While whole grains in general are healthy, oatmeal has additional benefits: It's naturally high in fiber, which helps keep blood-sugar levels stable and contains B vitamins, which are essential to convert carbohydrates into energy. Choose steel cut or Irish oatmeal over rolled oats. Oatmeal is a great high-energy food. Try it with almond milk and fresh or dried fruit.
