Remember to eat from all the food groups every day. Our body needs more than 40 different nutrients. No one food has them all.

Scientists divide (划分) foods into five different types: dairy (奶制品), meat, grains (谷物), fruit and vegetables.

Every day, a junior high school student may need about six pieces of bread, 700 grams (克) of vegetables, three cups of milk, three apples and a small dish of chicken. But this isn't the same for everyone. It depends on your body type and how much exercise you get.
