Experts Warn Ultraprocessed Foods Pose a Major Global Health Threat

Big Food now supplies over half of U.S. adults' at-home calories through ultraprocessed foods and, according to a study in The Lancet, these foods are now a major global health threat driving chronic disease

The NOVA food classification groups foods by processing. Group 4 (ultraprocessed products) are industrial formulations that displace healthy diets and seriously harm health

Across 104 studies, higher ultraprocessed food intake was consistently linked to poorer metabolic health, faster weight gain, diabetes, cardiovascular disease, cancer, and long-term exposure to harmful additives and endocrine-disrupting chemicals

Most governments rely on weak, nutrient-focused policies and voluntary programs, while industry interference and trade challenges block stronger rules that reduce availability, marketing, and additives in ultraprocessed foods

Transnational food giants shape laws, research, and public opinion to protect profits, so personal control starts with awareness, cleaning your pantry, smarter swaps, limiting vegetable oils, and strong social support
