Are Ultra-Processed Foods a Public Health Hazard? The scientific evidence increasingly suggests yes — ultra-processed foods (UPFs) are considered a significant public health concern, though some nuances and caveats remain. The Scale of the Problem UPFs now dominate diets in many countries. Such food now accounts for nearly 60% of U.S. adults' calorie consumption, and among American children,
