Why is this important?

Food provides the body energy for its functions, including internal and your day-to-day activities. Energy is measured in units of kilojoules or calories. By knowing the energy value of foods you can estimate how much you’re taking in to make sure you don’t consume more than you generally use.

A healthy, well-balanced diet has the right amount of energy for you, includes plenty of vegetables, along with fruit, lean proteins, grains and dairy, with a limited amount of salt, added sugar, and saturated fats.
