Canada study links ultra‑processed foods to up to one‑third of heart deaths

Researchers analyzing Canadian health data presented at the International Congress on Obesity 2026 estimated that 23 %–38 % of cardiovascular events in 2019 were attributable to consumption of ultra‑processed foods. This corresponds to 58 000–96 000 new cases of coronary disease or stroke and 10 000–17 000 related deaths in that year.

The statistical model compared the actual intake—ultra‑processed foods provided about 43 % of daily energy for adults—to alternative scenarios. Halving consumption was projected to prevent 27 000–46 000 cardiovascular cases and 5 000–8 000 deaths, as well as tens of thousands of years of healthy life lost.

The findings, published in the American Journal of Preventive Medicine, suggest the pattern could apply to other high‑income nations where similar diets prevail. Experts call for public‑health measures to reduce intake of items such as chips, sugary drinks, instant meals and other convenience products that are inexpensive, widely marketed and high in salt, sugar, unhealthy fats and additives. Indian cardiologists note a rising, though still modest, share of such foods in India and warn that increasing consumption could become a larger public‑health concern.
