Myth 1, over-protective children over-dressing, closed doors. In fact, parents should give their children a little cold, to give children cold exercise, physical fitness will enhance some, as the saying goes: “autumn freeze spring cover” . Too much attention to cleanliness, the child is nurturing, do not get exercise, immunity is not well stimulated, resistance will be weakened. Allergic diseases are on the rise every year because children are now in an overly clean environment. Exposure to enough germs is what makes their immune system less vulnerable. Too much preference is given to high-protein fish and fine grains and no coarse grains and vegetables. In fact, coarse grains and vegetables can provide vitamins, fiber and other nutrients that are lacking in fine grains. Giving children winter worm, sea cucumber and bird’s nest porridge is actually unnecessary. It is not good for parents to give their children too much and too good food, which will affect the normal functioning of the spleen and stomach. As the saying goes: “For a child to be safe, he must be three parts hungry and cold.” The second misconception is that the child is sick is low immunity think that the child is sick is low immunity, in fact, it is not. The immunity of children is a gradual development process. A certain degree of fever can accelerate the metabolism of the body, the immune function is active, antibody production increases, the liver detoxification function is enhanced, after this process, the child’s immunity, the stress capacity of germs will be improved. For infants and children who do not have immunodeficiency, what appears to be “low immune function” is often an “illusion”, mainly because the child’s “immune memory” has not yet been established, and there are too many opportunities to be exposed to infectious agents in child care facilities or other environments. A truly immunocompromised child is one who has a primary or secondary immunodeficiency disease and must receive regular treatment. Misconception 3, playing gammaglobulin Playing gammaglobulin to enhance physical fitness, wrong! Gammaglobulin contains various antibodies of human serum, which can be stored in the body for 2~3 weeks and can enhance the immunity of the body. It is used clinically for the treatment of certain diseases, such as: treatment of immunodeficiency diseases, such as congenital c globular deficiency, variable immunodeficiency, and cellular deficiency with abnormal immunoglobulin synthesis; treatment of massive burns, severe traumatic infections, Kawasaki disease, and sepsis or endotoxemia. From a preventive point of view, gammaglobulin does prevent some viral infections and enhance resistance. For example, people who have not had measles or have not used measles vaccine can get passive immunity without measles or reduce symptoms within 6 days after contact with a measles patient, and can prevent 3 to 8 weeks. For susceptible children who have not taken live polio vaccine pills, propecia can also prevent or reduce the onset of the disease when administered within 7 days after contact with a patient with the disease. However, after all, gammaglobulin is a blood product, which may cause allergic reactions and other adverse reactions, and once the blood source is contaminated, the patient has a great chance of contracting infectious hepatitis and AIDS after injection, and in recent years, clinical cases of infection due to injection of unclean blood products have been found one after another, so gammaglobulin is not used freely for immunoprophylaxis. The foreign gammaglobulin will be consumed in about 2 months, and it will also inhibit its own ability to synthesize gammaglobulin. Gammaglobulin is not a nutritional health drug to prevent all diseases and enhance physical fitness, so do not use it blindly. Myth #4: Rely on drugs to improve immunity Clinically, although some immune drugs have certain immunomodulatory capabilities, such as thymidine, interferon, etc., these drugs are only suitable for people with low immune function, such as patients with immunodeficiency diseases, chronic infectious diseases or tumors. For children with normal immune function, it is ineffective to take immune boosters because the body maintains stable immune function. Can I give my child protein powder to boost immunity? A: Protein powders do not boost immunity in children and may be harmful. Firstly, the protein purity of protein powder is too high, and it is easy to increase the burden on the liver and kidneys when consumed; secondly, excessive protein intake during infancy and early childhood can cause an increase in the differentiation of fat cells in the body, which is the basis for obesity in adulthood. Many health products on the market boast of their immunity-enhancing functions are not credible. The stronger the immunity, the better the human immune system will maintain a dynamic balance through various mechanisms, low is not good, too strong is not good, too strong immune function will lead to autoimmune disease, when the immune system will attack the normal human tissue will cause a disease called autoimmune, such as rheumatoid arthritis, lupus erythematosus, etc..
