Make sure to eat fruits and vegetables everyday. Oh, you should not only watch what you eat, but what you drink as well. Don't drown yourself in sodas, fizzy drinks and those lattes or mocachino. Too much carbonated drink and caffeine is not good for the body. Drink as much water as you can everyday. You can never go wrong with fresh fruit juices, too. If you like meat, then you can turn to chicken and fish instead of eating too much beef and pork.
