India's Diabetes Epidemic: Diet and Income

Economic development in India has done more than raise income levels. It has radically altered consumer behavior, nutrition and lifestyle patterns. Pre-packed snacks, beverages, instant foods, and processed products are becoming increasingly available, especially in urban centers. Convenience foods compete against home cooking, while inactive lifestyles are curtailing physical activity.

This transformation has yielded many advantages, but it has also come at a considerable public health price. The prevalence of diabetes in India stems from the interplay of factors such as changing nutrition patterns, genetic disposition, obesity, inactivity and unequal access to preventive health care services. The problem is no longer one of adequate nutrition; it has become one of nutrition quality.

The Changing Economics of India’s Food Choices

With an increase in disposable income, more options are available to consumers. Restaurant consumption, ready-to-eat packaged foods, food deliveries, and products which can solve the problems associated with their busy lifestyle are some examples. Processed foods are easily available at supermarkets and even through the internet.

But just because of increased purchasing power does not mean consumers will be able to choose healthier foods. Ultra-processed foods tend to be aggressively marketed and widely available. Foods rich in added sugar, salts, and fats tend to substitute healthier food options.

The 2023 World Health Organization‘s report about ultra-processed foods in India has discussed the fast-growing market and the requirement for policies that allow healthy food options to become more affordable. India’s Economic Survey 2025-26 also noted the fast-growing retail sales of ultra-processed foods along with obesity rates.

This issue needs to be studied because, apart from individual choice, factors like affordability, marketing, availability, and work environment influence food choices.

Diabetes Is Becoming a National Health Challenge

The magnitude of the diabetes epidemic in India is frightening. According to the ICMR-INDIAB survey in 2023 reported in the journal The Lancet Diabetes & Endocrinology, there are about 101 million diabetics in India, along with another 136 million prediabetics.

Such numbers indicate the large number of people exposed to metabolic complications in the future. Diabetes may lead to heart disease, kidney complications, nerve damage, and blindness. Financial strain would come from the repeated need for medications, testing, and hospitalization.

According to a research published in Nature Medicine in September 2025, the Indian diet pattern raises concern. The results of the ICMR-INDIAB survey on dietary intake indicate high consumption of low-quality carbohydrates, such as refined grains and added sugar, and lower consumption of protein. Increased carbohydrate intake was associated with a greater risk of type 2 diabetes.

This data proves that switching from one refined grain to another does not necessarily mean improving nutrition.

Why Ultra-Processed Diets Deserve Greater Scrutiny

Not all foods that are packaged fall into this category. The definition is normally taken to refer to industrially formulated products that contain ingredients which are seldom used in normal household cooking.

Their regular consumption may promote excessive energy consumption, leading to displacement of nutrient-packed foods such as pulses, fruits, and vegetables.

But diabetes cannot be attributed to one food group. Genetic factors, age, lack of proper sleep, stress, physical inactivity and other health issues play a role. Additionally, India has a unique problem where people suffer from metabolic diseases despite having low body weight.

This shows that the food environment has to be considered in such public health messages.

Prevention Must Begin Beyond the Doctor’s Clinic

There is need to develop a strong prevention strategy that will make the choice of being healthy an affordable one. The nutrition content of food sold should be made clear to people by means of labels indicating sugar, salt and fat content. It is possible to prohibit unhealthy snacks in schools and offer balanced diets in school canteens.

It is also important to reinforce public awareness of the Indian Council of Medical Research (ICMR)-National Institute of Nutrition’s Dietary Guidelines for Indians which call for diverse diet, balanced meals, and reduced intake of high fat, sugar and salt foods.

Employers can contribute to the cause by making healthy meal choices easily available for their employees, allowing walking breaks, and conducting preventive screening. There is need for primary healthcare centers to screen more people for diabetes, especially those at risk for the disease, and follow-up on those with pre-diabetes.

The food industry too has to play its part.

Economic Growth Must Deliver Better Health

Indicators of success in India cannot only include consumption and food market expansion. The success needs to account for improvements in nutrition, healthy life expectancy, and access to preventive healthcare services.

Prosperity in the country must mean that the economy allows the family to afford healthier food choices, rather than just more convenient ones. Combating diabetes in India is going to require collaboration on the part of policymakers, food producers, healthcare professionals, schools, and consumers.

The true measure of prosperity is not the amount of food consumed by the family, but the impact the food has on their health. India must make sure its prosperity comes without compromising the metabolic health of its people.
