Ultra-processed foods linked to increased disease and metabolic risks

New research indicates that ultra-processed foods are linked to significantly higher risks of various chronic diseases and mortality. A large-scale analysis published in Family Medicine and Community Health, which reviewed data from over 8.8 million adults across the Americas, Europe, Asia, and Oceania, found that high consumption of these industrially manufactured products is associated with a 24 per cent increased risk of cardiovascular events, a 23 per cent increase in obesity or overweight, and a 24 per cent increase in metabolic syndrome or diabetes. The study also noted higher risks for cancer, depression, anxiety, and digestive diseases.

Furthering the understanding of why these foods are harmful, a study reported in Nature Metabolism suggests that the processing itself may trigger different metabolic responses, even when calories and nutrients are held constant. Researchers from Virginia Tech conducted an experiment where healthy-weight adults consumed meals that were matched for nutritional composition and energy. Despite the identical caloric and nutrient profiles, the ultra-processed meal produced a different metabolic outcome compared to the minimally processed meal, suggesting that the method of food production impacts how the body processes nutrients.
