Why Indians Fall Ill: Food, Habits and the System

What goes wrong from before birth to adulthood: diet, salt, sugar, inactivity, adulterated food and fake paneer, why the system does not stop it, and what has to change.

Key Points
  • India's own nutrition institute puts 56.4% of India's disease burden down to unhealthy diets, and says up to 80% of type 2 diabetes could be prevented with a healthy diet and exercise[1].
  • It starts before birth. A small, anaemic mother tends to have a baby that is short on muscle but not on fat, a body that is primed for diabetes later[2]. 57% of Indian women of child-bearing age were anaemic in 2019–21[3].
  • Indian adults get 62% of their calories from carbohydrates and only 12% from protein[4], eat about 8 grams of salt a day against a limit of 5[5], and half do too little exercise[6]. The result: 30.7% of women and 27.3% of men are overweight, and one in five has high blood sugar[7].
  • Food is not always what it claims. About 1 in 5 food samples tested by the regulator fails its standards[8], and in 2024–25 so did 12,780 of 33,405 milk and milk product samples[9]. "Paneer" in many restaurants is a cheaper imitation made from vegetable oil and starch, which the law says must be labelled[10][11].
  • What must change: clear warning labels on packaged food, protection for children, more protein and less refined starch, less salt, real enforcement against adulteration, and a record of every person's weight, blood pressure and sugar over the years.

1. Is Food Really the Main Cause?

56.4%Share of India's total disease burden caused by unhealthy dietsICMR-NIN, 2024[1]
up to 80%Share of type 2 diabetes that a healthy diet and physical activity could preventICMR-NIN, 2024[1]

Heart disease and stroke cause about 3 in every 10 deaths in India, diabetes and kidney disease many more (what Indians die of). These diseases are built over decades by what people eat, how much they move, whether they smoke, and how early anyone notices a rising number. None of them arrives on one day.

2. When Does It Start? Before Birth

In a study near Pune, babies born in villages weighed about 2.7 kg against 3.5 kg for babies in Southampton, UK. They were smaller in every measure, most of all in the abdomen and the arm muscles, but their body fat was nearly the same. The researchers called this the "thin-fat" Indian baby: little muscle, preserved fat, and a body that is more likely to resist insulin later in life[2].

57%Women aged 15 to 49 who were anaemic, up from 53.1%NFHS-5, 2019–21[3]
59.1%Teenage girls aged 15 to 19 who were anaemic, the mothers of the next generationNFHS-5[3]
67.1%Children under five who were anaemicNFHS-5[3]

What is wrong: a girl who is undernourished and anaemic becomes a mother who is undernourished and anaemic, and her baby starts life with the body type most at risk of diabetes. The newest survey (NFHS-6, 2023–24) has not yet published national anaemia figures in its first release.

3. What Goes Wrong in Childhood?

Two things at once. Many children still do not get enough food: 29.3% of children under five are too short for their age and 31.8% are underweight[7]. And the food they do get is changing.

13% to 15%Share of children's daily calories that come from sugar (ages 4 to 10, and 11 to 18), against a recommended limit of 5%CBSE, 2025[12]
34%Children aged 5 to 9 with high blood triglycerides, a fat in the blood linked to heart diseaseICMR-NIN, 2024[1]

What is wrong: sweet drinks, biscuits, packaged snacks and sweets have become everyday food for children, while milk, eggs, pulses, fruit and vegetables are too little. The CBSE now asks schools to put up "sugar boards" showing how much sugar common foods contain[12]. A child whose body was built thin-fat before birth and is then fed sugar and refined starch is on the shortest road to diabetes.

4. What Goes Wrong in Adults?

What we doWhat is recommendedWhy it matters
62% of calories from carbohydrates, mostly white rice, wheat and sugar[4]No more than 45% from cereals and millets[1]More carbohydrate calories go with 14% higher odds of newly found diabetes[4]
Only 12% of calories from protein, very little from milk (2%) or eggs, fish and meat (1%)[4]Up to 15% from pulses, beans and meat, plus milk, nuts and vegetables[1]Swapping 5% of calories from carbohydrate to plant or dairy protein went with lower diabetes risk[4]
Saturated fat above the limit in almost every state[4]Below 7% of calories for metabolic health[4]Raises cholesterol and heart disease
About 8 grams of salt a day (men 8.9, women 7.1)[5]Under 5 grams[5]The main dietary cause of high blood pressure, and through it, stroke
49.4% of adults insufficiently active, up from 22.3% in 2000; 57% of women[6]At least 150 minutes of moderate activity a week[13]Muscle is where the body uses sugar; less muscle, more diabetes
Tobacco used by 28.6% of adults in 2016–17, the latest national survey[14]NoneHeart disease, stroke, lung disease and mouth cancer
30.7% · 27.3%Women and men who are overweight or obese, up from 24% and 22.9% five years earlierNFHS-6, 2023–24[7]
17.8% · 20.9%Women and men with high blood sugar or on diabetes treatment, up from 13.5% and 15.6%NFHS-6, 2023–24[7]

A trap specific to Indians: South Asians develop diabetes at a much lower weight. A body mass index of 23.9 in a South Asian carries the same diabetes risk as 30 in a white European[15]. A man who does not look fat can still be at high risk, which is why waist size and blood sugar need to be checked, not just weight.

