The best breakfasts have carbohydrates, protein, healthy fats, and fiber. In this combo, the oatmeal gives you complex carbs and fiber, keeps your blood sugar under control, and helps maintain an ideal balance of bacteria in your gut. The nut butter adds protein and healthy fats. The fruit tops it off with fiber and vitamins, plus it gives your breakfast a sweet taste. Avoid pre-packed oatmeal mixes that have added sugar and use old-fashioned oats instead.
