Low immunity is more painful. The usual manifestations are listlessness, insomnia, fatigue, repeated colds and easy to be infected ... and our health is particularly poor, which is basically caused by low immunity, so if we want to improve our health, we must first improve our immunity! However, improving immunity should not be rushed, and it needs to be recuperated slowly, so I recommend camel milk to you.

Camel milk is characterized by its rich linoleic acid and a large amount of zinc. Conjugated linoleic acid is one of the indispensable fatty acids for human beings and animals. It is a key nutrient, ubiquitous in any animal and determines the strength of immunity. It cannot be synthesized in humans and animals, and must be taken from food.

In the west, * * * conjugated linoleic acid is called "magic factor", which can not only improve human immunity, enhance human antioxidant capacity, promote growth and development, but also have a comprehensive benign regulation effect on human body.

Zinc is a component of many important enzymes in human body, and also a nutrient for the development of thymus, an immune organ. Only sufficient zinc can effectively ensure the development of thymus, differentiate T lymphocytes normally and promote cellular immune function. Zinc is of great significance to human immune system.

Moreover, the heavy chain antibody contained in camel milk is similar in structure to the antibody in breast milk, and the digestion and absorption rate is as high as 98%, so drinking camel milk can improve the immunity the fastest! If you want to improve your immunity, you can try drinking camel milk.

Of course, there are many other ways, such as eating more fruits and vegetables and enhancing immunity, and other diseases will stay away from us.

In daily life, it is very necessary for us to improve our immunity. When the body's immunity drops, which vitamin should we supplement most?

The answer is vitamin C.

What role does vitamin C have?

Vitamin C, also called L- ascorbic acid, is a water-soluble vitamin, which is rich in fruits and fresh vegetables.

Vitamin C mainly has the following four functions:

0 1 improve immunity.

At present, the most important function of vitamin C is to improve the body's immunity, which mainly plays a role in the three defense lines of the immune system.

First of all, the first line of defense of the immune system is the skin and mucous membrane, which can keep most bacteria and viruses out of the body. Vitamin C can help maintain the integrity of skin and mucous membranes.

Second, the second line of defense of the immune system is the bactericidal substances and phagocytes in body fluids. Phagocytosis can wrap up and kill pathogens such as bacteria. Vitamin C can promote the phagocytosis of phagocytes, and the phagocytic function of leukocytes depends on the level of vitamin C in plasma.

Finally, the third line of defense of the immune system includes humoral immunity and cellular immunity, and vitamin C can promote the differentiation and proliferation of lymphocytes. Promote the formation of antibodies; Improve the activity of natural killer cells, thus improving the recognition and killing ability of target cells; Relieve symptoms such as allergies and inflammation.

02 antioxidation

Vitamin C is a strong antioxidant, which can protect the activity of some enzymes in the body, scavenge free radicals, prevent lipid peroxidation and toxic effects of some chemicals, and protect the detoxification ability of the liver and the normal metabolism of cells.

Help synthesize collagen.

Vitamin C is very important for collagen biosynthesis. Ascorbic acid is an auxiliary factor of prolyl and lysyl hydroxylase, which is responsible for stabilizing and crosslinking collagen. Ascorbic acid can also directly stimulate collagen synthesis by activating and stabilizing procollagen mRNA (serine protease) transcription. Scurvy, which we often hear, is a classic physiological disease when the synthesis of vitamin C and collagen products is impaired.

04 detoxification

According to the report of Reference Intake of Dietary Nutrients for China Residents (Version 20 13) compiled by China Nutrition Society, vitamin C supplementation can not only enhance human immunity, enhance the phagocytosis of white blood cells, but also help drug absorption and promote detoxification of toxic substances and drugs.

How to effectively supplement vitamin C?

Since vitamin C is so important, how should I supplement it?

Generally speaking, most people can get enough vitamin C from their daily diet without extra vitamin C supplementation.

