Scientific research has found that blood selenium level is closely related to the occurrence of cancer. A large number of survey data show that the selenium content in food and soil in an area is directly related to the incidence of cancer. For example, if the selenium content in food and soil in this area is high, the incidence and mortality of cancer will be low, otherwise, the incidence and mortality of cancer in this area will be high. Facts show that selenium is closely related to the occurrence of cancer. At the same time, the scientific community also recognizes that selenium is the "king of cancer" among trace elements in human body.
Enhance immunity:
Organic selenium can scavenge free radicals, eliminate toxins, resist oxidation, effectively inhibit the production of lipid peroxide, prevent thrombosis, remove cholesterol and enhance human immune function.
Prevention of diabetes:
Selenium is the active component of glutathione peroxidase, which can prevent the oxidative damage of islet β cells, make them function normally, promote glucose metabolism, reduce blood sugar and urine sugar, and improve the symptoms of diabetic patients.
Prevention of cataracts:
Selenium can protect retina, enhance the smoothness of vitreous body, improve vision and prevent cataract.
Prevention of cardiovascular and cerebrovascular diseases:
Selenium is an important element to maintain the normal function of the heart, which can protect and repair the heart. The decrease of human blood selenium level will lead to the decrease of the function of scavenging free radicals in the body, which will lead to the increase of harmful substances deposition, the increase of blood pressure, the thickening of blood vessel wall, the decrease of blood vessel elasticity, the slow blood flow and the decrease of oxygen transport function, thus inducing the increase of the incidence of cardiovascular and cerebrovascular diseases. However, scientific selenium supplementation has a good effect on preventing cardiovascular and cerebrovascular diseases, hypertension and arteriosclerosis.
Prevention of Keshan disease, Kaschin-Beck disease and arthritis;
Selenium deficiency is the main cause of Keshan disease, Kaschin-Beck disease and two endemic diseases. Selenium supplementation can prevent bone marrow lesions, promote repair, and promote disulfide bond resistance to metal detoxification in protein synthesis. It has good preventive and therapeutic effects on patients with these two endemic diseases and arthritis.
Detoxification and detoxification:
Selenium has a strong binding force with metals and can resist the toxicity of cadmium to kidney, gonad and central nervous system. Selenium combines with mercury, tin, thallium, lead and other heavy metals in the body to form a metal selenoprotein complex, which plays the role of detoxification.
Prevention and treatment of liver diseases and protection of liver;
Yu Shuyu, a medical expert in China, found that the blood selenium content of residents in high-incidence areas of liver cancer was lower than that in low-incidence areas of liver cancer, and the incidence of liver cancer was negatively correlated with the blood selenium level. Selenium supplementation in Qidong County, Jiangsu Province can reduce the incidence of liver cancer and the incidence of patients with family history of liver cancer.
Bengbu Xiweikang Biotechnology Co., Ltd. developed selenium-enriched rice and tea according to the national health organization standards, and the organic selenium content per kilogram reached 100-300 micrograms, which successfully opened up a safe and effective new channel for human selenium deficiency.
Butter, fish meal, lobster, mushroom, pig kidney, garlic and other foods contain a certain amount of selenium, but the absorption rate is not ideal. Nutritionists advocate supplementing organic selenium, such as selenium polysaccharide, selenium yeast, selenium eggs, selenium-enriched mushrooms, selenium-enriched malt, selenium-enriched gastrodia elata, selenium-enriched tea and selenium-enriched rice.
The relationship between selenium intake and soil selenium content is greater than that with diet. Soils in the United States and Canada seem to contain enough selenium. Studies on vegetarians and vegans in the United States found that they consumed enough selenium. Selenium exists in many foods, but Brazil nuts, whole grains (whole wheat bread, oatmeal, barley), white rice and beans are particularly abundant.
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. The selenium content of plant food is determined by the selenium content in local soil and water. For example, the selenium content of grain produced in high selenium areas in China is as high as 4~8 mg/kg, while that in low selenium areas is 0.006 mg/kg, with a difference of 1000 times.
