Eating ultra processed food could cause changes to the brain which could drive overeating

Link Between Ultra Processed Food and Brain Changes

A major new study has found a link between eating ultra-processed food (UPFs) and structural changes to the brain, which could result in 'uncontrolled eating'.

Researchers say their findings demonstrate that "UPF consumption may perpetuate itself" due to differences in the brain linked to diets high in UPFs.

Our findings suggest that higher consumption of ultra-processed foods is associated with differences in the brain.

The international team examined brain scans from 30,000 people, with the study's shared first author, Arsène Kanyamibwa from the University of Helsinki, noting that these associations could be linked to behavioural patterns such as overeating.

Author's summary: Ultra-processed food may cause brain changes leading to overeating.
