19.You may have noticed that you feel hungry a lot.This is natural----during teens,a person's body needs more nutrients(營養(yǎng)物質(zhì) to grow.Snacks are a great way to satisfy that hunger and get all the vitamins and nutrients your body needs.
But you need to pay attention to what you eat.Filling your stomach with a lot of fries after class may give you a short-time help,but a snack high in fat and calories will only slow you down in the long time.
To keep energy levels going---and avoid gain weight---keep away from foods like candy or soda.Look for foods like bread and grains and combine them with some food like peanut butter or low-fat milk or cheese.
