In recent years, more and more selenium-enriched foods have appeared in the Internet and shopping malls, such as selenium-enriched eggs, selenium-enriched rice, and selenium-rich noodles. In addition, there are news reports that Wuhan Yishao only buys selenium-rich rice. Non-selenium-rich rice does not eat. Selenium-enriched foods are divided into natural selenium-enriched foods and artificial organic selenium foods; natural selenium-enriched foods are crops grown in soils with high selenium content, and artificial organic selenium-enriched foods are introduced into organic selenium during the growth stage. A food containing high levels of selenium produced by crops. So what is selenium? What are the benefits of selenium for the human body? Which foods contain high levels of selenium? What is selenium? Selenium is an essential trace element in the human body, which is found in various organs and body fluids of the human body, with the highest concentration in the kidney. Selenium, like Vitamin E, is a powerful antioxidant that scavenges the attack of free radicals on biofilms and protects them from oxidative damage. It is also involved in the synthesis of various selenoses and selenoproteins in the human body. Selenium cannot be stored in the human body for a long time, so the human body should constantly consume a sufficient amount of selenium from the diet. The reference intake of dietary nutrients for Chinese residents released in 2017 pointed out that the daily intake of selenium in Chinese adults is 60-250 micrograms, and the maximum is no more than 400 micrograms. If the body is deficient in selenium, it will lead to a decrease in immunity and an increase in the incidence of cancer. What is the benefit of selenium to the human body? prevent cancer Scientific research has found that the level of selenium in the blood is closely related to the occurrence of cancer, so selenium is also known as the "king of anti-cancer" in human trace elements. Selenium has inhibitory effects on colon cancer, gastric cancer, leukemia, liver cancer, breast cancer and other cancers. Enhance immunity Selenium and vitamin E, zinc, linoleic acid and other nutrients have synergistic antioxidant effects, can eliminate free radicals in the body, and inhibit the production of lipid peroxides, prevent thrombosis and improve human immunity. Prevention of cataract The lens selenium content of myopic cataract and other eye diseases patients is lower than that of normal people. Studies have shown that the right amount of selenium can prevent the formation of cataract to a certain extent. Prevention of cardiovascular and cerebrovascular diseases Selenium is an antioxidant nutrient, which can scavenge free radicals, reduce the deposition of harmful substances on the blood vessel wall, prevent the elasticity of blood vessels from decreasing, and thicken the blood vessel wall. Scientific selenium supplement can help prevent cardiovascular and cerebrovascular diseases such as hypertension and arteriosclerosis. Enhance reproductive function Selenium is an essential component of peroxidase in semen. Selenium deficiency can reduce the activity of this enzyme, which leads to a decrease in the number of sperm and an increase in dead sperm, resulting in decreased fertility. Selenium is more resistant to vitamins than vitamin E, and therefore has an anti-aging effect. If the body is deficient in selenium for a long time, it will not prematurely decline. Which foods contain high levels of selenium? Seafood: Most seafood is rich in selenium, such as caviar, sea cucumber, dried squid, dried mussels, river crab, dried squid, dried squid, shrimp, oysters, scallops, prawns, shrimps, small yellow flowers. Fish, abalone, squid, scorpion, golden thread, sardine, red snapper, tuna, sea crab, etc. Eggs: Eggs also contain high levels of selenium. Each 100g of egg contains about 23.3 micrograms of selenium, 100g of duck egg contains 30.7 micrograms of selenium, and 100g of goose egg contains 33.6 micrograms of selenium. Meat: The selenium content of pork is quite high in meat foods, containing 10.6 micrograms of selenium per 100g pork. Secondly, pig kidney, beef kidney, sheep kidney and duck liver also contain a lot of selenium. Mushrooms: Edible mushrooms such as red mushrooms, pine mushrooms, and pearl white mushrooms are rich in selenium, which is one of the best sources of selenium in the body. Regular consumption is beneficial for improving immunity and enhancing disease resistance. Others: garlic, konjac flour, purple potato, black tea, flower beans, mustard, wheat germ powder.
Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.
