India carries one of the heaviest health burdens in the world. This burden is not new or random. It is rooted in our history, geography, and culture, and it is also shaped by rapid urbanisation, changing diets, and less physical activity.
Salt has always played a part in this story. For centuries, tribal groups who settled inland, such as in Chhattisgarh, lived with little access to salt. Their bodies adapted to that scarcity. Today, in a salt-rich world, that history makes them especially vulnerable to hypertension. In West Bengal, the memory of famine is still written into people’s bodies.
Families that lived through repeated famines passed on to the next generations changes in how food is processed. With famine gone, many now produce too little insulin. The result is diabetes without the usual rise in blood pressure.
Other burdens are also tied to place and history. Oral cancers reflect the mix of ancient betel and areca nut chewing with the current day, daily use of tobacco. Gallbladder cancers in the Gangetic belt come from Himalayan arsenic in the water, and the repeated infections from slow-moving rivers and stagnant pools. In the Northeast, nasopharyngeal cancers are linked to fermented foods, smoke from cooking fuels, and viral exposure. In cities, smaller families, delayed childbirth, and sedentary lifestyles are driving breast and prostate cancers, diabetes, and hypertension at a speed India has never seen before.
This mix of old and new gives India a rare moment in history. Most Indians are still lean and do not suffer from obesity, a much harder problem to reverse. In states like Rajasthan, people remain active, eat whole grains, and use little fat. Many of these diseases have not yet taken hold there. This gives us a chance to act early and “get it right” before patterns become fixed.

Global frameworks like the WHO’s building blocks and the “control knobs” model provide essential tools. They cover financing, governance, medicines, and service redesign. India needs all of these.
But when the roots of disease lie in history, culture, ecology, and new urban risks, we must also draw on the full set of levers of precision public health: service redesign, financial protection, public health capacity, interactions with plants and animals, social policies, and cultural change.
Service redesign is one lever. In coastal Odisha, for example, maternal and child health have improved, but hypertension and diabetes are rising. Here, stronger primary care and better urban design (such as sidewalks seamlessly connected to public transportation and better spacing between high rise buildings) are needed. In the state’s tribal districts, very low C-section rates and high stunting remain. Their needs are hospitals, surgical theatres, and emergency care. In West Bengal, where diabetes often appears without high blood pressure, more sensitive diagnostic strategies and earlier use of insulin are essential.
Hospitals and financial protection are also vital. Cancer patterns show why. Bihar and Uttar Pradesh need specialised care for gallbladder cancer. Gujarat and Maharashtra need oral cancer programmes tailored to local culture. Mizoram and Nagaland need clean-fuel schemes and targeted checks. Delhi and Mumbai need breast and prostate cancer programmes that reflect lifestyle change, pollution, and fertility shifts.

Other changes will take longer but are just as important. Habits like tobacco chewing, salt-rich meals, or fermented diets are deeply tied to identity. They will only shift when new practices become part of everyday life — through school meals, women’s groups, and local leaders.
In West Bengal, fasting traditions among women and high rates of teenage pregnancy add to nutritional shortfalls. These cultural patterns, too, must be revisited. In Kerala and Tamil Nadu, the culture of movement needs to be reintroduced.

India has the chance to act with precision. That means matching responses to burdens, using every lever, and combining quick fixes with deeper change. The way forward is not more of everything everywhere, nor choosing one approach over another. It is precision — aligning design with disease, and disease with history, geography, and culture.
