MIAMI – NOVEMBER 01: Bottles of red wine are seen on the shelf at Old Vines Wine & Spirits on November 1, 2006 in Miami, Florida. A study by the Harvard Medical School and the National Institute on Aging showed that obese mice benifited from consuming huge doses of the red wine extract, resveratrol, and had a healthy effect on the fat-related ill effects. Resveratrol is found in the skin of grapes used to make red wine. (Photo by Joe Raedle/Getty Images)
