Summary

Story summary

A study in Physiology & Behavior found that caffeine did not protect against memory impairment from a high-fat, high-sugar diet, in two experiments with 1,699 healthy volunteers.
The first experiment showed a weak moderating effect of caffeine on self-reported memory.
The second experiment confirmed that caffeine did not mitigate memory impairment.
Researchers noted limitations and urged future studies to use objective tracking and explore different populations and cognitive functions.
