It should come as no surprise that triathlete Sarah Haskins is fond of a Greek food -- after all, she is an Olympian. The U.S. multisport athlete only has water when her running sessions are at an easy pace and less than 45 minutes in duration. But when they go longer than that, she goes with Greek yogurt. Greek yogurt has been growing in popularity with endurance athletes and it's packed with protein.
You certainly don't have to eat it plain, either. Haskins adds honey, almonds and fruit [source: Haskins]. It almost sounds like a dessert, but it's good for you. You can't beat that.
