Health Benefits of Red Wine

A glass of red wine does more than complement your dinner, researchers are looking into its mix of antioxidants for evidence that they protect your heart and may reduce your risk of cancer1.

Red wine contains over 500 polyphenolic compounds, which are responsible for wine’s color and bitter taste. Resveratrol, a polyphenolic antioxidant, has received the most attention out of all the compounds in red wine.

Resveratrol is found in the skin of red grapes, so more resveratrol makes it into red wines. Resveratrol researchhas shown it may have protective effects against heart disease and many cancers.

Numerous studies have looked into clinical uses for resveratrol, which in trials has shown an ability to inhibit the growth of cancer cells2.

Moderation is the Key

Five ounces of red wine a day, which is a little over ½ cup, has been shown to protect against heart attack in long-term, prospective diet studies. Moderate drinking is defined as no more than two five- ounce wine servings for men and one five-ounce serving for women3. There are no health benefits for exceeding this amount and there are many risks.
