Just as gasoline is turned into energy that makes a car run, your body gets nutrition and energy from the foods you eat. Foods provide nourishment by giving your body vitamins and minerals naturally, when you eat the right foods. Good nutrition keeps your body healthy and builds the body’s immune system to make it strong to fight against illness. Good nutrition also helps your body heal faster when you get cuts and scrapes. Even though you may take a vitamin each day, the best vitamins and minerals are found in foods.
