China is a major selenium-deficient country. According to the "China Endemic Diseases and Environmental Atlas", about 700 million people live in low-selenium areas accounting for 72% of my country's land area. Selenium supplementation in the human body is related to hundreds of millions of people. As a matter of great importance to people's health, we should do a good job in selenium supplementation just like iodine supplementation. Now that the environment is seriously polluted, almost everyone needs selenium supplements. People exposed to environmental pollution should take selenium supplements. Many human diseases are caused by environmental pollution, and selenium is a natural detoxifier. Selenium, as a negatively charged non-metal ion, can combine with positively charged harmful metal ions in the human body, such as lead, cadmium, mercury, arsenic, thallium, tin, etc., decompose, reduce and excrete them out of the body, completely digesting the metal ions toxicity. For people who have long been addicted to smoking and drinking, are engaged in toxic and harmful operations, and are exposed to radiation, chemical, and air pollution, quantitative selenium supplementation can detoxify the body in time and improve their health. A survey conducted by the Chinese Nutrition Society in 13 provinces and cities in my country showed that the average daily selenium intake of adults from food is 26-32 micrograms, which is far from the minimum limit of 50 micrograms recommended by the Chinese Nutrition Society. The Chinese scientific community has called for The current internationally popular method - "food fortification method" is used to solve the problem of selenium deficiency. "Food fortification" means adding nutrients that the human body lacks to daily food. But a safer and more effective way is to consume natural selenium-rich products to supplement selenium. Compared with health products, natural selenium-rich foods are simple, easy, safe, effective and harmless to the human body.
