Selenium-the King of Cancer Prevention
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. At present, it is very common to use selenium as adjuvant therapy in cancer treatment. Selenium is the most important anti-aging element discovered so far; Bama County, Guangxi is one of the four famous longevity areas in the world. The study of Bama by experts from Chinese Academy of Sciences shows that the selenium content in soil and grain in Bama is 10 times of the national average, and the selenium content in blood of centenarians is 3-6 times of that of normal people. Later, another longevity village was discovered in shitai county. The elderly over 80 years old account for 12% of the village population. More strangely, no cancer patients, cardiovascular and cerebrovascular patients, diabetic patients and obese patients have been found in the past 50 years. The analysis and determination of selenium content in the soil of this village showed that the selenium content was 10 times higher than that in other places. It turns out that selenium is the active component of antioxidant glutathione peroxidase. If the human body supplements enough selenium, it can effectively scavenge free radicals, resist oxidation and delay aging. In addition, some experts used selenium chewable tablets to supplement the clinical study of patients, and found that if vitamin E and β -carotene were supplemented in selenium, the effect would be better.
Selenium-the Messenger of Light
After long-term research, biologists have found that selenium is extremely important to the function of visual organs. Selenium can catalyze and eliminate free radical substances harmful to eyes, thus protecting the cell membrane of eyes. If the human eye is in a state of selenium deficiency for a long time, it will affect the integrity of cell membrane, lead to decreased vision, and lead to cataract, retinopathy, night blindness and other eye diseases. At present, some hospitals in big cities have carried out selenium treatment for patients with eye diseases. Clinically, selenium can obviously improve vision and treat eye diseases such as cataract and retinopathy.
Selenium-the patron saint of the heart
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.
Selenium —— Natural Enemy of Liver Disease
Qidong, Jiangsu, is located in the Yangtze River Delta, a land of plenty and developed economy. However, the incidence of liver cancer and hepatitis here is extremely high for a long time, and the cause is unknown. After 16 years of research, experts from Chinese Academy of Preventive Medicine finally found the reason. It turns out that the water, soil and grain here all lack the element "selenium". People living here get little selenium from water and grain, and the selenium content in their bodies is particularly low. People who lack selenium in their bodies are prone to hepatitis virus infection. In addition, the risk of hepatitis patients with long-term selenium deficiency turning into liver cancer patients is 202 times that of other people. It is particularly worth mentioning that selenium can improve the condition of hepatitis patients and greatly reduce the proportion of cancer in hepatitis patients. Experts said: Even in the surrounding areas where selenium is not lacking, it is of great benefit for people to supplement selenium in moderation to prevent liver cancer and hepatitis.
Selenium-insulin in trace elements
Selenium is the active component of glutathione peroxidase, which can prevent the oxidative damage of islet β cells, make them function normally, promote sugar metabolism, and reduce blood sugar and urine sugar. Doctors can protect and restore the function of pancreatic islets by letting diabetic patients take selenium quantitatively, which is beneficial to improve the symptoms of diabetes and reduce the levels of glucose and hemoglobin in urine. So some people call selenium "insulin" in trace elements.
Selenium-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. Therefore, people who are often exposed to toxic and harmful work need to pay special attention to selenium supplementation. In addition, in the working environment or life, people who are often exposed to radiation interference such as TV, computer and mobile phone should be supplemented with selenium, because selenium supplementation can protect the hematopoietic system and minimize radiation damage.
Selenium deficiency 1. Selenium deficiency can lead to premature aging. 2. Severe selenium deficiency can lead to cardiomyopathy and myocardial failure. 3. Keshan disease and Kaschin-Beck disease occur from time to time. 4. listlessness, decreased sperm vitality, and easy to catch a cold. Enshi, the selenium capital of the world: "The selenium content in rocks, soil, animals and plants in Enshi Autonomous Prefecture is the highest in the world", which brings good news to people in more than 70% selenium-deficient areas in the world, and the development and utilization of selenium products and selenium deposits have broad prospects. Dr. Yin Xuebin of China University of Science and Technology and others have discovered selenium-containing rocks with a concentration of over 10000 ppm in this area. Enshi has established strategic cooperative relations with China University of Science and Technology and Institute of Geographical Resources of China Academy of Sciences. At present, the national key development species. It is a selenium variety with market demand. 1, 199 1 year comprehensive development of selenium resources: selenium-enriched plant protein series products, health products, selenium-enriched tea, selenium mineral water and selenium-enriched cigarettes. 2. Special food resources: rare varieties such as water shield, Osmunda japonica, bracken, Dou Yun, konjac, Gexianmi, Fengjiang, Heming and yam. , is very famous at home and abroad. 3. Enshi City, Jianshi County and Xuanen County in this state are rich in selenium mineral water resources. The spring water contains 0.0 14-0.02 mg/L of selenium and more than a dozen beneficial elements such as strontium, zinc, calcium, magnesium and germanium. However, the selenium content in these areas is unstable and difficult to control, which affects the safety of selenium-enriched products.
