Macro nutrients:
Carbohydrates - are important because they give us energy. Carbohydrates are stored in the muscles and liver as glycogen, which is quickly converted to glucose and used to provide energy.
Fats - are important because they provide energy and, together with glycogen, help muscles work.
Protein - helps build muscles and repair damage to muscle tissue. Protein is also used to provide energy when working for a long period of time and all the carbohydrate has been used up.
Micro nutrients:
