2. People who need selenium supplement include: patients with liver diseases, patients with cardiovascular diseases, diabetics, cancer patients, patients with gastrointestinal tract, people engaged in toxic and harmful work, people who are prone to fatigue, long-term smokers, teenagers, and malnourished children who often catch colds; Old people who long for health and longevity.
1, nutritional value of selenium:
1. Selenium has anticancer effect. Selenium deficiency in human body is prone to liver cancer, lung cancer, gastric cancer, esophageal cancer, renal cancer, prostate cancer, bladder cancer, cervical cancer and leukemia.
② Selenium has antioxidant effect. Selenium is the best anti-aging substance.
③ Selenium can enhance human immunity. Selenium deficiency reduces human immunity.
④ Selenium can antagonize harmful heavy metals. Selenium deficiency can easily lead to poisoning symptoms of heavy metals such as lead, arsenic and cadmium.
⑤ Selenium can regulate the absorption and utilization of vitamin A, vitamin C, vitamin E and vitamin K. Selenium deficiency can cause myopia, cataract, retinopathy and other diseases.
⑥ Selenium can regulate the synthesis of protein. Selenium deficiency can cause energy deficiency malnutrition and chromosome damage in protein.
⑦ Selenium can enhance reproductive function. Selenium deficiency can cause symptoms such as blocked ejaculation, low sperm motility, deformity, decreased pregnancy rate and increased incidence of metritis.
Selenium is an important component of muscle function. Selenium deficiency can cause skeletal muscle atrophy and gray stripes, myocardial injury, myocardial cell density change, lipid increase and calcium deposition, leading to diseases.
Therefore, men need to supplement selenium more, because most of the selenium supplied to the body is concentrated in the reproductive organs and can be excreted together with semen. In particular, residents living in highly polluted areas and residents living in selenium-deficient areas need selenium supplementation.
Because there is no organ in the human body to store selenium for a long time, the selenium needed by the human body should be continuously obtained from the diet. The balance of selenium concentration plays an important role in protecting and promoting the physiological functions of many organs and tissues.
When selenium is deficient, it will easily lead to the decline of human immunity. More than forty diseases that threaten human health and life are related to selenium deficiency, such as cancer, cardiovascular diseases, liver diseases, cataracts, pancreatic diseases, diabetes, reproductive system diseases and other symptoms.
2, selenium supplement method:
Selenium deficiency can be supplemented by food supplement and medicine supplement. According to the test results of trace elements in the body, human body should follow the principle of "no matter how much selenium is lacking, no matter how much selenium is lacking, food supplement is the main one, supplemented by medicine".
Foods that contain more selenium in daily life include seafood, meat (especially the kidneys of animals), rice and cereals. Eggs contain more selenium than meat. For example, per 100g of 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. Besides wheat germ, garlic, asparagus, mushrooms and sesame seeds, foods rich in selenium also include many seafood, such as prawns, tuna and sardines.
There are many ways to supplement selenium. Animal organs, seafood, fish, eggs and meat are all good sources of selenium. Eating more of these foods can supplement selenium safely and effectively. If you want a more comprehensive supplement, you can take it directly from selenium supplements. At present, there are many kinds of selenium-containing health products and foods on the market, namely selenium nutritional supplements. Whether eating these selenium-containing products can correct selenium deficiency lies not in its content, but in its conversion rate. At present, malt selenium and yeast selenium are mainly supplemented in the market, among which malt selenium is the highest stage of selenium development at present, and its transformation and absorption are better than yeast selenium. Selenium deficiency can be corrected by supplementing malt selenium with selenium Weikang chewable tablets for 3-6 months, and its component vitamin E can also effectively prevent excessive selenium supplementation and avoid selenium poisoning.
3. People who need selenium supplementation:
Patients with liver diseases should be supplemented with selenium: the serum selenium concentration of patients with viral hepatitis, fatty liver and liver cirrhosis is obviously lower than that of normal people, because when the selenium intake of people is insufficient, the activity of glutathione peroxidase in the liver will drop sharply, so that harmful peroxides produced in liver metabolism can not be removed in time, leading to various diseases in the liver. Quantitative selenium supplementation can eliminate metabolites in the liver in time, help the liver decompose toxins, improve autoimmune function, improve the condition and prevent liver cancer.
Patients with cardiovascular diseases should be supplemented with selenium: selenium deficiency is an important factor leading to coronary heart disease, arteriosclerosis, hypertension and cardiovascular diseases. Quantitative selenium supplementation can protect myocardial cells, prevent myocardial fibrosis, improve ventricular contraction and relaxation performance, regulate arrhythmia and protect the heart from ischemia and hypoxia injury. Selenium can also reduce cholesterol and triglyceride, prevent atherosclerosis, reduce blood viscosity, activate blood flow state, reduce thrombosis, promote the healing of injury after embolization and reduce the area of myocardial infarction. Treating and preventing cardiovascular diseases with selenium has gradually become a new trend in the domestic medical field.
