The impact of ultra-processed foods on pediatric health

Ultra-processed foods (UPFs) have become increasingly incorporated into pediatric diets, accounting for approximately 67 % of the total energy consumption in United States (US) children. Manufactured through industrial processing and enriched with excess sugars, unhealthy fats, and sodium, while lacking essential nutrients, UPFs present a substantial public health concern. We aimed to conduct a comprehensive review of the impact of UPFs on pediatric health.

We reviewed the effects of UPF on pediatric health using data from observational studies, systematic reviews, and policy reports. Our review explored the social, environmental, and economic drivers of UPF consumption, associated health consequences, and proposed mitigation strategies. We also examined National Health and Nutrition Examination Survey (NHANES) data, the 2025 US Dietary Guidelines Advisory Committee's (USDA) report, and the Make America Healthy Again (MAHA) commission findings.

UPF intake has dramatically increased during early childhood, with toddlers and school-aged children obtaining 47 % and 59.4 % of their daily calories, respectively, from UPFs. Higher consumption is linked to pediatric obesity, cardiometabolic risks such as insulin resistance and metabolic dysfunction-associated steatotic liver disease (MASLD), mental health concerns, and gut microbiome disruption. Early-life exposure to UPFs can establish unhealthy dietary patterns that persist into adulthood, raising the risk of chronic disease. Greater UPF consumption is often observed among lower-income families, highlighting a key health disparity.

UPF consumption is a modifiable risk factor for non-communicable diseases in children. Addressing it requires urgent, coordinated action at multiple levels. Strategies include UPF and sugar-sweetened beverage screening during well-child visits, policy restrictions on food marketing, clearer nutrition labeling, healthier school meals, and personalized family-centered dietary counseling. Clinicians need standardized tools and training to counsel families effectively. Policy initiatives should prioritize prevention-focused measures to protect children's health.