Eating more fruits and vegetables is the best way to supplement, because many fruits and vegetables are rich in vitamin C, and the intake of vegetables is relatively large. It is recommended to eat 300 or 500 grams of vegetables every day. If vitamin C is lost during cooking and frying, some vegetables can be fried quickly.

Pay attention to when eating fruits and vegetables:

1. Don't store vegetables and fruits for too long. Vitamin C is easily oxidized in the air, and the longer it is stored, the greater the loss of vitamin C. ..

2. When washing vegetables, wash them before cutting them. When soaking, enough is enough to avoid the loss of a large number of water-soluble vitamins caused by improper cleaning methods.

3. When cooking vegetables, be careful not to heat them too high or for too long, so as not to destroy vitamin C at high temperature.

What is the food with the highest vitamin C content?

When it comes to vitamin C, oranges and lemons are definitely the first foods we think of.

The vitamin C content of oranges is 33mg/ 100g.

The vitamin C content of lemon is 22 mg/100 g.

How to take vitamin C supplements?

In order to resist the epidemic, most people stay at home and the food supply is not sufficient. Many people even seldom go out to buy food, and some places can't even buy enough fruits and vegetables. Vitamin c is probably insufficient. Therefore, at this time, it is also beneficial to supplement vitamin C appropriately.

I'll go to the drugstore to buy vitamin C before it's too late!

Wait a minute, supplements are not eaten casually.

According to the reference intake of dietary nutrients for China residents, the recommended daily intake of vitamin C is 100 mg, the recommended intake for preventing non-communicable chronic diseases is 200 mg, and the maximum tolerable intake is 2000 mg.

No. 1

Appropriate supplement, not excessive.

Like many other nutrients, the content of vitamin C in the body is not as high as possible. Excessive vitamin C in the body, some people will have poisoning symptoms, such as diarrhea, rash, urinary calculi and so on. , and there are serious fatal risks.

No.2

Choose a cost-effective supplement.

There are many kinds of vitamin C on the market at different prices. In fact, there is not much difference between a bottle of vitamin C with more than 100 yuan and a bottle of vitamin C with two yuan, so you can choose a cost-effective one.

No.3

Effervescent tablets are not recommended.

The dosage of effervescent tablets may be relatively high. The usual dosage of effervescent tablets is about 500 mg or one gram. Long-term consumption of this dose will increase the risk of urinary calculi.

Secondly, effervescent tablets contain sodium bicarbonate, which will increase the intake of sodium invisibly, which may not be good for people's blood pressure and body metabolism.

No.4

Don't use vitamin C tablets instead of vegetables and fruits.

In fact, no supplement can replace the role of food. There are many other nutrients in food, which are also good for the body. Therefore, don't think that you don't have to eat vegetables and fruits after taking vitamin C tablets. Vitamin c tablets can only be used as a supplement when vegetables and fruits are insufficient.

I was allergic to pollen in my twenties, but I didn't understand it at that time. I always thought I had a cold.

I have been treating colds, and the situation is getting worse and worse. I have a runny nose, a stuffy nose and sneezing until I finally develop asthma.

After being reminded by my colleagues, I said, "You have a cold at this time of year, and the treatment is ineffective. Is it a seasonal allergy? " Diagnosed by the Allergy Department of Peking Union Medical College Hospital, she was allergic to pollen in summer and autumn, and was seriously allergic to humulus pollen, mites, indoor dust and cigarette smoke.

Every year, beginning of autumn starts to get sick, so he can't go to wild places where there are many weeds. It's fine during the day, but his condition is even worse at night. He can't lie down at all. When he lay down, his trachea was completely blocked, and then he began to cough violently. He had to move a small bench and sit outside to feel more comfortable. So I embarked on a long road of seeking medical treatment. ...

First of all, I read an advertisement in the newspaper that Prozac in the United States can resist oxidation and improve immunity. At that time, around 1992, a bottle of 200 yuan joined a member organization in order to buy cheaper medicine, and * * * took tens of thousands of yuan of medicine, but it didn't get better obviously.

