What's in Red Wine that are good for heart?

Red wine is a particularly rich source of antioxidants flavonoid phenolics, so many studies to uncover a cause for red wine's effects have focused on its phenolic constituents, particularly resveratrol and the flavonoids. Resveratrol, found in grape skins and seeds, increases HDL cholesterol and prevent blood clotting. Flavonoids, on the other hand, exhibit antioxidant properties helping prevent blood clots and plaques formation in arteries.

Should I start drinking more red wine now?

The answer is No. Studies showed that alcohol drinking may increase triglycerides (another Bad blood lipids) and result in weight gain due to its empty calories. Other studies also suggested that alcohol consumption is associated with cancer risk. Read Alcohol and Cancer. The American Heart Association cautions people NOT to start drinking if they do not already drink alcohol. If you already drink alcohol, do so in moderation. AHA recommends one to two drinks per day for men and one drink per day for women. (A drink is one 12 oz. beer, 4 oz. of wine, 1.5 oz. of 80-proof spirits, or 1 oz. of 100-proof spirits.)
