This position paper summarizes associations between high ultra-processed-food consumption and metabolic and chronic diseases, including cancer, and discusses proposed biological, behavioral, and public-health mechanisms, particularly relevant to overconsumption in children and adolescents.
Research significance
The supplied record supports ultra-processed-food exposure as a potentially modifiable risk factor for metabolic dysfunction; it is an inference, not demonstrated pediatric-oncology evidence, that reducing exposure could improve cancer prevention, treatment tolerance, or outcomes in children with cancer.

PURPOSE OF REVIEW: This position paper by the Italian Association of Dietetics and Clinical Nutrition (ADI) evaluates the impact of ultra-processed foods (UPFs) on metabolic health and chronic disease risk, with particular attention to the biological and behavioural mechanisms involved. RECENT FINDINGS: High UPFs consumption has been associated with obesity, insulin resistance, cardiovascular disease, metabolic dysfunction-associated steatotic liver disease (MASLD), cancer, neuroinflammation, and immune dysregulation. Proposed mechanisms include gut microbiota alterations, increased intestinal permeability, mitochondrial dysfunction, oxidative stress, impaired metabolic flexibility, and chronic low-grade inflammation. The hyperpalatable nature of UPFs may also impair appetite regulation and promote overconsumption, especially among children and adolescents. Additional concerns involve food additives, processing-derived contaminants, and endocrine disruptors from packaging materials. Current evidence identifies UPFs as a major modifiable risk factor for non-communicable chronic diseases. Reducing UPFs exposure should therefore represent a public health priority, supported by preventive nutritional strategies, improved food classification systems, and targeted educational and regulatory interventions.
