“Improving immunity can keep away from diseases!” This is the reporter’s first impression of immunity when investigating most people around him. While modern people pay more attention to their own health, many businesses have seen people’s mentality and vigorously promoted products with the effect of “enhancing immunity”. Royal jelly, cod liver oil, amino acids… As long as various health products are linked to immunity, their value can be doubled.
the brand of immunity will sell well.
Many pharmacies and supermarkets have found that almost all supermarkets sell health products that “improve immunity”, and the health products in pharmacies even have special counters. A large drug supermarket has also specially opened shelves for “enhancing immunity”. The reporter roughly counted the shelves. The shelves more than one meter high and two meters wide were filled with more than 20 kinds of health care products with the words “enhancing immunity”. On many packaging boxes, these five words are larger than the product name. When the reporter asked the clerk what was the best gift for the elderly, the clerk said without hesitation: “health care products sell best, which can improve resistance and prevent illness.”
At present, 1375 kinds of domestic health food with the function of “improving immunity” have been approved. Propolis, protein powder and amino acid oral liquid account for the majority. Although their ingredients are different, they all emphasize the effect of “enhancing immunity”.
What is even more surprising is that many ordinary foods have also caught the fast train of immunity. Xiao He, a salesperson of a large supermarket, told the reporter that some manufacturers would play a fringing ball when placing goods, such as a kind of bagged ordinary red dates, which would sell particularly well as long as they were pasted with the words “improve immunity”. But in fact, when you look carefully at the description of the packaging bag, you don’t find this so-called health care effect.
Four Misunderstandings: misinterpreting immunity
The body is like a battlefield. Invisible “war” happens in the body every day, but most of the time you don’t know it. This is because the “human army” is in absolute superiority. However, when your body temperature rises, your whole body aches, your nose is full of tears, and your pain is unbearable, it indicates that there are some problems with the “army” in your body, and enemies such as diseases will take advantage of it to enter, causing you to lose strength.
This “army” hidden in the human body is the immune system, which includes bone marrow, thymus, spleen, lymph nodes, tonsils and other immune organs. Under normal circumstances, the immune system of the human body will be consistent with the outside world, fight bravely to kill enemies, gain war experience, and protect the “peace” in our body day and night. But sometimes, the autoimmune system also has internal problems: Investigators sometimes neglect their duties, rebels appear in the army, and “infighting” occurs, which makes people lose.
Immunity, the “army”, is the body’s own defense mechanism. Experts say that many people do not understand this mechanism, and there are mainly four major misunderstandings.
Myth 1. The stronger the immunity, the better. Hong Zhaoguang said that immunity is like blood pressure and blood sugar. If it is low, it is not a good thing. It is easy to cause bacterial and viral infections, but if it is too high, it is also a disease and harmful to the human body. If the immune response is too strong and destructive, it is also easy to suffer from autoimmune diseases such as lupus erythematosus and rheumatoid arthritis. Therefore, good immunity is in a balanced state, and it needs to have good self-regulation ability.
Myth 2. Immunity is resistance. Resistance includes immunity, rejection, repair (healing and regeneration) and many other abilities, and immunity is only one of them. In short, the scope of resistance is larger. Therefore, the words of drugstore salesmen that “enhancing immunity can improve resistance” are not completely correct.
Myth 3. The elderly and sub-health people need to take medicine or health products to enhance their immunity. If it is not necessary, drug abuse should be resolutely opposed, because drugs interfere with the immune system the most. In particular, we should oppose the practice of taking hormone drugs at will and abusing immunoglobulins. For some health products that claim to enhance immune function, there is no measurement standard, no evidence-based medicine support, and no need to take them.
Myth 4. The immune system of infants and young children is underdeveloped and needs special protection in daily life. Under the excessive protection of parents, children’s immune system becomes weak and vulnerable, which is very unfavorable to their growth. Therefore, the army in the body should refuse to “treat others with dignity”, and only by constant stimulation can it improve its combat effectiveness.
normal people do not need to enhance immunity
Usually, everyone’s immune system is in a state of balance. Only when children have repeated colds, pneumonia or diarrhea, and adults have unexplained rashes, fever that persists for a long time, and joint swelling and pain, they need to go to the hospital for examination. Experts remind that we should pay attention to the following points in our daily life:
Children don’t have to be too clean. The immune system has a “good memory” and will form an immune memory of the infectious pathogen. If it encounters the same pathogen next time, it can be eliminated quickly. If the environment around the child is too clean, the chance of infection and antibody production will be reduced, and the resistance will be weakened instead.
Although the immune system of young and middle-aged people is very strong, it is easy to be disturbed by bad emotions and pressure. Once you find yourself feeling unwell, you should start with the most basic sleep and diet. A good sleep can increase white blood cells in the body and enhance the detoxification function of the liver, so as to eliminate invading bacteria and viruses.
In addition, maintaining an optimistic mood can help improve immunity, while stress can suppress the immune system, making the human body vulnerable to colds and other diseases.
For the elderly, it is better to eat some health products that increase their resistance than to supplement all kinds of nutrition in a balanced way, because nutrition is the foundation of immunity. Drinking one egg and 250ml of milk every day can ensure the intake of high-quality protein, including animal food and bean products. Eat more fresh green leafy vegetables and fruits, which are rich in trace elements, vitamins and dietary fiber. In addition, proper exercise is beneficial to promote blood circulation throughout the body, delay the aging of body tissues and the attenuation of immune system functions.
