question 1: what can I eat to improve my immunity quickly? Foods 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 and keep you away from doctors. A new study believes that theanine contained in tea can enhance the body's resistance, and its effect is not available in coffee. A study published in the new issue of the Journal of the National Academy of Sciences said that researchers from brigham Women's Hospital and Harvard Medical College 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, chairman of the World AIDS Research and Prevention Foundation? Montagnier 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 oxidizing power 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 orange tomatoes can prevent diseases and improve 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 one 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, oranges and so on, which are widely sold in the market, contain a lot of vitamins. Eating carrots to enhance immunity in spring shows that the lack of vitamin A in children is a major cause of respiratory diseases. Experts emphasize that the lack of vitamin A is prone to respiratory and digestive tract infections. Once a cold or diarrhea occurs, the level of vitamin A in the body will further decline. 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, carrots are the best way to supplement vitamin A.. To fully absorb carotene, the scientific and reasonable eating methods are: carrots should be cooked before eating, and the best cooking methods to maintain their nutrition are two points: first, cut carrots into blocks, add condiments, and stir-fry them 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 for 15-2 minutes. Carotene is easy to be oxidized, and the contact between carrots and air can be reduced when cooking in a pressure cooker, and the preservation rate of carotene can be as high as 97%. Phase II: Animal livers, seafood, mushrooms, Pleurotus ostreatus, garlic, yogurt and spinach are of great significance in enhancing the immunity of the human body in the fight against pathogens such as viruses and bacteria. Generally speaking, the stronger the immune function of the human body, the less likely it is to be attacked by the virus. Even if it is unfortunately infected, the degree of virus attack can be minimized. A balanced diet and reasonable nutrition are helpful to improve human immunity. Here are some food therapies that can enhance immunity: eat animal liver properly, Canadian nutritionist Anne? Mackenzie 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 B12. Eating 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 immune system function that is being damaged. Eating mushrooms, shiitake mushrooms, Grifola frondosa, Pleurotus ostreatus, Hericium erinaceus and other antiviral substances will help enhance immunity. Eating garlic can activate T lymphocytes and macrophages and enhance immunity. Drink 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, cauliflower, etc., which are rich in beta carotene and can promote the increase of immune cells, and fruits rich in vitamin C and have certain anti-viral effects. For example, eat two oranges or oranges every day. Drink more tea, according to Harvard Medical School Jack? Dr bukovski studies that 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 the liver, which can enhance the γ-δT cell reaction in the immune system.

Food 5: Tomatoes can be said to be energetic food, which contains a variety of powerful antioxidant factors, such as lycopene, carotene, vitamins C and E, which can protect eyesight, protect cells from damage and repair damaged cells. It is good to eat tomatoes raw or slightly cooked. Adding a little olive oil can dissolve more lycopene, and the effect is better. Food 6: Yogurt infants are in the period of rapid physical growth and cranial nerve development, and the demand for protein and calcium is quite high. Therefore, dairy products are the best source of nutrition for infants. Yogurt is a kind of milk product, which can give consideration to nutrition and improve intestinal environment. It is very suitable for children's needs, and children can't drink it until they are one year old. Only when the immune system is good can children have a strong constitution.
