Introduction
Sugars are a major form of carbohydrates and are found probably in all green plants. They occur in significant amounts in most fruits and vegetables. There are three main simple sugars sucrose, fructose and glucose. Sucrose is in fact a combination of fructose and glucose and the body quickly breaks down into these separate substances.

The Need For Energy
All energy stored in food is derived originally from the sun and it is made by green plant life. The sun's energy acts upon the green chemical "chlorophyll" in the leaves of plants to produce sugars and starches from the carbon-dioxide in the atmosphere and the water from the roots by a process known as Photosynthesis. These carbohydrates (starches and sugar) acts as a plants food and energy supply. The energy need of human body is largely dependent on the carbohydrates that are derived from plants.

A Balanced Diet
A balanced diet can come from a variety of different foods, calculated to give the desired levels of carbohydrates, proteins, fats, vitamins and minerals. Nutritional scientists advocate that carbohydrates should provide at least 50% of over energy requirements.
