The Rise of Ultra-Processed Foods

Ultra-processed foods (UPF) have become increasingly popular and pervasive in our diets, comprising about 60% of total calories consumed in the US. UPF is a category that includes highly processed and artificial ingredients, which are often low in nutrition and high in additives. The Nova classification system categorizes foods into unprocessed/minimally processed, processed culinary ingredients, processed foods, and ultra-processed foods. UPF has been associated with an increased risk of various diseases, including cancer and cardiometabolic diseases. Animal-based products and artificially sweetened beverages were found to be particularly detrimental, while plant-based alternatives showed no significant association with increased risk.
