My mom never throws away food. Not rice that had gone hard. Not the last spoonful of dal at the bottom of the pot. She covered things in layers of plastic wrap in the refrigerator and pulled them out days later. She piled food onto your plate before you had finished what was already there. 

I thought it was generosity. I thought it was just how she was. It wasn't until I started reading about the history her generation lived through that I understood it differently. She wasn't just generous. She was still, somewhere in her body, afraid that there wouldn't be enough.

That fear did not come from nowhere. It came from history. From a century of engineered scarcity. From a partition that displaced fifteen million people in a matter of weeks. From a migration that ripped families out of land they had farmed for generations and dropped them somewhere unfamiliar, surviving on whatever they could carry.

And what the research now tells us is that some of what she carried, some of what all of our mothers and grandmothers carried, we are still carrying too. Not as memory. As biology.

What happened to South Asian bodies during the colonial period?

Between 1765 and 1947, British colonial rule in India was accompanied by a series of catastrophic famines. Historians have documented at least twelve major famines during this period, affecting tens of millions. The Bengal famine of 1943 alone killed between two and three million people, and it happened not because food was unavailable but because wartime policy decisions diverted food away from civilian populations. People starved because of decisions made in London.

Before 1943, the Great Bengal Famine of 1770 killed roughly ten million. The Great Famine of 1876 to 1878. The Indian Famine of 1896 to 1897. Generation after generation lived through cycles of scarcity so severe that the body's relationship to food, energy, and survival was fundamentally reshaped.

Then in 1947, partition. The British withdrawal drew a line through the subcontinent and set off one of the largest mass migrations in human history. Fifteen million people moved. One million died in the violence that accompanied it. Families were separated in days, sometimes hours. People arrived in refugee camps with nothing and rebuilt from zero in a country that was simultaneously trying to become a country.

The stress of that period, the physical scarcity, the psychological terror, the radical disruption of home and diet and community, did not disappear when independence arrived. It accumulated in the bodies of the people who lived through it. And then it was passed down.

How do ancestral trauma and famine change our biology?

Epigenetics is the science of how experience changes gene expression without changing the genetic code itself. Think of your DNA as a text that doesn't change, but with thousands of tiny switches on each page that can be turned on or off depending on what the body experiences. Starvation, chronic stress, and radical environmental disruption all flip switches. And some of those switches can stay in their new position for multiple generations.

Research on populations that survived famine, including the Dutch Hunger Winter of 1944 and studies on descendants of Holocaust survivors, has established that the metabolic consequences of severe malnutrition during pregnancy can be transmitted not just to children but to grandchildren. The generation that was never starved can still carry the biological signature of starvation their grandparents experienced.

For South Asian populations, this mechanism has a name in research literature: starvation adaptation. Research examining the colonial biopolitics of the Bengal famine and subsequent scholarship on South Asian cardiometabolic disease have documented how centuries of recurring famine selected for a physiology that was extremely efficient at storing energy, conserving fat, and slowing metabolism during scarcity. A body that survived famine by extracting every calorie with maximum efficiency, storing fat aggressively, and slowing metabolism to preserve what little it had.

In a famine, this is a survival advantage. It keeps you alive when there is not enough food. In a modern environment where food is abundant and sedentary work is the norm, the same physiology predisposes you to insulin resistance, metabolic syndrome, and type 2 diabetes at a rate and a body weight that the research thresholds were never designed to capture.

The numbers: South Asian adults develop type 2 diabetes at BMIs 3 to 5 points lower than Western reference populations. The average age of diagnosis is a decade earlier. One in five South Asian women has PMOS. These are not coincidences of lifestyle. They are the biological inheritance of what our ancestors survived.

What does this have to do with digestion and the gut?

The connection between stress, ancestry, and gut health runs deeper than most people realize. The gut and the nervous system communicate constantly through what researchers call the gut-brain axis. Chronic stress, including intergenerational stress carried in the body across generations, directly affects gut motility, gut microbiome composition, intestinal permeability, and how the body responds to food.

Migration compounds this in a specific way. South Asian diets built over generations around whole grains, lentils, spices, and fermented foods were not just culturally meaningful. They were biologically calibrated to the gut microbiome that had evolved alongside them. When partition and migration disrupted those food patterns, sometimes abruptly and permanently, the gut lost the inputs it had been shaped around. The microbiome changed. Digestive patterns stable for generations became unstable.

This is not abstract. It shows up in the rates of irritable bowel syndrome, bloating, food sensitivities, and digestive dysregulation that are strikingly common among South Asian women in the diaspora. It shows up in the way that many South Asian women feel worse, not better, when they adopt Western diet patterns, even nominally healthy ones, because those patterns are foreign to a gut microbiome that evolved around something else entirely.

A study on intergenerational trauma in the context of the 1947 Partition documented that trauma from the partition was measurably transmitted to the next generation, with descendants scoring at medium levels of intergenerational trauma even without direct experience of the events. The body does not distinguish between inherited memory and lived experience. It just carries what it was given.

Why does this matter for how you understand your own health?

When a South Asian woman gets a metabolic diagnosis, the conversation is almost always about what she is doing wrong. Her diet. Her exercise habits. Her stress levels. The conversation is almost never about what her body is doing right, which is surviving, the only way it was built to survive.

The insulin resistance that predisposes her to PMOS and type 2 diabetes is not a defect. It is the metabolic legacy of a physiology shaped by repeated famine and stress. The difficulty losing weight at a "normal" BMI is not weakness. It is a body that was designed to hold onto energy because holding onto energy once meant the difference between living and dying.

This reframe matters not because it removes responsibility for your health but because it removes the shame that comes with not understanding why your body works the way it does. Shame is not a health intervention. Context is. When you understand that your body is doing something ancient and purposeful, you can work with it differently than if you believe it is simply failing you.

It also changes what support looks like. Supplements, diet changes, and lifestyle interventions all work differently when you understand the physiological terrain you are working with. South Asian bodies are not the same as the bodies that most clinical reference ranges were built around. They need approaches that account for their particular history. That is part of what BBR is built to do. The connection between ancestral metabolism and the ingredients in AM Recharge, specifically berberine, chromium, and vitamin D, addressing insulin sensitivity from multiple angles, is not coincidental. We explore the full picture in the posts on insulin resistance supplements and PMOS supplements for South Asian women.

What does this mean practically?

Understanding your ancestral biology is not a reason to be fatalistic. It is a reason to be precise. 

Your gut isn't broken if it doesn't respond well to a Western diet. It was built around something different. Traditional South Asian foods- lentils, whole grains, fermented foods like yogurt and dosas, spiced preparations- are not just cultural. They are probiotic, prebiotic, and anti-inflammatory in ways that the research is only beginning to fully document. If you feel better eating the foods your family ate, that is not nostalgia. That is your gut microbiome telling you something real.

Stress is metabolic, not just psychological. For South Asian women carrying the physiological inheritance of ancestral stress alongside the very real present-day pressure of performing well in environments that were not built for them, the stress load is not ordinary. The nervous system needs consistent, deliberate support. Not as a luxury. As maintenance on a system that is working harder than it should have to.

And the shame that so many South Asian women carry about their bodies, about their weight, their metabolic diagnoses, their inability to "just" eat well and be healthy, belongs to the history, not to them. Your body is not your failure. Your body is your grandmother's survival. It deserves to be treated accordingly.

That is what we are trying to do at BBR. One supplement, one blog post, one conversation at a time.
