Ultra-processed food consumption linked to increased chronic disease risk

A large-scale analysis of 51 studies involving nearly 9 million adults has linked high consumption of ultra-processed foods (UPFs) to an increased risk of several chronic conditions. Researchers found that high UPF intake is associated with a 31% higher risk of digestive diseases, a 27% higher risk of depression or anxiety, and a 24% higher risk of cardiovascular events and diabetes. Additionally, the highest intake group showed an 18% higher risk of death from any cause and a 12% higher risk of cancer.

In a separate study conducted as part of the NutriNet-Santé project in France, researchers tracked over 112,000 volunteers to investigate the impact of food preservatives. The study suggests that common additives used to prevent spoilage and maintain color may be linked to higher risks of high blood pressure and cardiovascular disease.

Globally, the consumption of UPFs—which include packaged snacks, sugary drinks, and ready-to-eat meals—has risen steadily. In the United States and the United Kingdom, these foods now account for approximately half of adult caloric intake.
