Red wines contain antioxidants that can help to increase your ‘good’ cholesterol (HDL) and protect against artery damage by the ‘bad’ cholesterol (LDL). Red wines also contain a substance called resverastrol which help to prevent blood clots, reduce the risk of heart attack and stroke. According to the American Heart Association, the recommended intake is 2 drinks per day for men and 1 drink per day for women (1 drink = 4 ounce/118ml of red wine). Taken in moderation, a glass of red wine help provide many health benefits towards a healthy heart.
