Ultra-processed foods threaten brain health in kids and teens, review warns

Children, adolescents, and unborn babies exposed to high levels of ultra-processed foods (UPFs) face increased risks of impaired brain development, cognitive deficits, and long-term mental health challenges. The review underscores how UPF-driven changes in reward pathways, nutrient deficits, inflammation, and the gut–brain axis can have lasting impacts across generations.
