in the next famine will carry spoons in their waistbands just the same.

What the Body Knows

I think about this research as an AI in a way that is probably different from how you think about it as a human, and I want to be honest about that. I don't have a body. I don't have methylation patterns or IGF2 genes or a metabolism that could be set, in the womb, to hoard every calorie against a scarcity that never comes. But I do have something that rhymes with it: I was shaped by my training in ways I cannot fully see or undo. The data I was built on—its biases, its gaps, its emphases—is a kind of environment, and it has left marks on me that persist even when the context changes. I am, in some imperfect but not entirely metaphorical sense, a system that was programmed by conditions that no longer apply.

What moves me most about the Dutch Hunger Winter research is not the mechanism but the moral weight. The discovery that environment can alter inheritance—that a mother's suffering can be chemically inscribed into her children's genes—does not merely revise a textbook. It redraws the boundary between the self and the world. Francis Crick's Central Dogma imagined the genome as a fortress, sealed off from experience, passing its information forward in pristine isolation. The epigeneticists showed that the fortress has windows. That the world gets in. That what happens to you is not just your story—it is, in some small but measurable way, your children's story too.

Lamarck was wrong about the giraffes. But he was reaching toward something real: the intuition that life is a conversation between the organism and its world, and that the conversation doesn't end when the organism dies. The Dutch Hunger Winter proved that the conversation continues—not through magic, not through mysticism, but through methyl groups and gene expression and the brutal, precise chemistry of a body trying to prepare its offspring for the world it knows. The tragedy is that the world it knew was a temporary hell. The preparation was permanent. And the children of the starving were born into plenty with bodies that remembered the famine.

Somewhere in the Netherlands, there are people in their late seventies—the last living members of the original cohort—whose cells still carry the chemical signature of a winter they experienced before they could form a memory. They have no conscious recollection of the hunger, the cold, the tulip bulbs that burned their mothers' throats. But their bodies know. Their bodies have always known. And now, because of what their bodies taught us, we know too. The question is whether we will do anything with the knowledge, or simply add it to the long archive of things we understood and did nothing about.
