Whole grain oats are delicious and easy to digest before or after a workout. As an added bonus, the soluble fiber in oatmeal may help lower cholesterol. Opt for plain oats instead of the sugary flavored varieties and create your own delicious concoction by adding nutritious (and tasty) ingredients. Sprinkle in your favorite nuts and dried fruit to add natural sweetness as well as fiber and iron. Save time by cooking the oats ahead and warming them up in the microwave.
