2. Kiwifruit. Kiwi contains selenium, calcium, potassium, trace elements and 17 amino acids, and is also rich in vitamin C, gluconic acid, fructose, citric acid, malic acid and fat.
3. grapes. Grape contains trace elements such as protein, carbohydrate, crude fiber, calcium, selenium, lecithin, carotene and vitamins. In addition, it also contains more than ten kinds of amino acids and a lot of fruit acids needed by human body.
4. longan. Longan meat contains a lot of glucose, protein, vitamins, various amino acids, calcium, selenium and other elements, which is warm and sweet, beneficial to the heart and spleen, qi and blood, and has a good nourishing and strengthening effect.
5.asparagus. The selenium content of asparagus is higher than that of ordinary vegetables, close to selenium-enriched mushrooms, and even comparable to that of marine fish and shrimp.

The efficacy of selenium:
1, cancer prevention. Scientific research has found that the level of selenium in blood is closely related to the occurrence of cancer, so selenium is also known as the "king of cancer" among trace elements in human body. Selenium has inhibitory effects on cancers such as colon cancer, gastric cancer, leukemia, liver cancer and breast cancer.
2. Enhance immunity. Nutrients such as selenium, vitamin E, zinc and linoleic acid have synergistic antioxidant effects, which can scavenge free radicals in the body, inhibit the generation of lipid peroxide, prevent thrombosis and improve human immunity.
3. Prevent cataracts. The selenium content in the lens of myopic cataract is lower than that of normal people. Studies have shown that proper selenium can prevent the formation of cataract to some extent.
4. Prevent cardiovascular and cerebrovascular diseases. Selenium is an antioxidant nutrient, which can scavenge free radicals, reduce the deposition of harmful substances on blood vessel walls, and prevent the decrease of blood vessel elasticity and thickening of blood vessel walls. Scientific selenium supplementation is helpful to prevent cardiovascular and cerebrovascular diseases such as hypertension and arteriosclerosis.
5. Enhance reproductive function. Selenium is an essential component of peroxidase in semen. Selenium deficiency will reduce the activity of this enzyme, resulting in a decrease in the number of sperm, an increase in dead sperm and a decrease in fertility.
6. Anti-aging. Selenium has stronger antioxidant capacity than vitamin E, so it has anti-aging effect. If the human body lacks selenium for a long time, it will age before it grows old.
