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 the body's metabolism, delay the aging of cells, and exert its anti-cancer 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

Nutritional elements for improving immunity

1, protein, the "founder" of antibody formation

Antibody is an indispensable weapon in the process of human body fighting against the outside world to maintain immunity. 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, an antioxidant, can reduce the external interference to the intracellular balance of human body, promote the formation of antibodies and maintain normal immunity. The foods with the richest vitamin C are fresh fruits and vegetables, such as broccoli, Chinese cabbage, tomatoes and so on.

Hawthorn, kiwi fruit, papaya, strawberry, etc. However, it needs to be reminded that vitamin C is very delicate, and it is easy to be 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 atrophy of epithelial cells of respiratory tract mucosa, decrease of cilia, and the first line of defense of human body will not be effective, leading to the invasion of bacteria into the body. Vitamin A is rich in animal foods, such as animal liver and cod liver oil.

The content of vitamin A in plant foods has a certain correlation with color. Generally speaking, beta carotene provided by orange and dark green fruits and vegetables (carrots, pumpkins, broccoli, spinach, etc.) can be converted into vitamin A in human body.

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

Zinc is a component of more than 100 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 they are also rich in animal liver, lean meat, pecans and other foods.

5. Iron is the strong backing for antibody formation.

Iron deficiency can 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 also a trick to supplement iron: vitamin C can promote the absorption of iron, so when eating foods rich in iron, eating foods rich in vitamin C can play a strong role.
