Carbohydrates provide the main source of our body’s fuel that keeps it up and running. Choosing the right carbs is important. Complex carbs such as whole wheat pasta, rice, oatmeal, and green vegetables are bulkier and take longer to digest and release all their energy. It is also important to remember that carbs are also found in all fruits and vegetables when counting your carb intake for the day. They should account for 60 percent of your diet, especially if you are active.
