Study: Sip of wine ups math test scores

April 1, 2009 British researchers say small amounts of resveratrol, which is an active ingredient in red wine, raised people's performance on mental math tests.

Resveratrol works by increasing blood flow to the brain. It has also been associated with reducing the risk of heart disease.

Other studies have linked resveratrol with fighting cancer, obesity and diabetes among other diseases.

In addition to red wine, resveratrol can be found in raspberries, blueberries, and cranberries.
