Efficacy: Selenium also has the functions of enhancing human immunity, protecting liver, caring skin, resisting aging and resisting heavy metal toxicity. In addition, the elderly have weak resistance and are prone to illness, and selenium supplementation can just enhance their resistance.

Extended data:
Yu Shuyu, a professor at the Cancer Institute of China Academy of Medical Sciences, said: Humans can synthesize vitamins, but they can't synthesize selenium. The human body needs less than 100 micrograms of selenium every day, but without it, it will get sick and even die. China is a selenium-deficient country, with 22 selenium-deficient provinces, accounting for about 72% of China's land area. According to statistics, more than half of the population in China have insufficient selenium intake. Therefore, it is necessary to supplement selenium to residents in selenium-deficient areas.
Selenium supplementation begins with eating. The high selenium content is mainly animal kidneys, seafood, plants, fungi and so on. But the kidney is the internal organs of animals, with high cholesterol content and unacceptable taste; Seafood is low in cholesterol and high in protein, but it is more expensive. Selenium-enriched agricultural products, such as eggs, meat, garlic, fungi, especially selenium-enriched flour, are good sources of selenium.
Flour is the staple food. Combining selenium supplement with pasta conforms to the eating habits of northerners, which not only establishes a stable selenium supplement channel, but also is a simple and good method. The dietary guidelines for Chinese residents recommend that adults consume 50 micrograms of selenium per day, and the maximum tolerable intake is 400 micrograms per day.
