What are the foods that improve human immunity?

What foods can improve immunity?

first, what is immunity?

Immunity is the ability of the immune system to protect our health. Low immunity is the internal root cause of people's illness.

second, what is immunity?

Immunization means "free from plague". Refers to the body's resistance to reinfection of infectious agents (that is, plague, such as smallpox, typhoid fever, diphtheria, etc.). The strength of resistance can be expressed by immunity. The so-called infectious factors refer to pathogenic microorganisms such as bacteria, viruses and molds.

Third, the relationship between immunity and human health

People's health is closely related to immunity. The immune system is like our national security department, shouldering the tasks of resisting foreign invasion, eliminating aging and cancerous cells in the body and helping to repair damaged organs. Only when the immune system is healthy can it better provide strong immunity. If the immune system is not healthy, immunity will inevitably be hurt.

fourth, how is the human immune system formed?

The human immune system includes: immune organs (central immune organs and peripheral immune organs), immune cells (T, B and Nk cells) and immunocompetent molecules (antibodies, complements and cytokines).

V. Functions of human immune system

Specifically, the immune system has three major functions. (1), immune defense: the body's immune protection against foreign antigens, or anti-infection immunity, can remove viruses, bacteria and other pathogenic microorganisms. (2) Immune stability: Under normal circumstances, the body may often remove damaged or aging cells to maintain the relative stability of the body. (3), immune surveillance.

sixth, food to improve immunity?

1. Traditional health preserving theory holds that five grains, five animals, five fruits and five vegetables nourish life.

2. Modern medicine believes that there are six categories and 42 kinds of nutrients constitute the living organism:

(1), the manna and water of life

(2), and the basic substance of life-protein: 9 kinds of essential amino acids: isoleucine, leucine, lysine, methionine, threonine, phenylalanine, tryptophan, methionine and histidine.

(3), mysterious minerals, 15 minerals and trace elements).

minerals are divided into macroelements and microelements.

A, a constant element, refers to various elements that cannot be naturally synthesized in the human body and must be ingested from the outside, and the content in the human body is greater than .1% of the human body weight. 7 kinds of calcium, phosphorus, sodium, potassium, chlorine, magnesium and sulfur.

B, a trace element with a content less than .1%. Iron, zinc, iodine, selenium, molybdenum, copper, cobalt, etc.

(4), magic vitamins, (14 kinds of micro-biotics)

A, D, E, K, B1, B2, B6, B12, vitamin C, etc.

(5), the building blocks of life, (two unsaturated fatty acids), linoleic acid and linolenic acid.

(6), energy-supplying substances of life, (carbohydrate), sugar, starch.

To improve human immunity, we must achieve balanced nutrition, not partial eclipse or picky eaters. In addition to the comprehensive intake of the above 42 nutrients, the human immunity will naturally be improved in an all-round way.

to improve human immunity, the first thing most people think of is to eat something.

However, there are many people around us who are not short of nutrition, but are anaemic and sub-healthy. When you feel bad, the first thing you think of is something to eat. Traditional medicine in China is the supplement. Supplementing qi, blood, yin, yang and kidney, and now a Bufei pill is also given.

However, as far as I know, most drugs that tonify qi and yang are drugs that tonify kidney, and most drugs that tonify kidney are drugs that enhance male reproductive ability. Most of nourishing yin leads to obesity.

In 2, it was discovered that many women were given milk by Chinese medicine for lactagogue, but their children ate milk with Chinese medicine, and their fontanels closed early!

Even some pregnant women took tonic medicine, and their children were born with teeth, and the seams of the skull were calcified early, so they could not do deformation exercise. As a result, the skull was too big to give birth naturally, so they had to have a laparotomy!

To improve immunity and maintain a normal body shape, it is best not to make up for it. In addition to eating our traditional diet in China, such as rice, eggs and meat, it is important to strengthen exercise and get enough oxygen.

Many people have low immunity because of poor sleep environment and lack of oxygen during sleep.

For example, a newborn, just born, is in a sub-healthy state.

if you start after birth, eat enough and sleep well, whether you eat breast milk or milk, eating enough is the most important thing.

and I feel that eating milk makes me sleep better. But many people, breast milk is not good, but in order to let their children eat breast milk, they would rather let their children starve, thinking that through sucking reflex, milk will gradually increase.

