1. Food provides our bodies with the substances needed for growth, health, and energy. It comes from plants like fruits and grains or animals like meat. 2. A balanced diet consists of eating foods from the five major food groups: grains, vegetables, fruits, dairy, and proteins. This ensures our bodies get all necessary vitamins, minerals, and nutrients. 3. The digestive system breaks down food through a multi-step process starting in the mouth and ending in the intestines, allowing our bodies to absorb useful parts and eliminate waste.
