Background
Selenium is a necessary nutrient element for human body, and has anticancer effect, and human body is susceptible to liver cancer, lung cancer, gastric cancer, esophageal cancer, renal cancer, prostatic cancer, bladder cancer, cervical cancer, leukemia, etc. due to selenium deficiency; selenium has antioxidant effect. Selenium is the best anti-aging substance, and if a human body lacks selenium, the human body can be 'no longer young', and premature senility can be caused; selenium can enhance immunity. The lack of selenium reduces the immunity of the human body; selenium has the function of antagonizing harmful heavy metals, and the selenium deficiency is easy to cause poisoning symptoms of heavy metals such as lead, arsenic, cadmium and the like; selenium can regulate absorption and utilization of vitamin A, vitamin C, vitamin E, and vitamin K. Selenium deficiency can cause myopia, cataract, retinopathy, eyeground diseases, senile macular degeneration and other diseases; selenium has the function of regulating protein synthesis. Selenium deficiency can cause protein energy deficiency malnutrition, chromosome damage and the like; selenium can enhance reproductive function, and selenium deficiency can cause ejaculation obstruction, low sperm motility, malformation, low conception rate, and high metritis incidence. The existence of selenium in nature is divided into two categories: inorganic selenium and plant active selenium, wherein the inorganic selenium generally refers to sodium selenite and sodium selenate, and is obtained from byproducts of metal mineral deposits; the plant active selenium is formed by combining selenium with amino acid through biotransformation, generally exists in the form of selenomethionine, and is organic selenium which can be better absorbed and utilized by human bodies.
