A new study from Germany reports that regular increased intakes of the polyphenol resveratrol seem to support memory performance and glucose metabolism in older adults.
In the randomized controlled trial, 46 participants aged between 50 and 75 years performed memory tests before and after they received either 200 mg resveratrol per day of or a placebo for 26 weeks (1). The study results showed that participants who were supplemented with resveratrol had significant improvements in the retention of words over 30 minutes compared with placebo. In addition, neuroimaging data showed that resveratrol led to a significantly increased functional connectivity of the hippocampus. Moreover, resveratrol supplementation was associated with decreased levels of glycated hemoglobin (HbA1c) – a marker of long-term presence of excess glucose in the blood.
The researchers commented that increased resveratrol intakes may be a new strategy to maintain brain health during aging. While earlier research has linked resveratrol intakes to improved blood flow in the brain (2), the new results indicate that the polyphenol may be able to modulate brain function. Resveratrol, found in grapes and red wine has been intensively investigated for potential cardiovascular benefits.

The current focus of nutritional science has shifted from meeting needs to determining the biological effects that nutrition has on immediate and lifetime health.

Observations from epidemiological studies on the protective effect of antioxidant micronutrients in relation to cardiovascular diseases (see Part 1) warranted an attempt to prove the hypothesis by means of intervention studies. However, the results of many randomized controlled studies were disappointing: many investigations revealed few, if any, differences between groups receiving placebo and those receiving food supplements with vitamin C and/or E and beta-carotene in regard to the risk of developing cardiovascular disease, a benefit was found in only a few groups.
