The Two Faces of Malnutrition
India is currently experiencing what public health experts call the “double burden of malnutrition.” This means that two opposite problems are occurring at the same time: a significant part of the population is undernourished, while another large segment
is overweight or obese. The latest National Family Health Survey (NFHS-6) highlights this stark reality. Even as the share of adults who are overweight or obese has risen sharply, the proportion of those with a below-normal Body Mass Index (BMI) has also slightly increased, shrinking the number of people in the healthy weight range. This isn't just a national statistic; the double burden can exist within the same community and even the same household, where a child might be underweight while an adult is overweight.
The Old Foe: Undernutrition Lingers
Despite economic progress, undernutrition remains a stubborn challenge. Stunting (being too short for one's age) and wasting (being too thin for one's height) still affect a large number of children. According to NFHS-6 data, nearly one in three children under five is still stunted. While there have been improvements, with stunting declining from 35.5% to 29.3% between the last two surveys, the numbers are still high. These conditions have long-term consequences, affecting a child's chances of survival, ability to learn, and future productivity. The data shows that while many government initiatives exist, achieving adequate nutrition for every child, especially in the first 1000 days of life, remains a critical and unfinished task.
The New Threat: A Surge in Lifestyle Diseases
At the other end of the spectrum is a rapidly escalating crisis of overnutrition. The prevalence of overweight and obese adults has climbed steeply. This shift is directly linked to an increase in non-communicable diseases (NCDs) like diabetes, hypertension, and cardiovascular disease, which now account for over 60% of all deaths in India. Studies show that diabetes prevalence has reached 11.4%, affecting 101 million people, with another 136 million in the pre-diabetic stage. This health shift is driven by what experts call the "nutrition transition," where traditional, minimally-processed diets are replaced by energy-dense, convenience-oriented foods.
The Role of the Modern Diet
A primary driver of this transition is the explosive growth of the ultra-processed food (UPF) market in India, which grew at a compound annual rate of over 13% between 2011 and 2021. These industrial formulations—high in sugar, salt, and unhealthy fats but low in essential nutrients—are becoming increasingly common. Items like packaged snacks, sugary drinks, and fast food are not just urban indulgences anymore; they are penetrating rural markets and becoming staples across all socioeconomic segments. Research has established a direct link between a higher share of UPFs in the diet and an increased risk of obesity, diabetes, and hypertension. An average Indian household now gets more calories from processed foods than from fruits.
Changing Lifestyles and Urban Shifts
The dietary changes are compounded by significant shifts in lifestyle. Rapid urbanization has led to more sedentary jobs, longer commutes, and less physical activity. The convenience of grocery delivery apps, for instance, reduces even basic physical activity like walking to a shop. This lack of movement, combined with a high-calorie diet, creates a perfect storm for weight gain and metabolic diseases. The problem is no longer confined to older adults; doctors are seeing conditions like high blood pressure and prediabetes in people in their twenties and thirties.
What Can Be Done?
Tackling this double burden requires a two-pronged approach that addresses both undernutrition and overnutrition simultaneously. Experts call for "double-duty actions"—policies that can solve both problems. This includes strengthening programs that ensure maternal and child nutrition, like POSHAN Abhiyaan and the Integrated Child Development Services (ICDS). At the same time, there is an urgent need for policies that promote healthier food environments. This could involve clearer front-of-package labelling on processed foods, taxes on sugary drinks, restrictions on junk food marketing to children, and public health campaigns that encourage balanced diets and physical activity. The goal must shift from mere food security (enough calories) to nutrition security (the right nutrients).
