Experts highlight limits of evidence from ultraprocessed food trials

Article excerpt

European researchers publishing in Science have raised concerns about the strength of evidence linking ultraprocessed foods to poor health outcomes. The experts highlight methodological limits in existing trials, many rely on self-reported dietary data, lack long-term follow-up, and struggle to isolate UPF effects from overall diet quality. While acknowledging potential harms, the group argues that current science doesn't definitively prove ultraprocessed foods themselves cause disease independent of caloric excess and nutritional imbalance. The critique doesn't deny health risks but calls for more rigorous experimental design before making sweeping public health claims.
