Scientific diet improves immunity

Pay special attention to the intake of protein and vitamins every day, because protein and vitamins play an important role in improving human immunity. The effect of fruits and vegetables on human health is irreplaceable by other foods. People with normal health should absorb vitamins by eating fruits and vegetables. At present, tomatoes, strawberries and carrots on the market contain a lot of vitamins, which are very well absorbed and balanced in the body.

People who are sickly or eat too little food can supplement some vitamin products under the guidance of a doctor, and remember the right amount. It is suggested to refer to "12345" for daily diet.

An egg and a little meat a day.

Two, 250 ml of milk or soybean milk

3,300 grams of grain

Four, 400 grams of fruit

5500 grams of vegetables

Diet is a highly personalized behavior, so we should balance our diet according to our own situation. "Things are beautiful and evil, and it is a disaster to go too far." Eating is a process, not a day's work. People should develop good eating habits in their daily life. If you didn't care before, start now!

Diet improves immunity

Yu hong

At present, the prevention and treatment measures of atypical pneumonia in clinical medicine are mainly to control the source of infection, cut off the route of transmission and protect the susceptible population. One of the hot spots in the field of nutrition research is to study and find foods and health products that can enhance human immunity and prevent diseases. This also fully embodies the idea of "homology of medicine and food" in ancient medical books in China more than two thousand years ago. Improving diet structure is the best strategy to control diseases and restore health.

Supplement high-quality protein.

Protein is the key substance for human body to fight against pathogen infection, and human health depends on antibody, an important protein with immune function in blood. Can resist the infection of various viruses, bacteria, mycoplasma and other pathogens.

At present, the most authoritative FAO/WHO/UNU expert committee recommended casein in milk, ovalbumin in eggs and soybean protein in soybeans as the best quality protein. They are all digested and absorbed by the human body above 96%. Nutritionists advise people to increase their intake of high-quality protein. Everyone should eat at least 250 grams of high-quality milk and an egg every day, and eat soy products at least once a day. At present, many studies show that the nutritional value of soybean is higher than that of some animal foods. First of all, because it is at the bottom of the food chain, it contains less environmental toxins. Secondly, it contains W-3 fatty acids and lecithin, which is good for the heart. Leucine and isoleucine in soybean also have excellent effects on improving immunity.

Supplement foods containing vitamin A and vitamin C.

From a nutritional point of view, vitamin A can enhance the function of human epithelial cells and produce resistance to cold viruses. It can strengthen the mucosa of the throat and lungs and maintain their normal metabolism. If there is enough vitamin A in the body, the virus invading from the outside cannot spread through healthy mucous membranes. The effect of vitamins in immunity is mainly that substances formed by oxidation in the body can kill viral diseases.

The human body's demand for vitamin A is 2000 international units. Dark green vegetables and carrots are the best sources of vitamin A.

Vitamin C is abundant in fresh fruits and some vegetables, especially cabbage, tomato, pepper, jujube and Rosa roxburghii. In particular, the tissues and cells of jujube and Rosa roxburghii contain a lot of bioflavonoids, which can protect vitamin C from oxidative damage.

Workers who go out for a long time, students at school, and elderly people with poor digestion and absorption function, take one vitamin A pill orally every day, and take vitamin C orally twice a day, each time 100mg, which has a good effect on improving immunity.

Eat more wild mushrooms.

Wild mushrooms, which are popular in Asia, can be seen everywhere in markets and restaurants in Europe and America recently. Some wild mushrooms, such as boletus, Flammulina velutipes, Pleurotus ostreatus, Lentinus edodes, not only taste very good, but also are of great benefit to human health, which can enhance human immune function and prevent cancer.

When eating wild mushrooms, the best way is to cook chicken soup with local chicken. Dissolving the effective components in mushrooms in soup can improve the absorption rate of human body. Chicken soup itself can also improve the immunity of respiratory system, which can be described as killing two birds with one stone.

Improve immunity reasonably and have an effective diet.

How complex the immune system and immune function are, and how to form and strengthen immunity is a great achievement. In the face of sudden infection and mutated virus, I hope to improve my "combat effectiveness" with the help of some foods, health products, medicines, or folk remedies and secret recipes. This kind of self-help method of "grinding a gun at the last minute" or "mending after the sheep is dead" can't be said to be ineffective, but it often gets twice the result with half the effort, and sometimes even backfires.

Improving immunity is a natural, continuous and lasting process, not a compulsory, intermittent and expedient process. This process should run through a person's life.

Immunity should be "reasonable":

The human body needs "reasonable" immunity: neither "low" nor "vigorous". A large number of scientific studies show that too weak or too strong immunity is harmful to human body.

The change of human immunity is the result of the interaction between "in vivo" and "in vitro". With the help of a set of extremely complex and powerful "procedures and reactions", the human body effectively controls the regulation of immunity. Some people hope to participate in or change this internal regulatory system and process through external intervention, including food, drugs, lifestyle, etc., so as to improve their immune function to some extent and resist foreign aggression. Undoubtedly, the starting point is good, but the arduousness and complexity of the process itself are often beyond people's imagination, and a lot of "inside information" is still unknown, so modern technology is not enough to safely and effectively grasp the occurrence, development and outcome of this process. Therefore, some people vividly call it a "double-edged sword". So, people can't help asking this question:

How can we improve immunity safely, effectively and reasonably?

