The Claim

Higher intake of ultra-processed foods is associated with an increased risk of obesity, cardiovascular disease, type 2 diabetes, and all-cause mortality in adult populations across high-income countries.

In plain English

People who eat more ultra-processed foods have a higher rate of obesity, heart disease, type 2 diabetes, and death from any cause compared to those who eat less.

See the scientific wording

Higher intake of ultra-processed foods is consistently associated with increased risk of obesity, cardiovascular disease, type 2 diabetes, and all-cause mortality in adult populations across high-income countries, based on multiple observational cohort studies with moderate certainty of evidence.

Why this might work

Ultra-processed foods are designed to be eaten quickly and taste intensely sweet, fatty, and salty, which tricks the brain into wanting more and prevents the body from feeling full. This causes people to eat too many calories, leading to fat buildup in the liver and body, while also damaging the gut lining and blood vessels. The liver starts making excess fat, the bloodstream fills with harmful fats, and inflammation spreads throughout the body, causing obesity, diabetes, heart disease, and early death.

  1. Study: Ultra-processed foods and cardiometabolic risk: from evidence to policy

    People who eat more packaged snacks, sugary drinks, and ready-made meals tend to gain weight and get sick more often, and this study shows that clearly — even when the food has the same nutrients, people eat more calories and gain weight on ultra-processed diets.
