2. Ganoderma lucidum: Ganoderma lucidum can enhance human immunity, because Ganoderma lucidum contains polysaccharide with anticancer effect, in addition, it is rich in germanium. Germanium can accelerate the metabolism of the body, delay the aging of cells, and exert its anti-cancer effect by inducing human body to produce interferon.
3. Fresh radish has immune function because it is rich in interferon inducer.
4. Ginseng: Ginseng mainly contains ginsenoside, ginsenoside alcohol and ginseng polysaccharide.
5. Royal jelly: It can improve the body's immunity and endocrine regulation ability, and contains bee lactic acid with anti-cancer effect.
6. Mushrooms, Hericium erinaceus, Volvariella volvacea, Auricularia auricula, Tremella fuciformis, Cheyang, Lily, etc. all have obvious effects of enhancing immunity.
7. Lentinus edodes: Lentinus edodes contains lentinan which can enhance human immunity.
8. Vitamins: Vitamins can enhance human immunity. Healthy people had better absorb vitamins by eating fruits and vegetables. Vitamins have immune function because they are rich in interferon inducers. Eat more foods rich in vitamin C. Vitamin C is indispensable to human body, which can reduce capillary permeability and make it a barrier to prevent viruses from entering human tissues and protect organs.
9. Collagen: It is an extracellular protein, which is a fibrous protein twisted by three peptide chains. Collagen is the most abundant protein in human body, accounting for more than 3% of the total protein. Rich in glycine, proline, hydroxyproline and other amino acids needed by human body. Collagen is the most important component of extracellular matrix.
1. Chicken soup: It can prevent upper respiratory tract infectious diseases such as colds and flu. Chicken contains a variety of amino acids necessary for human body, which is rich in nutrition, especially cysteine, which can enhance the body's immunity. In addition, drinking chicken soup also has a positive effect on accelerating recovery after infection.
11. Garlic and onion: Garlic and onion are both hot foods, which have a good effect on improving physical fitness. Garlic has the function of sterilization and antivirus, and it is best to eat garlic raw, because raw garlic has the function of antivirus and improving immunity. Allicin, an effective component in garlic that can enhance immunity, will lose its efficacy during heating. Onion is also a natural sterilization and antivirus food, which can effectively resist viruses and bacteria.
12. Foods containing zinc: Zinc is an indispensable trace element in human body, and many enzymes in human body can only function with zinc, which is very important for regulating immune function. In addition, zinc can also resist infection. Taking 5 ~ 1 mg of zinc every day can prevent influenza. Seafood, lean meat, coarse grains and legumes are all rich in zinc. Zinc is a component of many important enzymes in the human body, which can catalyze life activities, help children improve their immunity and participate in the metabolism of vitamin A.
13. papaya juice: papaya juice contains some substances that can improve immunity and antioxidant capacity.
14. Milk immune protein: According to the principle of breast-feeding immune response, a variety of active immune substances such as immune protein in the milk of healthy dairy cows are separated and extracted by biochemical hyperimmunity technology, and then optimized, recombined and superimposed to form bioactive proteins with high purity and rich in various antibody factors, which can regulate the immune function of the body.
15. Whey lactoferrin: It contains main immunoglobulin and growth factor and other essential components for human growth and development. In milk, the ratio is only 1: 7, which is very precious.
