Benefits of Red-Wine

High-fiber Tempranillo red grapes—which are used to make certain red wines, like Rioja—may actually have a significant effect on cholesterol levels, according to a study from the Universidad Complutense de Madrid in Spain.

    Healthy study participants, who consumed the same grape supplement found in red wine saw their LDL, or "bad cholesterol," levels decrease by 9% among healthy. Participants with high cholesterol experienced a drop of 12%. What's the big deal? Excess LDL ends up getting deposited in arterial walls and forming plaque, which causes arteries to stiffen and blood pressure to rise, ultimately leading to heart attacks, says Arthur Agatson, MD, an associate professor of medicine at the University of Miami and author of The South Beach Heart Program.

2. Protect your heartOn top of lowering bad cholesterol, polyphenols—the antioxidants in red wine—can help keep blood vessels flexible and reduce the risk of unwanted clotting, says John Folts, PhD, a professor of cardiovascular medicine and nutrition at the University of Wisconsin–Madison.

   "They're nearly as effective as aspirin," says Folts. But be careful: Chronic heavy drinking damages the heart, so, as with most things, moderation is key. (If you prefer an aspirin to protect your ticker, be sure to covered with

4. Fight off a coldIf you hate getting sick (and who doesn't?), the antioxidants in red wine may help keep you healthy. A 2010 study in the American Journal of Epidemiology found that among 4,000 faculty members at five Spanish universities, those who drank more than 14 weekly glasses of wine for a year were 40% less likely to come down with a common cold. Why? According to the National Institutes of Health, antioxidants are believed to fight infection and protect cells against the effects of free radicals, which may play role in cancer and other diseases.

5. Stop cancerAccording to researchers at the University of Virginia, the resveratrol you get from drinking one glass of red wine three or four times a week may be enough to starve any nascent cancer cells. The scientists dosed human cancer cells with resveratrol and found that the compound inhibited the key action of a cancer-feeding protein.

Clearly, resveratrol is a bit of a limelight hog when it comes to the healthful compounds in vino. But research in the Journal of Biological Chemistry suggests piceatannol, the chemical compound our bodies convert from resveratrol, deserves some credit. This compound was shown to actually prevent the growth of fat cells in a series of lab tests. How? Researchers say that piceatannol binds to the insulin receptors of fat cells, essentially blocking the pathways necessary for immature fat cells to mature and grow.
