1, Ganoderma lucidum

Ganoderma lucidum can enhance human immunity; This is because Ganoderma lucidum contains polysaccharide with anticancer effect, and in addition, it is rich in germanium. Germanium can accelerate human metabolism, delay cell aging, and exert its anticancer effect by inducing human body to produce interferon, thus improving immunity.

2. Fresh radish

Because it is rich in interferon inducer, it has immune function.

3, ginseng royal jelly

Can improve immunity and endocrine regulation, and contains bee lactic acid with anticancer effect.

4. Mushrooms, Hericium erinaceus, Volvariella volvacea, Auricularia auricula, Tremella fuciformis, Cheyang, Lily, etc.

Both of them have obvious effects of enhancing immunity.

5. Mushrooms

Lentinus edodes contains lentinan, which can enhance human immunity.

Nutritional elements for improving immunity

1, protein, the "founder" of antibody formation

Antibody is an indispensable weapon in the process of maintaining immunity against the outside world. Protein is the basis of antibody formation, and the lack of protein directly affects antibody synthesis, which is equivalent to fighting without a sword. There are many foods rich in protein. Milk, eggs, lean meat and soybeans are all good sources of high-quality protein.

2. Vitamin C, the "catalyst" for antibody formation

Vitamin C is an antioxidant, which can reduce the external interference to the intracellular balance of human body, promote the formation of antibodies and maintain normal immunity. The most abundant foods of vitamin C are fresh fruits and vegetables, such as broccoli, Chinese cabbage and tomatoes.

Hawthorn, kiwi fruit, papaya, strawberry, etc. However, it should be reminded that vitamin C is very delicate and can be easily destroyed by long-term heating. When cooking, it is best to choose water blanching and quick frying.

3. Vitamin A, the "patron saint" of the first line of defense

Lack of vitamin A can easily lead to the atrophy of epithelial cells of respiratory tract mucosa and the decrease of cilia, and the first line of defense of human body will not work, leading to the invasion of bacteria into the body. Animal foods are rich in vitamin A, such as animal liver and cod liver oil.

There is a certain correlation between the content of vitamin A in plant food and the color. Generally speaking, orange and dark green fruits and vegetables (carrots, pumpkins, broccoli, spinach, etc.) provide beta carotene. ) can be converted into vitamin a in the human body.

4. Zinc is a "good helper" to regulate immunity.

Zinc is a component of more than 65,438+000 enzymes in human body, which plays an important role in the development of immune system and the maintenance of normal immune function. There are two kinds of foods rich in zinc: marine shellfish and mushrooms, and other foods rich in animal liver, lean meat and pecans.

5. Iron is the strong backing of antibody formation.

Iron deficiency will reduce the number of immune cells, and then affect the production of antibodies, leading to immune response defects. You can eat some "iron supplements" appropriately, such as animal liver, animal blood and red meat (lean pork, beef and mutton). There is another trick to supplement iron: vitamin C can promote the absorption of iron, so eating foods rich in vitamin C can play a strong role when eating foods rich in iron.

People's network-improve immunity, eat more than 5 kinds of food is effective.
