title: Nutrition and athletic performance.
abstract: Athletes and physicians alike are often poorly informed about nutrition. Myths abound, some of them potentially harmful. Common errors include a disproportionately high intake of proteins (especially by weight lifters), vitamins and minerals in excess of the recommended dietary allowances, poorly designed weight gain or loss programs, and various food fads.
