Red wine in moderation (1 or two glasses per day) is healthy. Resveratrol, the compound that exhibits anti-cancer properties and provides cardiovascular protection, is in fact a polyphenol derivative of red wine. Resveratrol, an anti-aging nutrient, is said to mimic the effects of calorie restriction. Resveratrol is actually at the core of the so-called "French Paradox". French cuisine is dense with rich butter, animal fat, sauces, cheeses, and wines, yet the French enjoy superior cardiovascular protection, thanks to resveratrol in red wine. Nevertheless, it may neither be practically viable nor medically advisable to get your full resveratrol supplementation from red wine alone, as one litre of red wine delivers less than 5mg of resveratrol.
