1. White mushroom is a good food to supplement selenium, which is an indispensable trace element for human body. Scientists have confirmed that selenium is an important component of antioxidant in red blood cells, and sufficient selenium can promote this antioxidant to effectively convert hydrogen peroxide in human body into water; In addition, many selenium-containing enzymes can regulate the work of thyroid and participate in the synthesis of amino acids. Selenium can enhance the anti-cancer ability of human body and improve immunity. Supplementing 200 micrograms of selenium every day can significantly stimulate immune function, and the production of lymphocytes and neutrophils can be greatly increased. Both of these cells have the function of destroying tumor cells. According to epidemiological investigation, selenium supplementation has the most obvious effect on reducing the incidence of prostate cancer, lung cancer and liver cancer. Anti-cancer experiments conducted by researchers show that among people who take 200 micrograms of selenium preparation every day, the total cancer mortality rate is reduced by 50% and the total incidence rate is reduced by 37%. Among them, the incidence of prostate cancer decreased by 63%; The incidence of colon cancer decreased by 58%; The incidence of lung cancer has dropped by 46%. This anti-cancer effect is more obvious, especially after people with the lowest selenium concentration in the body are supplemented with selenium at the beginning of the experiment. Selenium can also prevent human immunity from being low. Studies have also shown that some elderly people's immunity has returned to the level of young people after taking enzyme preparations containing 100 micrograms of selenium every day for 6 months. Researchers advise people to eat selenium-rich foods in moderation, such as sesame, spinach and garlic, asparagus, mushrooms, prawns, tuna and sardines.

2. The human body needs very little selenium. If you eat normally, you generally don't need to supplement it specially. Too much selenium is harmful to health. Eggs contain more selenium than meat. In every 100g food, pork contains 10.6 micrograms, eggs contain 23.3 micrograms, duck eggs contain 30.7 micrograms, goose eggs contain 33.6 micrograms, ginseng contains 15 micrograms, and peanuts contain 13.7 micrograms. Seafood and so on. Selenium can protect cell membrane, play an important role in maintaining the normal structure and function of myocardial fibers and blood vessels, detoxify, reduce the toxin of aflatoxin B and protect liver cells. I hope these can help you solve your problem!
