Summary

Story summary

A Chiba University study indicates that high-fat diets impair memory in fruit flies within a week.
While short-term memory remains intact, intermediate-term memory declines significantly due to a malfunctioning cellular cleanup system, autophagy.
Enhancing autophagy restored memory function, suggesting potential reversibility of cognitive decline.
The findings emphasize the need for balanced diets for brain health and link high-fat diets to cognitive decline in humans.
Further research is necessary to explore human applications.