Moreover, around 20 10, "Cordyceps sinensis" is highly praised by people, so I asked my friend to bring back two small bags from Tibet, costing several thousand dollars. I drink a piece of water every day and eat it at night.

Both methods cost a lot of money and have not seen much effect. I once went to the hospital for a physical examination and met a kind old doctor. When she knew that I had a serious pollen allergy, she suggested that I take vitamin C supplements, which can exceed the normal dose. Since then, I have been insisting on supplementing vitamin C. I feel that allergic symptoms are getting lighter and lighter, and the onset time is getting shorter and shorter. If you feel short of breath before going to bed at night, just spray two asthma sprays, which basically does not affect your sleep. Moreover, by eating vitamin C for a long time, there are unexpected gains and I feel that my skin is much whiter than before.

All in all, I just want to say, to improve immunity, just use ordinary vitamin C, and don't waste any more money! !

Hello, I'm a Chinese doctor, and I'm glad to answer this question for you.

Eight nutrients for improving immunity

1, protein

Amino acids produced by protein decomposition are important helpers of human immune system, which can resist the invasion of diseases and pathogens. If the intake is insufficient, the immunity of skin and mucosa will decrease.

Compared with plant proteins such as bean products, animal proteins such as red meat and milk have more comprehensive amino acids and higher nutritional value. Therefore, it is not recommended that everyone eat vegan.

2. vitamin a

Once vitamin A is lacking, it can cause keratinization of respiratory, digestive, urinary and reproductive epithelial cells, which is easy to be invaded by bacteria.

Foods rich in vitamin A include animal liver, carrots, mangoes, sweet potatoes and spinach.

3. Tocopherol

Vitamin E is an antioxidant in the body and can also improve the anti-infection ability. Foods rich in vitamin E include vegetable oil, nuts, beans and wheat germ.

4, vitamin C.

Vitamins have immune function because they are rich in interferon inducers.

Eat more foods rich in vitamin C. Vitamin C can reduce capillary permeability and make it a barrier to prevent viruses from entering human tissues and protect body organs.

Foods with high vitamin C content include green leafy vegetables, tomatoes, cauliflower, green peppers, oranges, strawberries, kiwifruit, watermelons and grapes.

5. Iron

Iron deficiency can lead to anemia and reduce anti-infection ability, especially for infants, pregnant women and nursing mothers. Eat red meat, animal blood, animal viscera and other foods rich in heme iron.

6. Zinc

Zinc is a component of more than 65,438+000 enzymes in human body, which plays an important role in the development of immune system and the maintenance of normal immune function. Shellfish seafood, red meat and animal offal are good sources of zinc.

7.selenium

Selenium exists in almost all immune cells, and selenium supplementation can obviously improve the immunity of the body. Animal liver, kidney and seafood are the main sources of selenium.

8. Edible fiber

Intestine is the largest immune organ of human body, and dietary fiber is beneficial to keep the intestine healthy. Coarse grains, sweet potatoes, celery, spinach, beans, mushrooms and fruits are all good sources of dietary fiber.

Hello, I'm glad to answer this question for you.

First of all, what is immunity? Immunity is the body's own defense mechanism, and it is the body's recognition and removal of any foreign body (such as virus, bacteria, etc.). ); The ability to deal with the aging, injury, death and degeneration of their own cells, as well as the ability to identify and deal with mutant cells and virus-infected cells in the body. Modern science believes that immunity is a physiological response of human body to recognize and reject "dissidents".

In fact, improving personal immunity can promote one's own functional health. Therefore, people who care about or care for their bodies will think about how to improve their immunity. First of all, to enhance immunity, you can eat the following foods: 1. Eating high-quality protein can enhance human immune function. High-quality protein, such as sea cucumber, milk, eggs, chicken and tofu, can enhance immunity. 2. Increase the number of deep-sea fish. Deep-sea fish such as salmon, tuna and saury are rich in unsaturated fatty acids and high-quality protein, which can enhance human immune function. 3, you can also eat more berries, such as strawberries, blueberries, etc., rich in anthocyanins and antioxidants, which can enhance human immune function. 4, you can eat foods such as olive oil, which is also rich in unsaturated fatty acids, regulating human blood lipid metabolism and enhancing immune function. In addition, individuals should maintain a healthy attitude, work and rest regularly, and be positive.

