Bananas, the convenient superfood you can carry around with you in your pocket. These yellow-skinned fruits have an all-around pleasing taste and can be eaten alone or blended into smoothies or baked into breads. Bananas provide an abounding amount of energy as they have two times as many carbohydrates as an apple, five times as much Vitamin A and iron and three times as much phosphorus. In addition, bananas are also rich in potassium and natural sugars. Toss out the caffeine and eat a banana as a midday snack when you're feeling tired and sluggish.
