What is the function and efficacy of selenium?

The functions and efficacy of selenium are as follows:

1, the king of cancer

Scientific research has found that blood selenium level is closely related to the occurrence of cancer. A large number of survey data show that the level of selenium in food and soil in a region is directly related to the incidence of cancer. Selenium is the most important anti-aging element discovered so far.

2. The Messenger of Light

Selenium is extremely important for the function of visual organs. Selenium can catalyze and eliminate free radical substances harmful to eyes and protect the cell membrane of eyes. If the human eye is in a state of selenium deficiency for a long time, it will affect the integrity of cell membrane, leading to decreased vision and many eye diseases such as cataract, retinopathy and night blindness. Selenium has obvious effect on improving vision, and can be used to treat cataract, retinopathy and other eye diseases.

3, the patron saint of the soul

Selenium is an important element to maintain the normal function of the heart, which can protect and repair the heart. The decrease of human blood selenium level will lead to the decrease of free radical scavenging function in the body, which will lead to the increase of harmful substance deposition, the increase of blood pressure, the thickening of blood vessel wall, the decrease of blood vessel elasticity, the slow blood flow and the decrease of oxygen transport function.

Therefore, the incidence of cardiovascular and cerebrovascular diseases has increased. However, scientific selenium supplementation has a good effect on preventing cardiovascular and cerebrovascular diseases, hypertension and arteriosclerosis.

4. Natural enemies of liver disease

Qidong City, Jiangsu Province, located in the Yangtze River Delta, is a land of plenty and developed economy. However, for a long time, the incidence of liver cancer and hepatitis here is extremely high, and the reasons are still unclear. Selenium can improve the condition of hepatitis patients and greatly reduce the proportion of cancer in hepatitis patients. Experts said: Even in the surrounding areas where selenium is not lacking, it is of great benefit for people to supplement selenium in moderation to prevent liver cancer and hepatitis.
