Carbohydrates, better known as sugars, are the favourite source of energy of our muscles.

Muscles obtain sugars from blood or from the body reserves as glucogen. The better known sugars are glucose and fructose, which are also known as simple sugars. When glucose binds to other simple sugars it forms polysaccharides, like for example starches.
Fibre is also formed by carbohydrate material, but our body digestive processes can't digest fibre. That is the reason why fibre has so many positive effects on our body health, especially those concerning intestinal physiology.

Carbohydrates are the most important fuel for our body. It is considered that our diet should contain 50-60% of carbohydrates. The main dietary sources of carbohydrates are bread, cereals, rice, pasta and fruits.

Muscles need minerals to be able to work correctly. In the muscles, calcium, sodium, magnesium and potassium work together and separately in different processes that allow our muscles to be healthy and able to satisfy our needs.

Calcium plays an essential role in muscle contraction physiology and in the maintenance of muscle tone, magnesium is necessary for the transmission of impulses to muscles and it also helps to control the strength of muscle contraction, among other important functions. Sodium and potassium are involved in the transmission of impulses to muscle tissue.
