New research intensifies concerns over health risks of ultra-processed foods

A recent study reveals that increasing consumption of ultra-processed foods significantly raises the risk of heart disease, obesity, and premature death, prompting experts to recommend prioritising whole foods in diets.

A new analysis has added to growing concern about ultra-processed foods, linking higher intake with a greater risk of cardiovascular disease and a range of other health problems. The study, published in Family Medicine and Community Health, found that every extra 100 grams of ultra-processed food consumed a day was associated with a 14 per cent higher risk of cardiovascular events, alongside increased risks of obesity, metabolic syndrome, depression, digestive disease, cancer and premature death.

The findings fit into a wider body of research suggesting that diets heavy in ultra-processed products are associated with poorer heart health. A prospective cohort study published in The BMJ found that greater consumption was tied to a higher risk of cardiovascular disease, coronary heart disease and cerebrovascular disease. Research in the Journal of the American College of Cardiology also linked higher intake of these foods with more cardiovascular illness and greater mortality, reinforcing the view that diet quality matters as much as calorie count.

Ultra-processed foods are typically products made with industrial ingredients and additives, often formulated to be cheap, convenient and highly palatable. Research published in Nutrition Journal found positive associations between these foods and obesity, metabolic syndrome and depression, although the authors said larger prospective studies were still needed to confirm how strong and consistent those links are. Other studies have also raised questions about the health effects of common additives, including sweeteners, emulsifiers, preservatives and flavourings, with researchers noting the possibility of a so-called cocktail effect when multiple additives are consumed together.

Indian health experts quoted by Indian Express said the concern is not that an occasional packaged snack will cause harm, but that these products can steadily displace more nutritious foods when they become a regular part of the diet. Fauziya Ansari, a dietitian at Apollo Spectra Hospital Mumbai, said frequent intake can increase consumption of salt, sugar, unhealthy fats and excess calories, all of which may contribute to weight gain, high blood pressure, diabetes and abnormal cholesterol. Parin Sangoi, a consultant interventional cardiologist at Wockhardt Hospitals in Mumbai, said the evidence on additives is still emerging and should be interpreted carefully, but added that the safest approach is to make whole or minimally processed foods the basis of everyday meals.

That advice is consistent with broader cardiovascular research. A population-based cohort study in The BMJ found that higher ultra-processed food intake was associated with a greater risk of death from all causes, including cancer and cardiovascular disease, while research in the International Journal of Behavioral Nutrition and Physical Activity linked these foods to cardiovascular mortality in the United States. For people with hypertension, diabetes, high cholesterol or existing heart disease, experts say the practical message is to reduce reliance on ready-to-eat products and build meals around vegetables, fruit, pulses, whole grains, nuts and seeds.
