Put Down the Wine Bottle

It’s great if you exercise, but you don’t want what you eat and drink to negate even part of the gains you make. In a recent study published in The Journal of Physiology, researchers at the University of Copenhagen took a look at the effect of resveratrol—the compound found in red wine—on the body.
Twenty-seven sedentary but healthy men between the ages of 60 and 72 took either resveratrol or a placebo every day and participated in interval training twice a week for eight weeks. By the end of the study, men who took the placebo had better oxygen capacity than those who took resveratrol.
Researchers concluded that exercise is better than a pill for your health, and too high a level of antioxidants in the blood might even block the effect of cardiovascular exercise in some people such as older men, making it harder to reduce blood pressure and cholesterol levels. (However, the amount of antioxidants administered in the study was much higher than what you can get in a regular diet.)
