First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Stanford study looks at how ultra-processed foods (like sugary drinks and snacks) affect brain areas involved in reward, attention, and memory in 162 teenagers aged 13-15. Participants will have brain scans while tasting and viewing different foods, and will also eat from a buffet to measure intake. The goal is to understand why these foods are so compelling and whether individual differences in brain responses play a role.
