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

The efficacy of selenium:
1, prevent cancer. 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 colon cancer, gastric cancer, leukemia, liver cancer, breast cancer and other cancers.
2. Enhance immunity. Selenium, vitamin E, zinc, linoleic acid and other nutrients have synergistic antioxidant effect, which can scavenge free radicals in the body, inhibit the production of lipid peroxide, prevent thrombosis and improve human immunity.
3. Prevent cataracts. The selenium content in lens of myopia cataract and other eye diseases 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 the blood vessel wall, prevent the decrease of blood vessel elasticity and the thickening of blood vessel wall, etc. 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, which will lead to the decrease of sperm number, the increase of dead sperm and the decrease of 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.
