2. Selenium-enriched malt A food selenium-enriched fortifier developed by Beijing Food Industry Research Institute. It is found that selenium-enriched malt can block the unscheduled synthesis of DNA from peripheral leukocytes by carcinogen AFBl.
3. Selenium-enriched tea is the tea cultivated in selenium-enriched areas. Among them, water-soluble selenium accounts for10% of total selenium. It is generally believed that the total selenium concentration in selenium-enriched tea should not be lower than1.5×10-6.
4. Selenium-enriched algae mainly belong to Chlorella of Spirulina. The product contains 20 ~ 200×10-6 selenium and1~ 25g vitamins.
5. Selenium-enriched eggs can be obtained by feeding inorganic selenium to poultry in a certain way. The highest selenium content of selenium-enriched egg yolk is 1.56× 10-6, and the highest selenium content of egg white is 0.34×10-6.
6. Selenium-enriched fruits are bioengineered, and inorganic selenium is absorbed and utilized through the growth process of the original food, and converted into organic selenium, which becomes a food with main anticancer factors such as carotene, vitamin C and cellulose. Selenium-enriched fruit is the perfect combination of "fairy fruit" and selenium, which makes ordinary fruit sublimate into natural nutritional functional food necessary for human body every day, and it tastes more delicious and has a more appropriate sweet and sour degree.

Black corn can not only satiate but also cure diseases, especially for children and pregnant women.
9. Garlic is rich in selenium. Selenium can promote the production of glutathione in human body, which has a strong anti-free radical effect. What is more gratifying is that Chinese scientists have confirmed that garlic also has anti-cancer effect. The incidence of gastric cancer in garlic producing areas and areas where garlic is eaten in China is very low, which is only equivalent to l/2000 in high-incidence areas. Garlic powder products can also reduce cholesterol by 8%, while fresh garlic or garlic extract can reduce cholesterol by15%. The lipid-lowering effect of garlic is related to allicin contained in garlic. Allicin has antibacterial and antitumor properties, and can prevent atherosclerosis, reduce cholesterol and triglyceride, and lower blood pressure.
