Summary

Story summary

A Chiba University study shows high-fat diets (HFDs) impair memory in fruit flies by disrupting autophagy, the brain's recycling system.
Flies on HFDs retained immediate recall but lost intermediate and long-term memory after one week.
Autophagy failure caused cellular junk buildup in memory circuits.
Drugs like rapamycin restored memory function, suggesting reversibility of cognitive decline.
The study highlights diet's role in brain health and potential interventions for neurodegenerative diseases.
