Different foods provide a different amount and selection of nutrients:some give us energy and keep us warm; others are needed for growth and repair, to keep muscles and nerves healthy, or are needed for the development of healthy bones and teeth.
Our use of energy varies at each stage of our life and needs to be balanced with our intake of food.
