The Claim: It’s the special antioxidants in wine that make it an overall health promoter. The Bottom Line: Antioxidants are compounds found in certain foods, including wine, apples, dark chocolate, and tea. Wine contains a special type of antioxidant called flavonoids (part of the polyphenol family), known for particular heart-healthy effects. But the sweeter the wine, the lower the antioxidant content. So for the highest concentration of them, look for a dry red wine. Studies support drinking in moderation: for women, a 5-ounce serving daily (one regular-sized wine glass) or less for optimal health benefits.
