Good news for red wine amateurs, especially we Zoroastrians!
Resveratrol, a compound found in grapes, red wine, pomegranates and certain other foods, may protect the heart and slow the effects of aging, a new study suggests.
Tests in mice revealed that low doses of resveratrol mimic the effects of caloric restriction, diets with 20% to 30% fewer calories than a typical diet that have been shown to extend life span.
Previous research has shown that high doses of resveratrol prevent early death in mice fed a high-fat diet. This new study adds to those findings, showing that receiving low doses of resveratrol in middle age offers many of the benefits as a calorie-reduced diet.
«This brings down the dose of resveratrol toward the consumption reality mode. At the same time, it plugs into the biology of caloric restriction», co-senior author Richard Weindruch, a professor of medicine at the University of Wisconsin-Madison, said in a prepared statement.
The researchers found that resveratrol affected age-related gene expression changes in the heart tissue of mice. The study was published online this week in the Public Library of Science One.
