Dark chocolate is packed with epicatechins, powerful antioxidant compounds that have been proven to lower blood pressure, improve blood flow to the brain and reduce the risk of cardiovascular disease. A growing body of research indicates that epicatechins could have a positive impact on athletic performance by increasing cellular energy.
Dark chocolate is also high in fiber and iron. Usually the darker the chocolate, the higher it will be in useful nutrients. Look for organic chocolate labeled at least 70 percent cocoa to ensure you're getting the good stuff. As for serving size, most researchers agree you need no more than a 1-inch square a day to receive benefits.
