What are carbohydrates?
Carbohydrate is a large class of compounds composed of carbon, hydrogen and oxygen, and it is the most abundant organic matter on the earth. Foods containing more carbohydrates are generally cheaper; Moreover, carbohydrates are oxidized faster in the body and can supply energy in time to meet the needs of the body.
Therefore, carbohydrates are the most economical and main source of energy intake for most people. They are also an important part of the body, which are closely related to the normal metabolism of some nutrients in the body and have important physiological functions.
The role of carbohydrates:
Supply heat energy. Sugar is the main source of heat energy, and every 1g carbohydrate can provide 16.7kJ of heat energy. It is characterized by its large proportion in the total energy, rapid and timely energy supply, and the final products of oxidation are carbon dioxide and water, which are harmless to the body.
Detoxify. The level of glycogen in the liver is of great significance to the body's resistance to poisons and detoxification of certain chemicals. If the human body is rich in liver sugar, it has strong resistance to diseases, as well as carbon tetrachloride and ethanol. Toxic substances such as arsenic have a strong detoxification effect.
Save protein. Because the energy needed by the human body is mainly supplied by sugar, if the sugar supply is sufficient, it will not cause a lot of oxidation of fat in the body, produce too many ketone bodies, and cause ketosis; Will not lead to excessive decomposition of tissue protein, forming a burden balance.
