Consumer Health: Grape juice, red wine and heart health
Share this:
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 coronary artery disease, the condition that leads to heart attacks.
The American Heart Association and National Heart, Lung, and Blood Institute don't recommend that you start drinking alcohol just to prevent heart disease, though. Alcohol can be addictive. And excessive drinking can lead to high blood pressure, and increase your risk of heart failure or stroke. Even a single binge can cause a serious heart arrhythmia called atrial fibrillation.
Some research studies suggest that red and purple grape juices may provide some of the same heart-healthy benefits of red wine. Grapes are rich in health-protecting antioxidants, including resveratrol and flavonoids.
Learn more about the heart-healthy benefits of grapes and grape juice from Katherine Zeratsky, a Mayo Clinic registered dietitian nutritionist.
