Selenium is a necessary trace element for human body, which plays an important role in human health. Studies have shown that selenium can improve human immune function, has antioxidant, detoxification, anti-cancer and anti-cancer, repair cells and antagonize heavy metals and other functions. Selenium in the human body is mainly obtained from the daily diet, so the content of selenium in food directly affects the daily intake of selenium. The recommended dosage of selenium for different populations in China: 50 μ g / day for prevention of nutritional deficiency diseases, 100 μ g / day for sub-health care, 200 μ g / day for prevention of cancer and other major chronic diseases, and more than 200 μ g / day for intervention during treatment. Therefore, reasonable diet and scientific selenium supplement have become one of the healthy lifestyles, and selenium rich products in the market are more and more favored by consumers.

In the soil environment of China, the distribution of selenium is low in the middle and high in the southeast and northwest.

In the selenium deficient areas, various areas are also adjusting measures to local conditions, through appropriate exogenous selenium enhancement technology, to improve the selenium content of animal and plant products. At present, selenium rich products in various regions cover grain, tea, oil, vegetables, fruits, edible fungi, Chinese herbal medicine, layers, broilers, pigs, cattle, aquatic products and other kinds of processed products, so as to meet the daily dietary selenium supplement needs of consumers.
