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

Drinking tea will 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 says 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 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 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

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 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 in spring enhances immunity

Relevant data show 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, carrot is the best vitamin A supplement. 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 liver, seafood, mushrooms, oyster mushrooms, garlic, yogurt, spinach

In the fight against viruses, bacteria and other pathogens, it is of great significance to enhance self-immunity. 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 Ann Markenki believes that animal liver is rich in many substances that help promote immune function, such as trace elements selenium, zinc, copper, magnesium, iron and folic acid, vitamin B6 and vitamin B12.

Eating seafood such as oysters, scallops, razor clam and marine fish 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 to enhance immunity.

Eating garlic can stimulate the activity of T lymphocytes and macrophages and enhance immunity.

Drink some yogurt. The latest research found that yogurt can stimulate the body to produce γ-interferon, 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 which are rich in vitamin C and have certain anti-virus infection effects. For example, eat two oranges or oranges every day.

Drink more tea. According to 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 the L- theanine contained in tea is decomposed into ethylamine by the liver, which can enhance the γ-δT cell reaction in the immune system < P > Phase III: hawthorn, seabuckthorn, spiral bath, aloe, ginger, propolis, milk and soybean < P > When it comes to disease prevention, many experts remind people to enhance their immunity. The immune system plays an important role in people's health. Play to strengthen physical fitness. Besides regular exercise and maintaining psychological balance, a reasonable diet is also very important. Here are several foods that can obviously enhance the immune function of the body.

Crataegus pinnatifida: Crataegus pinnatifida is deeply loved by people. Its main functions are helping digestion, protecting cardiovascular system, lowering blood lipid and blood pressure, resisting bacteria, losing weight, resisting tumor, scavenging free radicals and enhancing immunity.

Garlic: Garlic has antibacterial and anti-inflammatory effects, which can protect the liver, regulate blood sugar, protect the cardiovascular system, resist hyperlipidemia and arteriosclerosis, and resist platelet aggregation. Nutrition experts have found that garlic extract has anti-tumor effect, and it is recommended to eat 3-5 grams of garlic raw every day.

Hippophae rhamnoides L.: Hippophae rhamnoides L. grows in semi-hilly areas, and is rich in vitamin C, which can promote hematopoietic system, resist fatigue, protect digestive tract, scavenge free radicals, improve vascular system and enhance immunity.

Spirulina: The protein content of Spirulina is as high as%-7%, and its biological value is 68%. Spirulina is rich in carrots, vitamins, vitamin E and other vitamins, which can improve the PH value of body fluids, correct acidic constitution, make human body slightly alkaline, thus improving human immunity, and has anti-tumor and anti-AIDS effects.

Aloe: Aloe, like Jinxiang, garlic, onion and wild lily, belongs to perennial herbs of Liliaceae. It mainly grows in dry and hot areas and has strong vitality. It can clear away heat and toxic materials, relieve diarrhea, diminish inflammation and bacteria, enhance immunity, protect stomach and liver, and protect skin and beauty.

Ginger: It is both a condiment and a nutrient. Its main functions are anticoagulation, blood lipid reduction and prevention of stroke. Sliced raw ginger has the best effect.

Lentinus edodes: Since ancient times, Lentinus edodes has been called "the elixir of life". It has an excellent filtering effect on the virus, and the "Mushroom Hot Pot Banquet" in Yunnan is a medicated diet for strengthening the body.

Propolis: Propolis can improve the ability of human macrophages to swallow viruses and bacteria, and make the body's immunity in the best state of dynamic balance, so it is called "natural immune enhancer".

Milk and soybeans: Both milk and soybeans are high-protein foods. The Anders-Heikensen research team of Lund University in Sweden found that casein and ovalbumin in milk can enhance the anti-infection ability of respiratory tract and internal organs and prevent viruses and bacteria from sticking to respiratory tract. Soybean protein in soybean is digested, absorbed and utilized by human body to a very high degree. It can form antibodies in the body as well as milk protein.
