1. Selenium is an essential nutrient for the human body. In 1973, the World Health Organization announced to the world that selenium is an essential trace element for human and animal life. In 1988, the Chinese Nutrition Association announced that the trace element selenium was included as one of the 15 dietary nutrients we must consume every day, and the daily supplementary amount of selenium in the diet was not less than 50 micrograms.
2. Selenium deficiency can cause human diseases. Recent medical research has proven that selenium deficiency in the human body is related to more than 40 diseases such as cancer, hypertension, hyperlipidemia, diabetes, and cardiovascular and cerebrovascular diseases.
● Selenium is an anti-cancer factor
In the 1970s, Professor Yu Shuyu, a famous expert from the Institute of Oncology, Chinese Academy of Medical Sciences, and others worked hard for 16 years to establish an epidemic in areas with high incidence of liver cancer. The medical survey found that the selenium content in the blood of residents in areas with a high incidence of liver cancer is lower than that in areas with a low incidence of liver cancer. The incidence of liver cancer is negatively correlated with blood selenium levels.
She provided selenium supplements to 130,000 residents in Qidong County, Jiangsu Province and confirmed that selenium supplementation can reduce the incidence of liver cancer by 35% and reduce the incidence of patients with a family history of liver cancer by 50%.
In the study, it was found that sodium selenite regulates the cyclic nucleotide metabolism system in liver cancer cells, indicating that selenium prevents the division of cancer cells.
The above scientific and technological achievements won the "Schwarz Prize" awarded by the International Association of Bioinorganic Chemistry in 1996.
3. The anti-cancer effect of selenium has been confirmed. The U.S. Food and Drug Administration (FDA) allows selenium-rich foods and selenium-rich health products to be labeled as anti-cancer foods with cancer-suppressing effects. A university cancer research center in the United States analyzed more than 1,000 cases of cancer and announced that selenium has a very clear relationship with the incidence of cancer. If we supplement selenium, the incidence of human cancer can be reduced by 40%. In my country, selenium can prevent cancer and has been included in the third-year junior high school chemistry textbook and the medical trace elements and health textbook. Increasing selenium supplementation can reduce the incidence of prostate cancer by 63%, colon cancer by 58%, and lung cancer by 45%. In recent years, studies have found that selenium is closely related to mortality in cancer patients. According to epidemiological surveys, cancer patients in areas with high selenium content have a low mortality rate, while cancer patients in areas with low selenium content have a high mortality rate.
The per capita selenium content in Yangzhong City, Jiangsu Province, is 58% lower than that in Beijing, and the mortality rate of cancer patients is 2.6 times higher than that in Beijing. The Chinese Academy of Medical Sciences conducted a further investigation into the addition of selenium to Yangzhong City salt five years later and found that the overall mortality rate of cancer patients dropped by 12%.
4. Scientific selenium supplementation is urgent
Selenium, like other nutrients, participates in the metabolism of the human body, so we must take in sufficient amounts of selenium every day to maintain the normal metabolism of the body, otherwise Once selenium supplementation is stopped, the ability to defend against disease will be reduced.
Getting enough selenium from food is a safe supplement. Foods containing more selenium in daily life include seafood, meat (especially animal kidneys), and cereals such as rice.