It is safest to improve immunity and eat reasonably. Comparatively speaking, a reasonable diet is safer than other means in improving immunity.

What is a "reasonable diet"?

Many people still have misunderstandings. Such as that "high-grade, exquisite food must be nutritious", "eating more fish and meat must be scientific" and so on. In fact, a certain food or a certain kind of food has its own nutritional components and biological characteristics, and it is impossible to fully meet all the nutritional needs of the human body. Any monotonous diet pattern or bad partial eclipse habit will lead to partial overnutrition and partial undernutrition in the body, leading to nutritional imbalance in the body. One of the adverse consequences of this imbalance is the decline of immunity. Therefore, for many people, the premise of improving immunity is to establish the concept of "balanced diet" and use this concept to guide daily eating behavior.

What is a "balanced diet"?

Simply put, a balanced diet can be summarized as "comprehensive, balanced and moderate" six concepts, including six principles: ① proper deployment; 2 varieties; ③ The proportion of thermogenic nutrients (protein, fat and carbohydrate) is reasonable; ④ Coordination between non-thermogenic nutrients and thermogenic nutrients; ⑤ Coordination between inorganic salts; ⑥ Nutritional components are coordinated with each other. It is to make the proportion of various nutrients contained in food appropriate, so that a sufficient number of various foods are in a relatively balanced state and avoid the adverse consequences of overnutrition or undernutrition.

Vitamins play an important role:

Studies have shown that vitamins, especially vitamin C, have a certain effect on improving and maintaining immunity. The main sources of vitamin C are fresh vegetables and fruits. Eating half a catty of green leafy vegetables and two or three fruits every day, especially sweet oranges, wild berries and kiwis, or drinking two glasses of fresh orange juice is good for vitamin C supplementation.

In addition, don't ignore other important vitamins and their main sources:

Vitamin A: animal liver, egg yolk, cod liver oil, tomato, carrot, sweet potato, etc.

Vitamin D: sufficient light, cod liver oil, egg yolk, milk, etc.

Vitamin e: vegetable oil;

Vitamin B 1: coarse grains, beans, peanuts, lean meat, viscera, dry yeast, etc.

Vitamin B2: egg yolk, river crab, eel, Tricholoma, laver, etc.

Folic acid: animal liver, fruits, vegetables, wheat bran, etc.

Vitamin B 12: meat, milk and animal viscera.

Theoretically speaking, if our diet can achieve a balanced nutrition, then all kinds of vitamins needed every day will not be lacking. However, the actual situation is often not so ideal: the loss of food during storage, processing and cooking and people's different degrees of partial eclipse lead to unbalanced vitamin intake. Therefore, on the basis of a balanced diet, it is necessary to scientifically supplement multivitamin preparations to improve immunity.

Garlic-a natural broad-spectrum antibiotic;

Garlic contains "allicin" with strong bactericidal effect. Studies have shown that a certain dose of allicin can kill dysentery bacilli, Escherichia coli, typhoid bacilli, Vibrio cholerae and Salmonella in the intestine, and can also kill or inhibit tuberculosis bacilli, diphtheria bacilli, staphylococci in the respiratory tract and mold on the skin. Therefore, garlic is called "natural broad-spectrum antibiotic".

Drinking green tea often has great benefits:

Recently, many people mentioned green tea. Indeed, there are many benefits of green tea, which can be roughly summarized as follows:

(1) Green tea contains a considerable amount of antioxidant flavonoids and catechins, which can effectively scavenge free radicals produced in the body and have certain antioxidant and anti-aging effects.

(2) Catechins contained in green tea have a certain inhibitory effect on human pathogenic bacteria.

(3) Green tea may be effective in preventing some cancers. But it needs to be confirmed.

(4) Catechins contained in green tea may also reduce blood cholesterol and low-density lipoprotein cholesterol, so green tea is also regarded as a blood lipid regulator.

An onion a day has many advantages:

Onion contains a large number of plant fungicides, which have strong bactericidal ability and can kill and inhibit Staphylococcus aureus, Streptococcus, diphtheria, Shigella, tuberculosis, Escherichia coli and other germs. Scientific experiments show that if you chew raw onions for 3 minutes, you can kill all the bacteria in your mouth.

Selenium, a trace element contained in onion, is a strong antioxidant, which has anti-cancer, anti-cancer and anti-aging effects. In addition, onion also contains a chemical called "yellow oak", which is one of the strongest natural anticancer substances known at present. It can not only prevent the appearance of cancer cells, but also contain them when they begin to grow and spread. Scientific research also found that onions have special effects on gastric cancer. People who often eat onions have a lower incidence of gastric cancer than those who eat little or no onions. An American medical report pointed out: "Eating an onion every day is good for your health." It can be seen that onion has high nutritional value and dietotherapy value.
