If You Run, These 6 Foods Are a Must

Runners need protein to build muscle — much more protein than nonrunners — and lean proteins are the way to go. Beans are an excellent source of saturated-fat-free protein, and they also offer cholesterol-lowering fiber to keep your heart healthy. A half-cup serving of black beans offers 7 grams of protein and 6 grams of fiber. Add them to salads, soups, burritos, or salsas. Enjoy your beans a few hours before or after a workout since the high fiber content makes them difficult to digest.
