A University of Southern California (USC) study has found that adolescents who eat a lot of junk food could end up having impaired long-term memory when they grow older.
The study, published in the peer-reviewed journal Brain Behavior and Immunity, was conducted among rats fed a diet full of fat and sugar during adolescence. The study also builds on prior research linking poor diet to Alzheimer’s disease, a condition characterized by reduced levels of the neurotransmitter acetylcholine in the brain. Acetylcholine is crucial for memory, learning, attention and other cognitive functions.
