There’s a song from the musical Oliver! called “Food, Glorious Food.” A group of children sing about “magical food, wonderful food, marvelous food, fabulous food.” Those words just about sum up most people’s feelings about eating.
Food is tasty. It makes the feeling of hunger go away. But most important of all, just like air and water, food is something your body needs for survival.
Foods contain nutrients. Those are substances that give the body energy. They help the body grow and keep it strong and healthy. Nutrition studies how the body uses nutrients and the best ways to get the nutrients your body needs. Carbohydrates, proteins, and fats are macronutrients. Macro- means “large.” Your body needs fairly large amounts of these. Vitamins and minerals are micronutrients. Micro- means “small,” and your body needs smaller amounts of these.
