Carbohydrates are also known as Sugars and Starches, and are the fundamental energy source for our bodies. They can be simple molecules (glucose, sucrose and fructose) or complex conglomerations of these two basic units.

Breads, cereals and leafy green vegetables are the major sources of Carbohydrates. Carbohydrates yield the most amount of energy when metabolised by the body, and travel in the blood as a ready source of energy for cells.
