Immunity refers to the ability of the body to resist foreign invasion and maintain internal stability. The air is full of all kinds of microorganisms: bacteria, viruses, mycoplasma, chlamydia, fungi and so on. In the case of insufficient human immunity, everyone can become the pathogen of early shift. Although the human body will produce corresponding antibodies against different pathogens to resist reinfection, antibodies are specific and time-limited. For example, streptococcus antibodies can only protect the body from reinfection by streptococcus for a short time, and they cannot resist infection by other viruses. A person with low immunity can't resist the attack of cold virus at all, which is the real reason why he often catches a cold. Daily diet conditioning is the most ideal way to improve human immunity;

1, drink more yogurt: adhere to a balanced diet, if people have alcoholism, mental stress or unbalanced diet, it will weaken people's disease resistance. To correct this imbalance, we must rely on health-preserving bacteria, which are contained in yogurt.

2, drink more boiled water: remember, it is boiled water! This can keep the mucosa in the nasal cavity and oral cavity moist; Drinking more water can also make people refreshed and energetic. Studies have proved that boiled water has ideal physiological activity on human metabolism. Water is easily absorbed by human body through cell membrane, which enhances the activity of lactate dehydrogenase in human organs, thus effectively improving human body's disease resistance and immunity. Especially the first cup of cold boiled water in the morning is particularly important.

3, eat more seafood: seafood is rich in iron, zinc, magnesium, selenium, copper and so on. Regular consumption can promote immune function.

4. Drink tea regularly: Scientists have found that tea contains a chemical called theanine. Because it can mobilize human immune cells to resist bacteria, fungi and viruses, and can improve human anti-infection ability by more than 5 times.

5. Drink some red wine: Most alcoholic beverages will inhibit the human immune system, but red wine, on the contrary, contains some antioxidants that are good for enhancing immune function and protecting the heart.

6, eat some animal liver: animal liver contains folic acid, selenium, zinc, magnesium, iron, copper, and vitamins B6, B 12. These substances help to promote immune function.

7. It is found that Cordyceps sinensis can effectively increase the number of cells and tissues in the immune system, promote antibody production, increase the number of phagocytes and killer cells, and reduce the function of some immune cells, which is the first choice to enhance human immunity. Formula: Choose good quality Cordyceps sinensis, take it after crushing, once 1.5g, twice a day, and take it continuously for 10 day. Most patients can achieve remarkable curative effect.

8. Appropriate iron supplementation: Iron can enhance immunity; However, excessive iron intake is harmful to the health, and it should not exceed 45 mg per day.

9. Glutamine supplementation: it is an indispensable and non-essential amino acid for human body, and it can be called one of the "sharp weapons" to strengthen the immune system. People who often catch cold or have loose bowels can take glutamine powder in fruit juice or cold boiled water.

10, arginine supplement: sea cucumber, eel, loach, cuttlefish, yam, black sesame, ginkgo, tofu skin, frozen tofu, sunflower seeds and hazelnut are all rich in this substance, and eating more will help enhance immunity.

1, Sea Cucumber: Sea Cucumber is rich in more than 50 kinds of known medicinal components such as sea cucumber glycoside and sea cucumber mucopolysaccharide, and is rich in trace elements such as SOD, collagen, "flower of life" zinc and selenium, vitamin B2 and 6-pulse blood, tonifying kidney and replenishing essence, strengthening yang and treating flaccidity, and relieving fatigue and symptoms.

2, Ganoderma lucidum: Ganoderma lucidum can enhance human immunity, this is because Ganoderma lucidum contains anticancer polysaccharides, in addition, it is also rich in germanium. Germanium can accelerate metabolism, delay cell aging, and exert its anti-cancer effect by inducing human body to produce interferon;

3, fresh radish: because it is rich in interferon inducer, it has immune function.

4. Ginseng: Ginseng mainly contains ginsenoside, ginsenoside and ginseng polysaccharide.

5, royal jelly: can improve human immunity and endocrine regulation, and contains bee lactic acid with anticancer effect.

6. Mushrooms, Hericium erinaceus, Volvariella volvacea, Auricularia auricula, Tremella fuciformis, Cheyang, Lily, etc. Both of them have obvious effects of enhancing immunity.

7. Lentinus edodes: Lentinus edodes contains lentinan, which can enhance human immunity.

8.SOD (Superoxide Dismutase) removes excess free radicals in the human body and is the golden key to overcoming diseases and resisting aging. Improve immunity, reduce triglyceride, lower blood sugar, repair human cells and resist fatigue. Optimism, adequate rest and sleep, proper exercise and correct nutrition all contribute to healthy immunity. ......

