"If only preventing a heart attack were as easy as sipping on a nice pinot noir. Well, it may be.According to much enjoyed research, red wine -- in moderation -- is thought to prevent heart disease, which in turn, could prevent heart attacks. One study, conducted by researchers from the Israel Institute of Technology found that blood flow to the heart was improved when participants drank at least one glass of red wine a day for three weeks. This is because cell death, known as apoptosis, was reduced and antioxidants in the wine may help protect the lining of blood vessels in the heart.Another study, done by researchers at the University of Ulm in Germany, found that resveratrol, a substance in red wine, may reduce risk of cardiovascular disease in moderate drinkers. Seems that resveratrol increases levels of ""good"" heart-protecting HDL cholesterol and protects against artery damage. Resveratrol is also thought to prevent blood clots, which are a main cause of heart attacks.To gain the benefits, the researchers recommend that men average about 10 ounces of wine a day and women, about 5 ounces. Remember though, neither the American Heart Association nor the National Heart, Lung, and Blood Institute recommend that you START drinking alcohol to prevent a heart attack. Alcohol can be addictive, and contribute to a wide range of health problems, including high blood pressure, cardiomyopathy, liver damage, obesity and various cancers If you'd rather not indulge in a glass of wine, you can opt for a glass of grape juice, since resveratrol is found in the grape's skin, or for adding peanuts, blueberries and cranberries into your diet, all of which contain resveratrol,If you are on medication or have chronic health issues, talk with your doctor about the potential risks and benefits of drinking wine.