Exercise, let you have a perfect natural state of improving immunity.

A: Immunity comes from a good mood.

1, medical experts believe: "Being in a good mood is not as good as being healthy and nutritious."

2, a happy mood can quickly improve immunity and enhance self-healing ability.

3. People are happy.

Eat more shrimp, squid, eggs, increase protein, strengthen exercise, be strong, and increase immunity.

So do plants. When trees are weak, they are prone to insects and illness.

What do you often eat to improve your immunity? People are no strangers to immunity. We all know that low immunity is easy to get sick. Especially after the COVID-19 epidemic, people have realized the importance of normal immunity, because the decline of immunity can easily trigger novel coronavirus or influenza virus.

If human immunity is compared to a country, then immunity is like the army of this country, which can resist foreign invasion and drive the invading enemy out of the country. Human immunity has the same effect, except that the main enemies of human body are microorganisms such as bacteria, viruses and fungi, such as novel coronavirus, which caused the COVID-19 epidemic.

Immunity is exerted through the immune system, which consists of immune organs, immune cells and immunocompetent substances.

The immune organs mainly include thymus, spleen, tonsils, lymph nodes and bone marrow. Immune cells mainly include lymphocytes, neutrophils, platelets and mononuclear phagocytes.

Immunoactive substances mainly include antibodies, interferon and tumor necrosis factor.

When bacteria, viruses and other pathogenic microorganisms or toxic and harmful substances invade, the human immune system will respond quickly, identify, locate and kill these invading enemies, because the immune system can identify itself and the enemy, and will not accidentally injure itself while killing the enemy. In addition, the immune system, nervous system and endocrine system construct an immune-neuroendocrine network system to regulate the overall function and immune function of human body.

To sum up, we can't see the importance of immunity and immune system to human body. Declining immunity and excessive immunity will make people sick.

What do people with decreased immunity often eat to improve their immunity? For normal people, in terms of diet, we only need to pay attention to balanced nutrition, reasonable arrangement of meals and timing of three meals, so as not to be picky about food, partial eclipse, overeating or hungry, and appropriately limit the intake of high-calorie foods (fried foods) and high-fat foods (such as animal fat and lard). ) and foods with high cholesterol (such as egg yolk and crab yolk). ) to prevent overweight and obesity from causing new health problems. It is not enough to increase fresh vegetables, fruits, nuts, coarse grains or a certain amount of coarse grains rich in cellulose and vitamins. In addition to maintaining good eating habits, it is also necessary to establish and develop good living habits, such as going to bed early and getting up early, avoiding staying up late and overworking for a long time, paying attention to the combination of work and rest, maintaining a positive and optimistic attitude, and avoiding long-term contact with or intake of toxic and harmful substances. For example, it is necessary to avoid long-term heavy smoking and drinking, maintain an appropriate degree of smoking and drinking, and do not harm your health while enjoying yourself.

For people with low or weak resistance, if there is no taboo, it is necessary to increase the intake of high-calorie food, high-protein food or high-nutrient food, such as eating lean meat, chicken, fish and duck. Eggs, mutton, milk and beef are also good choices.

In medicine, there are thymosin and so on. Traditional Chinese medicines include jujube, cassia twig, tremella, ginseng, codonopsis pilosula, red ginseng, astragalus, donkey-hide gelatin, kudzuvine root, peach kernel, etc. These can improve immunity to a certain extent.

In fact, the world we live in is full of bacteria and viruses, but even if we are exposed to these bacteria and viruses every day, we will not get sick. That's because our bodies have strong immunity and can be protected from bacteria and viruses. But at the same time, we will also find that in the same bad environment, some people are easy to catch a cold and get sick, while others are not easy to catch a cold and get sick, which is caused by different personal resistances.

