One of the principles of eating a healthy diet is to eat only nutrient-dense foods, and to avoid those that contain empty calories. Nutrient-dense foods are those that provide healthful nutrients in the form of compound carbohydrates, high quality protein, healthy fats, vitamins, and minerals. On the other hand, foods that are high in calories but contribute little or nothing to your health are considered junk food, and you can simply live without them.
