Besides beer yeast, wheat germ, garlic, asparagus, mushrooms and sesame seeds, foods rich in selenium also include many seafood, such as prawns, tuna and sardines. In addition, some plants have selenium-enriched ability, such as astragalus, sedge, Zi Yuan, atriplex, alfalfa and so on. For example, if the selenium content per gram of yellow flower is 10 mg and alfalfa is 32- 122 μ g, Brassica vegetables in Cruciferae also have strong selenium enrichment ability. It should be pointed out that the high selenium content in food does not mean that people will absorb it high. Generally speaking, fungi have a high utilization rate of organic selenium, which can reach 70%-90%, while the utilization rate of selenium in fish and grain is low, only about 70%. Therefore, the correct way to absorb selenium is to eat more foods that strengthen and supplement organic selenium, such as selenium-enriched yeast and selenium-enriched garlic. In addition, eating more fruits, vegetables and other foods rich in vitamins A, C and E will help to absorb selenium. In fact, foods rich in selenium are also rich in vitamin E, and these two nutrients interact. Foods rich in zinc are: meat, seafood, poultry, all kinds of beans, nuts and other foods.
