Disease analysis: Hello, sesame, malt and Chinese herbal medicine Astragalus are the first foods rich in selenium, followed by yeast, eggs and beer. Red shrimp, lobster, Tiger Claw fish and tuna are the best seafood, followed by meat such as animal liver and kidney, while fruits and most vegetables contain little selenium, but garlic and mushrooms are quite abundant, and asparagus contains selenium. Suggestions: The high selenium content in food does not mean that people will absorb it. Generally speaking, the utilization rate of organic selenium in fungi is high, which can reach 70%-90%, while the utilization rate of selenium in fish and grains 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.
