Red wine compound seen protecting heart from aging

A natural compound found in red wine may protect the heart against the effects of the aging process, researchers said on Tuesday.

In their study, mice were given a diet supplemented with the compound known as resveratrol starting at their equivalent of middle age until old age.

These mice experienced changes in their gene activity related to aging in a way very similar to mice that were placed on a so-called calorie restriction diet that slows the aging process by greatly cutting dietary energy intake.

Most striking was how the resveratrol, like calorie restriction, blocked the decline in heart function typically associated with aging, according to Tomas Prolla, a University of Wisconsin professor of genetics who helped lead the study.
