Oxidative damage in human body is an important cause of disease and aging.
Selenium can activate glutathione peroxidase, an important substance in human body's own antioxidant system, control and eliminate oxidative damage, thus preventing diseases. The antioxidant effect of selenium is 500 times higher than that of vitamin E.
Through scientific detection, the blood selenium of the elderly with long life is 3-6 times higher than that of normal people. Selenium can delay aging, reduce depression, fatigue and other phenomena, improve vision, prevent and treat cataracts, and fundamentally improve the quality of life of the elderly.
Second, protect and repair cells.
Selenium in the whole cytoplasm plays a special role in digesting and reducing antioxidants produced in the body's metabolic activities, and protects the cell structure from being destroyed by oxides. Only when the cells are intact can the organ function be normal. Protecting cells will protect the heart, liver, kidneys, lungs, eyes and other important organs of the human body.
Third, improve the oxygen carrying capacity of red blood cells.
Selenium protects red blood cells in blood, so that hemoglobin in red blood cells will not be oxidized, and it has strong oxygen carrying capacity, which can bring enough oxygen to every cell in the body and keep every cell in normal function.
Fourth, improve human immunity.
Selenium can enhance the immune system's ability to recognize viruses, foreign bodies and diseases in the body; Improve the antibody synthesis of immune system β cells, the proliferation of T cells and the antibody level in blood, and improve the phagocytosis and sterilization ability of macrophages by 2 times.
Selenium can improve the immune function of the body and fundamentally improve the resistance to diseases, which is an important reason why selenium can strengthen the body and eliminate diseases.
Verb (abbreviation of verb) detoxification, detoxification and resistance to the rule of law
Selenium, as a nonmetallic ion with negative charge, can combine with harmful metal ions with positive charge in human body and be directly excreted, completely eliminating the toxicity of metal ions and playing the role of detoxification.
Many human diseases are caused by living environment pollution. Common harmful elements that pollute the environment include lead, aluminum, mercury, cadmium, arsenic and thallium. A variety of poisoning symptoms caused by them can be digested by selenium to varying degrees. Selenium is a "natural antidote" against pollution.
VI. Prevention of cancer
Human cancer is caused by carcinogens in the environment (such as aflatoxin 0) and free radicals produced in the body (commonly known as "garbage in the body").
Selenium is the "king of anticancer" among trace elements. It can not only inhibit the carcinogenesis of various carcinogens, but also clean up free radicals in time, making them the killers of cancer cells. Selenium can block two important energy sources of cancer cells, increase the level of cyclic adenosine monophosphate in cancer cells, and form an internal and external environment to inhibit the division and proliferation of cancer cells in the body. Selenium can also reduce the toxic and side effects of radiotherapy and chemotherapy, and obviously alleviate the severe pain of patients with advanced cancer.
Selenium nutritional status is closely related to cancer, and people with low blood selenium level have high cancer incidence and mortality. The measure taken by Americans to prevent cancer is to supplement 200 micrograms of selenium per person every day.
The biological function of selenium makes selenium have magical functions such as protecting heart and brain, protecting liver and kidney, preventing cancer, restoring islet function and delaying aging. The blood selenium level of patients with chronic and intractable diseases such as liver disease, cardiovascular and cerebrovascular diseases, diabetes and cancer is very low. Proper selenium supplementation can enhance the self-healing ability at the same time of treatment.
