In March 2022, the epidemic situation in Shandong, Jilin, Shanghai and other regions counterattacked. Since most people have been vaccinated with three doses of the new crown vaccine in the whole process, the infected people are mild Symptomatic or asymptomatic are predominant, and severe cases are rare.
However, with the rapid spread of the epidemic, the epidemic situation in some areas is very serious. There are several high-frequency words: protection, isolation, immunity.
“Immunity is called the best doctor”, mentioning Professor Zhang Wenhong, everyone must be familiar with it. The prevention and control of the epidemic has made a lot of contributions.
Why are some people easily infected while others are safe in the face of the new crown epidemic? Well, most of it has something to do with autoimmunity.
First of all, what is immunity?
Immunity refers to the body’s ability to recognize and eliminate foreign bodies and to deal with aging, damaged, dead, degenerated own cells, as well as to recognize and process the body’s own cells The ability of mutant cells and viruses to infect cells.
It is the defense mechanism of the human body and has the ability to maintain the stability of the internal environment, which is a normal physiological response. After research, it is found that immune function decline is one of the most important reasons for aging, and this change is quietly, slowly and continuously.
Immunity and the immune system
< span>Immunity is directly related to the immune system. When the immune system is normal and stable, the immunity will be high. When the immune system is disordered, the immunity will be low.
The human immune system is composed of immune organs, immune cells and immune molecules, as follows: span>
1. Immune organs: mainly include lymph nodes, tonsils, appendix, spleen, bone marrow, etc.;< /span>
2. Immune cells: They are mainly developed and produced in immune organs. B lymphocytes and T lymphocytes are the most important in the body. two types of immune cells.
B lymphocytes will eventually differentiate into plasma cells, which can produce a variety of antibodies, and T lymphocytes can recognize and Destroys pathogen-infected cells, or mutated cells, and maintains self-tolerance and prevents immune overreaction from damaging the body;
< span>3. Immune molecules: they are synthesized and secreted by immune cells and can participate in the body’s immune response, including cytokines such as complement, immunoglobulin, interferon, and interleukin.
What are the symptoms of low immunity?
There are actually many manifestations of low immunity, and many of them are often not very specific. Here, the doctor will share with you some of the most common ones. Performance.
1. The feeling of fatigue is strong, and there is no way to completely relieve it after rest: < /strong>For healthy and normal people, if they are too tired, they can often recover well after rest.
But for people with weakened immune systems, may be relieved after rest, However, I soon re-entered a state of fatigue. Even if I didn’t do heavy work, tired work, or stayed up late, I always felt very tired.
2. Frequent colds: The higher the frequency of colds, the lower the immunity of the body. People catch a cold when the weather cools down a little or when the cold wind blows. Every time influenza comes, they cannot escape, and they tend to be sick for a long time and recover slowly.
3. The wound is easily infected and the recovery is slow: After a certain part of the body is accidentally scratched, the wound heals very slowly, and there are often redness, swelling and even suppuration. These are often typical manifestations of low immunity.
4. Mouth ulcers are not easy to heal: People with low immunity are prone to repeated oral ulcers, and the ulcers are difficult to heal, and the effect of medication is not ideal.
5. Gastrointestinal diseases are prone to occur: Some people are Usually only eat a small amount of spicy or greasy food, there will be severe gastrointestinal discomfort, vomiting and diarrhea.
The appearance of this situation also shows that the protective function of the gastrointestinal tract is inflamed, which is due to the body’s immunity caused by low.
Is diet related to immunity?
Among various environmental factors, the impact of a healthy diet on immunity cannot be ignored. A well-structured diet will enhance immunity and prevent illness; unhealthy eating habits will directly affect the body’s immune system, making the body’s immune system low and susceptible to disease.
Different foods have different effects on immunity. Some nutrients in food can stimulate the immune system and strengthen the body’s immunity. Once these important nutrients are deficient, the body’s immune function will be severely affected. Let’s look at the relationship between food and immunity from a nutritional point of view.
The main force of immunity: protein is essential, and the function of the human immune system mainly depends on protein. One of the main components of white blood cells and immune system antibodies is protein.
The second is vitamins, which are the best companions for protein. The relationship between vitamins and immunity is closely linked. Vitamin C stimulates the body to produce interferon to destroy viruses, reduce the binding of white blood cells to viruses, and maintain the number of white blood cells.
Zhang Wenhong: The most effective drug is immunity! During the war epidemic, eat 6 more things to fight the virus efficiently
1, orange food
Orange-yellow foods can be converted into vitamin A in the body, such as carrots, pumpkins, and corn, which are rich in carotene. If the vitamin A in the body is insufficient, the resistance of the respiratory mucosa is correspondingly reduced, and it is easy to get infectious diseases.
Garlic is not only delicious, but it also has health benefits, such as lowering blood pressure and reducing the risk of heart disease. Garlic’s immune-boosting properties are due to its high concentration of sulfur-containing compounds that can help fight some infections.
Research shows that participants who took garlic supplements were less likely to develop a cold. And those who got infected recovered faster than those who took a placebo. It is recommended to eat two to three garlic cloves a day.
While sun exposure is the best source of vitamin D, some foods, including mushrooms, can also provide vitamin D.
A review of mushrooms as a source of vitamin D found that “sunshine vitamin” may help enhance calcium absorption , which is good for bone health and may also protect against some cancers and respiratory diseases.
Many people like to make tea with lemon , because lemons contain a lot of vitamin C, and also contain some trace elements.
Lemon is an acidic fruit. From the perspective of traditional Chinese medicine, its sour taste can help the human body to astringe and solidify body fluids. To the effect of clearing heat and detoxifying, drinking more lemon water at ordinary times can also prevent the occurrence of colds.
Yogurt may seem like it has nothing to do with colds, but yogurt can also prevent colds.
Some expert studies have shown that yogurt contains a variety of active substances such as probiotics, as well as a variety of minerals and trace amounts Elements can enhance the body’s metabolism and help to expel toxins.
However, regular consumption of yogurt is not only good for the gastrointestinal tract, but also fights colds and enhances immunity.
The protein content of chicken is about 20%, and it contains a variety of amino acids that are beneficial to human digestion, as well as minerals such as copper, iron, zinc, as well as B vitamins, lipids Great source of soluble vitamins.
In addition, chicken is rich in phospholipids, which play an important role in human development. #Aile Health Guide#
