The Collapse of the Food Matrix: How Ultra-Processed Foods Impact Satiety and Metabolism by Altering Physical Structure Beyond Nutrient Composition
A 2026 Frontiers in Nutrition review argues that the health risks of ultra‑processed foods (UPFs) stem primarily from the industrial collapse of their physical food matrix, not just poor nutrient profiles. The authors detail how a softened matrix accelerates oral processing, blunts gut hormone release, and creates a rapid nutrient flood that overloads metabolic organs. This cascade triggers insulin resistance, hepatic lipogenesis, gut dysbiosis, and chronic low‑grade inflammation. The paper calls for a paradigm shift in nutrition science and public‑health policy to evaluate food structure alongside composition.