5. Why Is the Indian Diet Changing?

13.37%Yearly growth in sales of ultra-processed food in India, 2011 to 2021: packaged snacks, sweet drinks, ready mealsWHO and ICRIER[16]
77%Share of concentrates and squashes in packaged drinks in 2021WHO and ICRIER[16]
21States and union territories where people eat more sugar than the national limitICMR-INDIAB[4]

Packaged food is cheap, tasty, heavily advertised and sold in every small shop. Families have less time to cook, more money to spend, and fewer reasons to walk. Nothing on the front of the pack tells the buyer it is high in sugar, salt or fat. WHO and ICRIER asked India to define "high fat, sugar and salt" food clearly and to tax it more heavily[16].

6. Is the Food Even What It Claims to Be?

1 in 5Food samples that failed the regulator's tests in 2024–25: 34,388 of 1,70,535; about 1 in 4 on average since 2014–15FSSAI data[8]
38%Milk and milk product samples that failed in 2024–25: 12,780 of 33,405Lok Sabha reply[9]
107 of 171Cotton candy and gobi manchurian samples in Karnataka with unsafe colours, including Rhodamine-B, a textile dye2024[17]

Of the failed samples, nearly half were sub-standard (poorer quality than the label says), about 15% were unsafe to eat, and the rest were wrongly labelled[8]. The regulator samples what it can; most food sold loose, by street vendors and in small eateries, is never tested.

7. Why Is Fake Paneer Everywhere?

  • 1

    What it is. Real paneer must be made only from milk; Indian food standards do not allow vegetable oil, fat or other protein in it[11]. The imitation, called "analogue paneer" or "cheese analogue", is made from edible vegetable oil, starch and emulsifiers[10].

  • 2

    Why it is used. It is cheaper than milk paneer, looks the same in a curry, and the customer cannot tell. Selling it is legal only if it is clearly labelled as an analogue; selling it as paneer breaks food law[18].

  • 3

    Why it matters for health. It generally has less protein and calcium and more unhealthy fat and carbohydrate than real paneer; if made with hydrogenated oil, it can carry trans fat[11]. For many vegetarian Indians, paneer is one of the few good protein sources, so the swap removes protein from a diet already short of it[4].

  • 4

    What is being done. Maharashtra required restaurants to state "cheese analogue" on menus, bills and boards from May 2026[10]. Zomato removed declared analogue-dairy dishes in September 2026[18]. The national regulator is considering a ban, or sale only in sealed packs with mandatory menu disclosure; at least eight states have their own restrictions[11].

The pattern is bigger than paneer. When a cheaper substitute can pass for the real thing and the chance of being tested is low, someone will substitute. The same logic drives watered or starched milk, coloured spices and dyed snacks.

8. Why Does the System Not Stop This?

  • Labels came late. The food regulator has worked on front-of-pack labels since 2018. A 2022 "health star" draft was dropped. Only after the Supreme Court pressed it did the regulator propose red warning labels ("High Sugar", "High Salt", "High Fat") in 2026, and even these would first apply only to foods high in two or more of them[19].
  • Penalties are small. The maximum penalty critics cite under the Food Safety and Standards Act for such violations is ₹3 lakh[19]. Over ten years, about 2.4 lakh cases were launched and penalties totalled ₹383 crore[8], small against a food market of this size.
  • Too few inspectors and analysts. In June 2026 the regulator asked states to fill vacant food safety officer posts[20].
  • No early warning in health care. Most adults never have their sugar, blood pressure or waist measured until something goes wrong, and when they are, the number is not kept anywhere the next doctor can see.

India has shown it can act: industrial trans fat in oils and fats has been capped at 2% since January 2022[21].

9. What Has to Change

The Government

  • 1

    Warning labels on every high sugar, salt or fat pack, quickly. In Chile, warning labels, limits on advertising to children and a ban on such food in schools cut household purchases of these drinks by about 24% within two years[22].

  • 2

    Tax by sugar, salt and fat, with lower tax on healthier versions, as WHO and ICRIER recommended[16].

  • 3

    Protect children: no junk food in or near schools, no advertising aimed at children, and sugar shown plainly.

  • 4

    Feed girls and mothers well, so that fewer babies are born thin-fat: iron, protein and care from adolescence through pregnancy.

  • 5

    Put more protein, less refined starch, into public food programmes (our view, following the ICMR-INDIAB finding that protein, not a switch of grain, lowers risk[4]).

  • 6

    Enforce food law: fill inspector and laboratory posts, raise penalties, publish the names of products that fail, and make substitutes such as analogue paneer impossible to pass off.

  • 7

    Measure every adult regularly (weight, waist, blood pressure, sugar) at the local health centre, and keep the numbers in the person's record.

Families

  • Fill less of the plate with rice or roti, and more with dal, pulses, curd, milk, eggs, vegetables and fruit[1].
  • Cut salt, sugar and packaged snacks, especially for children; drink water, not sweet drinks.
  • Walk or play every day, and check sugar and blood pressure once a year after 30, even if you feel well.
  • Ask restaurants whether the paneer is real paneer.

Where 1Heath fits. Diabetes and high blood pressure take years to build. They can be seen coming: a weight that creeps up, a fasting sugar of 105 that becomes 118, a blood pressure of 130 that becomes 142. Those numbers are measured at clinic visits and then lost on paper slips. 1Heath keeps them on one record, so the doctor sees the trend, not one reading.
