While you might focus on meats as a good source of protein, they also contain a number of essential vitamins and minerals. The vitamins and minerals found in meats help boost your energy, balance your blood pressure and keep your immune system healthy. Choose mostly lean meats, such as skinless poultry, pork loin and beef tenderloin, to limit your intake of saturated fat.
