In reality, what people often refer to as "immunity" is essentially the same as the medical concept of "immunity."What factors influence immunity levels?Frankly, most of our body's immunity depends on genetic factors, but environmental factors also play a significant role, such as diet, sleep, exercise, and stress.Among these, diet has the most decisive influence. Nutritional factors play a very important role in maintaining normal immune function and health.However, children grow and develop rapidly, and their physical and mental health development is most important during this period.Therefore, adequate and appropriate nutrition is crucial for a child's immunity throughout their life.

In essence, when a baby is born, the immune system is already almost complete in function, and most importantly, they have immune antibodies from their mother, which can ensure their basic health.However, after 6 months, the immune antibodies from the mother gradually disappear, but their own immune system is not yet fully developed.At this time, due to the low level of immune proteinsin the body, their resistance to pathogens is also relatively low, so people may find that babies over 6 months old are easily prone to diarrhea and fever.This is because their immunity is relatively low at this stage.After babies are 3 years old, their immune system, digestive system, respiratory system, and other systems are basically well developed, and their resistance gradually increases. Naturally, they are less likely to catch colds.

However, children under 6 years old belong to the "physiological immune function deficiency" state in the medical sense.

This means that children under 6 years old must pay special attention to nutrition.Nutrients that are closely related to our body's immune function include proteins, vitamin A, vitamin C, vitamin E, iron, zinc, and selenium, etc. Since babies cannot choose food on their own, parents must pay attention to giving children food rich in these nutrients.Some parents may think that since immunity is mainly hereditary, our bodies are so healthy, children's bodies must also be very healthy.

Parents who think this way should be careful. If infants and young children have nutritional imbalances, whether it is deficiency or excess, it will interfere with the developing immune system and even change the expression of genetic genes.Not only will they constantly catch colds and minor illnesses when they are young, but they may also develop various immune diseases and metabolic syndrome, cardiovascular disease, diabetes, and other chronic inflammatory diseases in adulthood.Is this the result you want to see?Therefore, whether a child's nutrition is good or not is not only related to whether they are tall and intelligent, but also to their lifelong health.Whether it is lacking in calcium, zinc, iron, or vitamins A and D, it can lead to malnutrition and reduced immunity in children.However, on the other hand, excess nutrition is also harmful.

Although nutritional deficiency is the key reason for children's poor immunity, excessive nutrition can also lead to poor immunity.For example, some babies are fed too frequently, and some mothers feed their babies whenever they cry, without paying attention to whether it exceeds the child's needs.

Some parents also add too many supplementary foods to their children, making them grow too fast, and at the same time, they lack exercise, which can also lead to poor immunity.Therefore, to enhance a child's immunity, nutrition is not simply more is better.Here, I especially want to remind everyone that many parents are worried that their children have poor immunity and are prone to colds and fevers, so they give their children supplements, health products, or vitamins, and also ask the doctor to prescribe medications to improve immunity.I want to say that if your child does not have a congenital immune system problem, they don't need to supplement nutrients. If you supplement nutrients randomly or excessively, it will interfere with the immune system and cause more problems.If you want to enhance your child's immunity, the safest and most direct way is to ensure that your child gets enough nutrients every day, including water, grains, vegetables, fruits, beans, eggs, and dairy products. All types of food should be as balanced as possible.

Only in this way can children gradually develop strong immunity, and be protected by the immune system every day in their lives, and stay away from various diseases.Regarding this, I want to say that if your child does not have a congenital problem with the immune system, they do not need to supplement nutrients specifically, and if they supplement nutrients arbitrarily or excessively, it will interfere with the immune system and cause endless problems.

If you want to enhance your child's immunity, the safest, most direct, and most effective way is to require your child to consume enough nutrients every day, including water, grains, roots and tubers, vegetables, fruits, beans, eggs, dairy, and oils, and to try to consume all kinds of food in a balanced way.In this way, your child can gradually develop a strong immune system and be protected by the immune system every day of their life, staying away from small and large diseases.
