Red wine and resveratrol: Good for your heart?
Red wine and something in red wine called resveratrol might be heart healthy. Find out the facts, and hype, regarding red wine and its impact on your heart.

Red wine, in moderation, has long been thought of as heart healthy. The alcohol and certain substances in red wine called antioxidants may help prevent heart disease by increasing levels of "good" cholesterol and protecting against artery damage.

While the news about red wine might sound great if you enjoy a glass of red wine with your evening meal, doctors are wary of encouraging anyone to start drinking alcohol. That's because too much alcohol can have many harmful effects on your body.

Still, doctors do agree that something in red wine appears to help your heart, though it's unclear just exactly what that "something" is. Researchers think antioxidants, such as flavonoids or a substance called resveratrol, have promising heart-healthy benefits.

Resveratrol in red wine
Resveratrol might be a key ingredient in red wine that helps prevent damage to blood vessels, reduces "bad" cholesterol and prevents blood clots.

Resveratrol in grapes and other foods
The resveratrol in red wine comes from the skin of grapes used to make wine. Because red wine is fermented with grape skins longer than is white wine, red wine contains more resveratrol. Simply eating grapes, or drinking grape juice, has been suggested as one way to get resveratrol without drinking alcohol. Some studies have suggested that red and purple grape juices have some of the same heart-healthy benefits of red wine.
