Believe it or not, eating sugar can be part of a healthy diet. Sugar is a carbohydrate, one of the three major macronutrients we need to survive (the other two are protein and fat). Sugar is found naturally in all kinds of foods including grains, fruits, dairy, and some vegetables. Sugars found in whole foods are actually good and necessary for most people. The body takes longer to digest foods that contain natural sugar and in turn, they offer your body a steady supply of energy.
