Why do we need carbohydrates in our diet?

Carbohydrate is the main source of energy and comprises the main bulk of the average human diet. For your brain, heart and nervous system to function properly, a constant supply of carbohydrate is needed.

Once digestion has occurred, all forms of carbohydrate are converted into a sugar called glucose. Glucose is the main source of energy for muscles and other parts of the body. Before you workout you need to ensure your muscles are well fuelled.

How much you need depends on how active you are. The more active you are the more carbohydrate you need to fuel your muscles. A good guide to whether you are eating enough is how energetic you feel during your workout. If you fatigue easily, then this suggests that your glycogen levels are low and your carbohydrate intake is insufficient.