Diabetic patients should be supplemented with selenium: selenium deficiency is an important factor of diabetes. Proper intake of selenium can ensure the normal function of pancreas and prevent the destruction of islet β cells. Selenium has a similar effect to insulin, which can protect and restore the function of pancreas, improve the metabolic regulation of diabetes and reduce the level of glycosylated hemoglobin in urine. Especially for diabetic complications (cataract, edema of lower limbs, cardiovascular diseases, etc.). ).
Cancer patients should be supplemented with selenium: "Selenium" is praised by scientists at home and abroad as "the king of cancer" and "the god of cell protection" because selenium can control the growth and differentiation of tumor cells and block two important energy sources of cancer cells. An energy source of cancer cells is that the oxygen glycolysis rate of cancer cells is eight times that of normal cells, and selenium can obviously inhibit this glycolysis rate. Another energy source of cancer tissue is oxidative phosphorylation, and selenium can also effectively inhibit its development. Selenium can also reduce the toxic and side effects of chemotherapy and radiotherapy, and reduce the toxicity of cisplatin to kidney, bone marrow and intestine in chemotherapy, which is an ideal antidote for cisplatin. In a word, using selenium to prevent and cure cancer and relieve the pain of cancer patients has become the latest new measure advocated by the scientific community.
Patients with gastrointestinal tract should be supplemented with selenium: diseases such as chronic gastritis and peptic ulcer are, in the final analysis, caused by toxins such as bacteria and free radicals in the digestive tract. Selenium can not only remove peroxides and free radicals in the gastrointestinal tract, but also directly inhibit intestinal pathogens, adjust the balance of gastrointestinal environment, repair and protect mucous membranes, and is a good product for treating gastritis and digestive tract ulcers. Constipation patients are especially suitable.
People who are engaged in toxic and harmful work should supplement selenium: serious environmental pollution and the large use of chemical fertilizers in modern society are serious threats to human health. It is urgent to supplement selenium quantitatively, because selenium is a natural antidote, which can discharge harmful metal ions, such as lead, cadmium, mercury, arsenic, thallium, tin and other activities that damage the kidney, gonad and central nervous system of human body, play a role in detoxification and relieve teratogenic and carcinogenic toxicity induced by harmful factors in the environment. In addition, people who are often exposed to radiation interference such as TV, computers and mobile phones in their working environment or life should be supplemented with selenium, because selenium supplementation can protect the hematopoietic system and minimize radiation damage.
People who are prone to fatigue and addicted to tobacco and alcohol for many years should supplement selenium: Selenium is a good antioxidant, and its antioxidant performance is 500 times that of vitamin E, which can give you enough oxygen to resist fatigue, make you refreshed, and reduce the formation or even disappearance of spots. Quantitative selenium supplementation can remove foreign toxins inhaled, protect cells from free radical damage and repair the physiological damage of smokers. Long-term smokers need 20 years to completely eliminate toxins from their bodies after quitting smoking, so they need 200 micrograms of selenium every day to completely eliminate toxins from their bodies within 3 months. Long-term drinkers will damage the liver, such as alcoholic fatty liver and other serious people suffer from cirrhosis. Quantitative selenium supplementation can accelerate catabolism, relieve discomfort after drinking, protect the liver and gradually recover stool symptoms.
Teenagers, malnourished children who often catch colds; Old people who long for health and longevity should be supplemented with selenium: quantitative selenium supplementation can improve the oxygen carrying capacity of red blood cells, so that children's brains can get enough oxygen, and they are not prone to fatigue, drowsiness and lack of concentration during heavy study. It can greatly improve immunity, promote growth and kill pathogens (such as cold virus and hepatitis virus). ) and make teenagers and children grow up healthily. With the growth of age, people and metabolism gradually slow down, so there are more and more waste gases in the body. Quantitative selenium supplementation can increase the phagocytic ability of macrophages and the ability to kill bacteria, expel the waste gas from the body in time and maintain the "green environment" in the body. This can not only delay aging, but also reduce the common symptoms of depression, insomnia, anxiety and fatigue in the general elderly. According to scientific investigation, the selenium content in the eyeball of cataract patients is only one sixth of that of normal people. Quantitative selenium supplementation can make eye hydrolase reach the best working state, improve eye circulation and eliminate toxins, thus achieving the purpose of improving cataract. Fundamentally improve the health level and quality of life of the elderly.
