A growing body of evidence shows that ultra-processed foods are displacing traditional, whole-food diets worldwide and driving major diet-related chronic diseases. Drawing on decades of dietary surveys, global sales data, cohort studies, randomized trials, and mechanistic research, this first paper in a three-part Lancet Series reports that ultra-processed foods have rapidly replaced long-established eating patterns; that this shift worsens diet quality through overeating, nutrient imbalance, loss of protective compounds, and increased exposure to harmful additives; and that it raises the risk of a wide range of chronic diseases affecting nearly every organ system. Together, more than 100 prospective and interventional studies support the conclusion that this dietary shift is a key contributor to the global rise in chronic illness, with companion papers outlining policy and public health strategies to restore diets based on fresh and minimally processed foods.
