Red wine has been known to be "heart healthy" for some time now. But newer studies on resveratrol show that this substance found in red wine can also increase memory performance. And as we as a society increase in age, anything that will help memory is welcome.
Abundant in polyphenols, resveratrol has been shown by a number of previous studies to increase memory performance among animal models.
But this study was in humans. Both prior to and following the intervention/control period, subjects underwent memory tasks and neuroimaging to assess volume, microstructure, and functional connectivity of the hippocampus, a key region implicated in memory functions.
In addition, the researchers measured anthropometry, glucose and lipid metabolism, inflammation, neurotrophic factors, and vascular parameters. The team observed a significant effect of resveratrol on retention of words over 30 minutes among the group receiving the resveratrol supplement, as compared to placebo. Further, the resveratrol supplementation led to significant increases in hippocampal functional connectivity, decreases in glycated hemoglobin (HbA1c) and body fat, and increases in leptin.
“This study provides initial evidence that supplementary resveratrol improves memory performance in association with improved glucose metabolism and increased hippocampal [functional connectivity] in older adults."
