<p><b>New page</b></p><div>Energy is required for all metabolic reactions which allow the body to carry out its functions: growth and maintenance of a healthy body is achieved by a regular intake of nutrients in food.<br />
<br />
Foods which supply energy:<br />
Three main nutrients provide the body with energy.<br />
* protein<br />
* fat - provides the most concentrated source, weight for weight.<br />
* carbohydrate - important source of energy. Carbohydrate acts as a 'protein sparer' so that the protein can be used for its primary functions.<br />
<br />
The main energy supplying foods are:<br />
* fats - ie. butter<br />
* oils - ie. vegetable oil<br />
* fatty foods (eg. egg yolk and cheese) sugar, cereals and starchy vegetables.<br />
<br />
The amount of energy used by the body is the energy expenditure which differs from individual to individual:<br />
<br />
* Young children require more energy for their size than adults due to rapid growth.<br />
<br />
* Physical Activity v. sedentary workers - i.e. a clerical employee requires less energy than a very active worker - i.e. a coal miner.<br />
<br />
* Basal Metabolism or resting metabolism - where the energy is released to keep the body alive - i.e. for warmth.<br />
<br />
* Losing Weight - the energy intake from food must be less than the energy used for body activity, in this way the body is forced to use fat as its energy source.<br />
