As the saying goes, "selenium" is the most expensive thing. Everything that is combined with "selenium" is generally very expensive. Among the various nutrients required by the human body, selenium is a mineral nutrient that has been widely circulated in recent years. Some businesses use this as a promotional point to prescribe many selenium-enhancing health products. Selenium-enhancing foods are known to supplement selenium and can solve various health problems.
There are also many middle-aged and elderly friends now eating various foods rich in selenium to supplement the selenium in the body, but what is the real function of selenium? How much do you need to replenish every day? Can it be supplemented through a normal diet? Few people pay attention to these issues. Let’s learn about these issues together.

First of all, let’s understand what is selenium element and what are its benefits to the body?
Selenium element refers to non-metallic element with chemical symbol Se. It is a trace element in the human body and is one of the non-metallic elements. The highest content of selenium in the human liver shows that most patients with liver disease lack selenium, which acts as a non-specific immune system activator, promotes the function of the immune system and protects liver cells from hepatitis B virus, etc.
In addition, selenium has the effect of antioxidant and removing free radicals in the eye tissue. Selenium deficiency may cause diseases such as cataract , night blindness, etc. Selenium can regulate the secretion of thyroid hormones. Selenium is a component of glutathione peroxidase and has the effect of inhibiting the destruction of islet B cells.
When selenium acts on the human body, it has certain antioxidant effects, regulates the absorption and utilization of vitamins, promotes the excretion of toxins, regulates fertility functions, and improves immunity.
. Antioxidant, regulates the absorption and utilization of vitamins: Selenium is one of the components of glutathione peroxidase. Glutathione peroxidase can resist free radicals and achieve antioxidant and anti-aging effects. Selenium can also play a certain role in regulating the absorption and utilization of vitamins in the human body.
. Promote the excretion of toxins and regulate fertility functions: Selenium is a negatively charged non-metal ion, which can combine with the positively charged harmful metal ions present in the human body to achieve the effect of detoxification and detoxification.
. Selenium has the effect of promoting the development of reproductive organs and gonads, and has a certain effect of regulating fertility functions.
4. Improve immunity: Selenium can activate DNA repair enzymes, which can stimulate the human body to produce immunoglobulin , antibodies, improve the vitality of prophages, and improve immunity.
5. Improve the blood oxygen capacity of red blood cells: Selenium can protect red blood cells , prevent the hemoglobin in red blood cells from being oxidized, enhance the ability of blood oxygen , and maintain the normal function of cells.
6. Prevention of cancerous tumors: Selenium can inhibit a variety of potential carcinogens, kill cancer cells, reduce the side effects of chemotherapy, and reduce the pain in patients with advanced cancer.

selenium supplementation has four benefits in addition to preventing cancer! Which foods to eat more can supplement selenium
. Prevent cardiovascular diseases, g mountain disease : Selenium has a strong antioxidant effect, can prevent cardiomyocyte damage caused by the accumulation of lipid peroxides, has a protective effect on the myocardial muscle, and can promote the repair and regeneration of damaged myocardial muscles. The mortality rate of hypertension in selenium-deficient areas, heart disease and coronary heart disease is three times higher than that in selenium-rich areas.
also found that the mortality rate of rheumatic heart disease, cerebral thrombosis and atherosclerosis is also significantly lower in high selenium areas than in low selenium areas. Keshan disease is an unknown cause, mainly myocardial necrosis, and the incidence rate in low selenium areas is quite high. The basic factor of Keshan disease is selenium deficiency, and selenium supplementation can prevent the occurrence of Keshan disease.
. Protect the liver: Selenium can be used as a protective factor for anti-hepatic necrosis. When selenium is deficient, liver selenium reserves decrease, liver metabolic function is dysfunction, resulting in damage and necrosis of liver peroxides. Give appropriate selenium is helpful for the treatment of chronic hepatitis,
. Prevent diabetes : Diabetic patients have significantly lower selenium concentration than healthy people, thus blocking the removal of free radicals, pancreas atrophy, pancreatic cell dysfunction, insulin secretion, and abnormal glucose tolerance of lead to diabetes. Selenium has several insulin-like effects, so selenium has certain significance for the treatment and prevention of diabetes and its complications.
4. Relieve asthma diseases: The effect of metabolites produced by lipid peroxide on bronchial smooth muscle is one of the pathogenesis of asthma . It can cause edema of bronchial smooth muscle and produce a strong contraction effect on bronchial smooth muscle, causing airway stenosis. and selenium-containing enzyme glutabenoperoxidase have the function of inhibiting lipid peroxide.

What kind of food can be eaten to supplement selenium?
. Seafood foods: The selenium content in seafood is generally much higher than that in crops and poultry, especially squid, sea cucumber , cuttlefish , razor clams , oysters, scallops, shrimps, sea crab , sea fish and other animal seafood. The selenium content is generally higher than 50 micrograms/100 grams. Eating seafood regularly can prevent selenium deficiency.
. Foods rich in selenium: In addition to seafood, many natural foods themselves contain relatively rich selenium elements, such as konjac , matsutake mushroom, flower bean , pig kidney, beef kidney , sheep kidney, duck liver , river crab, etc. The zinc content is generally more than 50 micrograms/100 grams. The selenium content in animal foods is generally higher than plant foods, especially animal offal and eggs.
. Specially cultivated selenium-rich food : For many people, the easiest method of replenishing selenium is to purchase selenium-rich foods specially cultivated in the market. Most selenium-rich foods are crops grown in soil rich in selenium, or poultry, livestock, meat, egg products, etc. fed with selenium-rich feed, such as selenium-rich rice, selenium-rich corn, selenium-rich wheat, selenium-rich peanuts, selenium-rich soybeans, selenium-rich potatoes, selenium-rich tea, selenium-rich eggs, etc.
4. Selenium supplement health products: If you really have serious selenium deficiency and need some special selenium supplement preparations, you need to use protein selenium , selenium malt powder, yeast selenium , Shanchuang Tablets, zinc selenium treasure, selenium-rich milk powder and other selenium supplement medicines or health products under the guidance of a doctor. The safety and utilization rate of organic selenium is higher than that of inorganic selenium, and is more suitable for selenium supplementation.
