Balanced diet

There are 7 components of a healthy diet:

  • carbohydrates
  • protein
  • lipids and fats
  • vitamins
  • fibre
  • water

There are 3 reasons why we need a healthy diet:

  • to supply us with energy
  • to provide materials for growth and repair
  • to help fight disease and keep our body healthy

If we don't eat the correct amount of each of these food groups and do not have a balanced diet, then we will not be able to carry out the life processes and so will be unable to live a healthy life.

Balanced diet: A balanced diet is a diet consisting the right proportions of every nutrient in suitably sized portions