What can children eat to enhance their immunity?

Food that can enhance immunity

The first phase of healthy food: tea, papaya juice, tomatoes, oranges, oranges and carrots.

Drinking tea can enhance the resistance to bacteria.

Drinking tea will keep you away from the doctor. A new study believes that theanine contained in tea can enhance the body's resistance, which is not available in coffee.

A study published in the new issue of Proceedings of the National Academy of Sciences said that researchers from brigham Women's Hospital and Harvard Medical School found in laboratory experiments that tea contains a substance that can make the immune system attack invading bacteria, viruses and molds.

Papaya juice can enhance immunity.

Luc Montagnier, president of the World AIDS Research and Prevention Foundation, said that the juice extracted from fermented papaya can enhance human immunity and fight against some viruses, including SARS, but there is still a lack of research in this field.

Montagnier said: "Papaya juice contains some substances that can improve immunity and antioxidant capacity. Although we have not studied the oxidation ability of SARS patients, I think it is feasible. " Montagnier said that he had recommended this extract to his colleagues to treat French SARS patients.

Eating oranges and tomatoes can prevent diseases.

Improving self-immunity is one of the effective ways to prevent SARS. In recent days, the sales of vitamins and American ginseng in some pharmacies have increased greatly. However, medical experts warn that taking these supplements will not be immediate, and it will take at least a week to take effect.

According to experts, proper vitamin supplementation can enhance human immunity. Healthy people had better absorb vitamins by eating fruits and vegetables. At present, tomatoes, strawberries, carrots and oranges, which are widely sold in the market, contain a lot of vitamins.

Eating carrots in spring enhances immunity.

Relevant data show that the lack of vitamin A in children is the main cause of respiratory diseases. Experts emphasize that lack of vitamin A can easily cause respiratory and digestive tract infections. Once a cold or diarrhea occurs, the level of vitamin A in the body will further drop. Vitamin A deficiency can also reduce the body's antibody response, leading to decreased immune function. The protective effect of vitamin A on respiratory tract and gastrointestinal mucosa has been widely confirmed.

Supplementing vitamin A from food is a safe and effective health care method. Among many foods, carrot is the best way to supplement vitamin A. To fully absorb carotene, the scientific and reasonable way to eat it is: carrots should be cooked before eating, and the best cooking methods to maintain their nutrition are two points: First, cut carrots into pieces, add seasonings, and stir-fry with enough oil; The second is to cut carrots into blocks, add seasonings, and stew them with pork, beef and mutton in a pressure cooker 15-20 minutes. Carotene is easily oxidized. When cooking, stewing in pressure cooker can reduce the contact between carrots and air, and the preservation rate of carotene can reach 97%.

The second stage: animal liver, seafood, mushrooms, Pleurotus ostreatus, garlic, yogurt and spinach.

In the struggle between human immune system and viruses, bacteria and other pathogens, it is of great significance to improve self-immunity. Generally speaking, the stronger the immune function of the human body, the less likely it is to be attacked by viruses, and even if it is unfortunately infected, the degree of the virus can be minimized.

A balanced diet and reasonable nutrition are helpful to improve human immunity. Here are some dietotherapy methods that can enhance immunity:

Eat animal liver properly. Anne Mackenzie, a Canadian nutritionist, believes that animal liver is rich in many substances that help to promote immune function, such as trace elements selenium, zinc, copper, magnesium, iron and folic acid, vitamin B6 and vitamin B 12.

Eating more seafood, oysters, scallops, razor clams, marine fish and other foods is rich in zinc, which can promote the production of T cells and antibodies. Dr spector's research in the United States found that zinc helps to restore the damaged immune system function.

Eating anti-virus substances such as mushrooms, shiitake mushrooms, Grifola frondosa, Pleurotus ostreatus and Hericium erinaceus can help to enhance immunity.

Eating garlic can activate T lymphocytes and macrophages and enhance immunity.

Have some yogurt. The latest research found that yogurt can produce interferon-γ, improve the activity of natural killer cells and promote the production of antibodies.

Eat more fruits and vegetables, such as spinach, carrots and cauliflower. , rich in beta carotene, can promote the increase of immune cells, and rich in vitamin C, fruit with certain antiviral effect. For example, eat two oranges or oranges every day.

Drink more tea According to the research of Dr. Jack bukovski of Harvard Medical School, drinking five cups of tea a day can enhance the body's disease resistance. The reason is that L- theanine contained in tea can be decomposed into ethylamine by liver, which can enhance γ-δT in immune system. ......