Therefore, we often say that we should pay attention to improving the body's immunity in our daily life, so that we can get sick less and have a strong body. So, what foods should we eat regularly to improve our immunity? Let's talk about this problem.

First of all, let's understand how our body's immunity resists the invasion of bacteria and viruses, so as to know the importance of immunity and how to enhance our body's immunity. In fact, for our body's immunity, we will establish three lines of defense to fight and destroy bacteria and viruses:

The first line of defense is our human skin and mucous membranes. This first line of defense can keep out most bacteria and viruses. For example, when our respiratory system inhales air, it will bring some natural bacteria and viruses into the lungs, but our throat mucosa and ciliated tissues of the lungs will isolate some bacteria and viruses, and these invading bacteria and viruses will be excreted through coughing and sneezing. And our intact skin also plays a role in isolating bacteria and viruses. Like a complete bark, it can resist the invasion of the outside world, and the trunk is well protected.

The second line of defense is the bactericidal substances and phagocytes in human body fluids. They can destroy invading bacteria and viruses from the first line of defense. Phagocytosis will kill these bacteria and viruses swallowed in packages through phagocytosis, while some bactericidal substances in body fluids will directly kill these invading bacteria and viruses.

The third line of defense is our body's humoral immunity and cellular immunity, including white blood cells, lymphocytes and some antibodies, which can completely kill some fish that have escaped the net and leave some specific antibodies, so that when bacteria and viruses invade again, they can be killed accurately at the first time.

In this way, the human body has three lines of defense against bacteria and viruses, that is, immunity, which is like a solid wall to protect us from bacteria and diseases. However, in our daily life, we often suffer from some changes in external environmental factors or personal factors, which leads to the decline of our body's immunity. At this time, we are easily invaded by bacteria and viruses and easily get sick. Therefore, we must always enhance the body's immunity and improve it through some diet or exercise.

I don't know if you still remember that when we have a cold and get sick, doctors often prescribe some vitamin C Yinqiao tablets or tell us to eat more foods rich in vitamin C. This is because vitamin C can enhance our body's immunity and prevent and fight colds.

So in our daily life, we can eat more foods rich in vitamin C, which can improve our immunity.

Why can vitamin C enhance our body's immunity? This is because vitamin C can not only help us maintain the integrity of skin and mucosa, but also enhance the chemotaxis and deformability of neutrophils and improve their bactericidal ability. In addition, vitamin C can also promote the production of lymphocytes, improve the body's ability to identify and kill highly pathogenic bacterial viruses, participate in the synthesis of immunoglobulin, increase the production of complement, and promote the production of interferon, thus inhibiting the proliferation of viruses.

Therefore, in our daily life, we can eat more fruits rich in vitamin C, such as oranges, oranges, grapes, apples and kiwis. In addition, Yupingfeng powder is also an effective prescription to improve the immunity of the body, but this prescription can only achieve better results under the guidance of Chinese medicine doctors.

Besides, we can also enhance the body's immunity through proper physical exercise. Life lies in exercise. We see that Academician Zhong Nanshan, who is over 80 years old, is so strong that proper physical exercise can exercise and enhance his immunity.

If you have any questions, you can leave a message in the comments section. Welcome to pay attention and forward. Thank you for your support! Comprehensive nutrition, no partial eclipse. Carbohydrate, protein, fat, vitamins, cellulose, trace elements and other substances needed by the human body. The key is to have a healthy stomach, a strong heart and a normal lung. At the same time, liver and kidney poisoning, spleen injury and pancreatic and intestinal damage cannot be allowed. Don't eat breakfast in the morning to cause bile concentration and congestion, and don't overeat or eat midnight snack at night to prevent polyps from forming in large intestine defecation. In addition, moderate exercise keeps qi and blood running and maintains the normal function of skeletal muscles and tendons. Of course, there should be a modern concept to treat alcohol, tobacco and sex. Immunity is an invisible guardian, and it is also strengthened in the above tangible actions.
