Nutrition is how living things get and use food. A balanced diet contains the right amounts of each class of food.
There are seven classes of food: carbohydrates (energy), proteins (growth and repair), fats (energy store), vitamins, minerals, water and fibre (helps digestion).
Remember
- 7 classes: carbohydrate, protein, fat, vitamin, mineral, water, fibre.
- Carbohydrates give energy; proteins build the body.