As a result, the child was hungry for half a month. Because he was hungry and didn't sleep well, his immunity dropped significantly. The decline of immunity limits the development of the nervous system, and some may have been sub-healthy! Natural immunity cannot be enhanced. Some of them may be better because of conditioning. Although their health has improved and their immunity has been enhanced, the delay in the development of the nervous system is irreparable.

Some newborns also have poor sleep because of the bad air in their home environment.

So, the key issues are

firstly, improving sleep quality. Make sure to inhale enough oxygen during sleep.

Second, strengthen physical exercise and aerobic exercise. Since being "trapped" at home by COVID-19, everyone began to pay attention to how to improve immunity in order to deal with some sudden diseases. The subject asked about the foods that can improve human immunity, but in fact, immunity is not only affected by diet, bad mood and bad lifestyle will reduce immunity, so I will tell you how to improve immunity from three aspects: diet, mood and lifestyle.

What foods can improve human immunity

1. Foods rich in carotene: carrots, spinach, Chinese cabbage, cauliflower, pumpkin, eggplant, peppers, mangoes, oranges, bananas, etc.

2. Foods rich in vitamin E: walnuts, peanuts, sesame seeds, pine nuts, mulberries, pumpkins, bean products, etc.

3. Foods rich in vitamin C: cauliflower, tomato, strawberry, mango, orange, kiwi fruit, grape, watermelon, etc.

4. Foods rich in vitamin B6: white meat, beans and vegetables.

Have you found that all the common diets mentioned above can improve human immunity? That is to say, as long as you are not picky eaters and partial eclipse in your daily diet, you can achieve the effect of improving human immunity, but at the same time, you should also eat less fried foods, less high-calorie foods such as hamburgers and French fries, eat on time, eat more fresh fruits and vegetables, and not overeat.

In addition, it should be noted that the choice of the above diets should vary from person to person. If you have taboos about certain diets and can't eat them, you should choose them flexibly according to your own situation. Mood is also a factor that affects immunity

Being depressed and unhappy for a long time will affect one's immunity, and many diseases are related to bad emotions, so we must maintain an optimistic attitude in our daily life. Bad lifestyle is also a factor affecting immunity

Staying up late, overworking, sitting for a long time, smoking and drinking will all affect immunity. In order to improve immunity, we should maintain a healthy lifestyle, such as keeping enough sleep, working and sleeping regularly, exercising moderately and quitting smoking and limiting alcohol.

What foods can enhance immunity

1 Eating foods rich in nucleic acids and protein, such as soybeans, lean meat, fish and shrimp, and egg meat are mainly divided into poultry meat and livestock meat. Poultry meat contains more protein but less fat, fish meat is easier to digest than livestock meat, and protein content is more, especially marine fish, and selenium content is more, which can help improve immunity.

2 fresh dark fruits and vegetables are foods rich in vitamin C. Vitamin C is a trace element that the human body cannot synthesize, so it needs to be converted into vitamin C through food intake. This kind of vitamins mainly play a role in promoting the synthesis of human immune proteins, thus enhancing human immunity, so it is necessary to increase vitamin C food intake in order to improve immunity.

therefore, eating more fruits with high vitamin c content, such as kiwi fruit, cherry, etc., can increase the absorption and utilization of calcium for vitamin d in carrots, spinach and tomatoes, and organic acids such as malic acid and citric acid in fruits can promote the secretion of digestive juice, which is also a food to improve immunity.

3. Nut Yogurt Nuts are also rich in protein and fat, and melon seeds are also high in calcium, iron and zinc. Many yogurts are added with probiotics, which can help intestinal digestion and balance intestinal flora, and are also beneficial to enhancing immunity.

Staying on cereals, mushrooms and appropriate miscellaneous grains to ensure body calories, dietary fiber and vitamins can promote personal immunity. Appropriate exercise and adequate rest and sleep can better improve immune behavior.

There are many protein fungi in foods that can improve immunity. Staying up late at ordinary times and being optimistic will improve your immunity. Can you strengthen your immunity by food?

