===Meaning===
[[File:BalanedDiet.png|right|300px|thumb|Four plates showing a '''balanced diet'''.]]
Having a '''balanced diet''' means eating a variety of food to make sure you get the right amount of; [[carbohydrate]]s, [[protein]]s, [[fat]]s, [[vitamin]]s, [[mineral]]s and [[fibre]].
===About a Balanced Diet===
: We need a '''balanced diet''' to stay healthy.
: Carbohydrates and fats provides us with energy for respiration.
: Proteins, vitamins and minerals in food are used for growth and repair.
: Fats and minerals help keep our [[Nervous System|nervous system]] healthy.
In a '''balanced diet''' we need to make sure we get enough:
*[[Carbohydrate]]s - To provide energy for respiration.
*[[Protein]]s - To provide material for growth and repair.
*[[Lipid|Fats]] - For our [[Nervous System|nervous system]] to function.
*[[Vitamin]]s - For growth and repair.
*[[Mineral]]s - Four growth, repair and our [[Nervous System|nervous system]] to function.
*[[Fibre]] - To aid digestion.
*[[Water]] - To aid digestion and keep us hydrated.
: '''Note''' - [[Fibre]] and [[water]] are not [[nutrient]]s, but they are an important part of a '''balanced diet'''.
====Carbohydrates====
: Carbohydrates can be split into two groups. [[Polysaccharide|Complex Carbohydrate]]s like [[starch]] which are very important in our diet and [[Sugar|Simple Carbohydrate]]s called [[sugar]]s that can be harmful if we eat to much of them.