Immunity is "an ability of the body", which is basically "the ability of the body to resist pathogens". Any kind of food does not have the function of "activating and strengthening" immunity. To protect immunity from "damage" and maintain its strong immune system, it is necessary to be "balanced and comprehensive" in diet. Please don't exaggerate any kind of food. Rumor has it that "eating sea cucumber can enhance immunity" and "eating chinese forest frog can strengthen resistance" and other "food efficacy" remarks can't be realized at all. Immunity doesn't need to be improved deliberately. What we should do at this special stage is to "protect our own strong immunity". Talk about "immune principle":

Everyone's body has an "immune system", and the immunity of the body is mainly composed of "immune cells, skin and mucous membranes of the body, immune organs and tissues, and immune active substances". Their existence creates a "complete and complex immune system" of our body, and their function in the body is to "resist the invasion of harmful substances such as external pathogenic microorganisms". When our body is working normally, the immune system can identify and remove "abnormal cells" in the body at any time, such as tumor cells; In addition, it can remove aging cells, damaged cells and dead cells in the body in time.

This passage helps you to correct your view on immunity. For a normal person, his immunity is normal. In fact, he can completely defeat those pathogenic microorganisms that invade his body, and you don't need to do something extra (eat some food, take some medicine, etc.) to deliberately improve his immunity. In other words, we don't need to do something to improve our immunity in our life, and this role doesn't exist, and it's just a waste of money. The most important thing you should do is not to consume your strong immunity too much and refuse those "bad habits" that reduce immunity. What can I do to ensure my strong immunity?

A good meal and a comprehensive and balanced diet can provide protein, energy and other substances to the "tens of billions of immune cells" produced by the body every day. It is recommended to eat more than 14 kinds of food every day.

Only by combining work and rest can you be healthier; Adequate sleep contributes to the formation of "strong immunity". Many people like to stay up late, but staying up late will consume your muscle tissue and increase the risk of obesity, which will also destroy the immune system and reduce immunity.

Therefore, "good sleep" is the basic health point, and adults should sleep for 7-9 hours every day.

Please note that exercise can speed up the circulation of immune cells-white blood cells, thus helping the body to prevent the invasion of harmful substances from outside. Therefore, move more when you have nothing to do, and move every day; Doing housework can promote calorie metabolism, and jogging and brisk walking can also accelerate the body's calorie metabolism, with 3-6 minutes of exercise every day.

in addition to these, we should also pay attention not to "abuse drugs indiscriminately", refuse drug dependence, and don't always overuse drugs. Our own immune system is actually very strong.

Immunity is a vague concept. To be precise, it should be called immune system function. It is a sophisticated and complex network composed of immune cells such as lymphocytes, immune tissues and organs such as thymus and spleen, and immune molecules such as antibodies and complements. Under normal circumstances, members of this network cooperate with each other to fight against harmful foreign bodies such as pathogenic microorganisms such as bacteria and viruses. The strength of human immunity is related to factors such as age, heredity, living environment, living habits, diseases and drugs. Decreased or disordered immunity can induce many diseases, while too strong immunity will make the immune system mistakenly attack normal cells of human body and induce autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis.

There are many foods or health products circulating on the Internet that can improve immunity, such as lactoferrin, protein powder, probiotics, bird's nest, etc., which have no scientific basis. Lactoferrin mainly exists in human immune cells and breast milk, and has a little relationship with immune function. However, the lactoferrin currently sold in the market mainly comes from milk, which is completely different from human lactoferrin. In addition, lactoferrin will be destroyed by digestive juice and lose its activity. Protein powder is a supplement to protein, which does not improve immunity. protein can be supplemented by diet. Excessive supplementation of protein can not be used by the body, which will turn into fat, lead to obesity and increase the burden on the kidneys. The main function of probiotics is to regulate the balance of intestinal flora. Studies have shown that specific physiological indexes can be changed by supplementing specific probiotics, but it has nothing to do with improving immunity. The main nutrients of bird's nest are protein, carbohydrates, water and trace minerals, which are necessary for human body, but have nothing to do with improving immunity.

In terms of diet, diversified diet and balanced nutrition are the only rules to improve immunity. First of all, protein is the material basis to maintain the immune function of the body. It is recommended to eat 12-2g lean meat, fish, poultry and eggs, 3g milk, and 25-35g soybeans and nuts every day, which is helpful to improve immunity. Secondly, vitamin A and vitamin C can regulate and maintain the immune function of the body, appropriately increase the intake of food such as animal liver, carrots, spinach and pumpkins, and help to supplement vitamin A. It is recommended to eat 3-5g of vegetables every day.
