How to supplement zinc for children
Zinc deficiency in infants will reduce the activity of zinc-containing enzymes, leading to growth retardation, loss of appetite and even refusal to eat. When children have the above symptoms and are suspected of zinc deficiency, they should ask a doctor to check their hair and blood zinc. After the diagnosis of zinc deficiency, you should take zinc supplement products under the guidance of a doctor. At present, due to a lot of publicity about the dangers of zinc deficiency, some parents mistakenly take zinc products as nutrients for infants for a long time. As we all know, excessive zinc supplementation can also bring harm, such as weakened immune function, affecting the utilization of iron and causing anemia.
Therefore, the best way to supplement zinc in daily life is to supplement zinc through food. Its specific methods: First, advocate breastfeeding. Secondly, eat more foods containing zinc. Foods rich in zinc include oysters, herring, shrimp skin, seaweed, fish meal, sesame, peanuts, pork liver, beans and so on. Third, overcome the habit of partial eclipse. Diet should be diversified, and refined foods, such as refined white rice and refined noodles, should be eaten less.

Supplement zinc, don't follow the trend.
Zinc is a trace element. For children, zinc indirectly regulates metabolism, especially the synthesis of protein and the production and secretion of growth factors. So when zinc is deficient, these links needed for growth are blocked. Mucosa and skin are tissues with rapid metabolism and renewal. Dermatitis and skin damage can occur when zinc is deficient, and it is not easy to heal. The effects on mucosa are dull taste, anorexia, abnormal digestion and absorption, which will aggravate the growth disorder.
Compared with adults, children are more prone to zinc deficiency, and rapid growth and development is one reason. Children often have the habit of picky eaters and partial eclipse, but for a child with a balanced diet, especially a reasonable intake in protein, zinc is generally not lacking.
Because zinc exists in foods containing protein, such as meat, milk, eggs and beans. There are many reasons for growth retardation, and the diagnosis methods are complicated. Only after detailed examination and diagnosis by doctors can targeted treatment be given.
If children are not short of zinc, parents blindly give their children all kinds of products containing zinc, which is harmful instead of encouraging them. Too much zinc will cause damage to the liver, and jaundice hepatitis will appear in severe cases, so zinc supplementation should be cautious.
To prevent zinc deficiency in children, it is best for infants to breastfeed, because human milk is high in zinc and easy to absorb, and animal food is high in zinc and easy to absorb; Therefore, it is very necessary to add animal liver, egg yolk, minced meat, fish paste and other auxiliary foods rich in trace elements to infants. For children, zinc deficiency can be prevented by insisting on dietary diversification, reasonably arranging recipes, cultivating good eating habits, and not being partial or picky about food.

My child is eight months old and weighs 8 kg. The results of trace element examination show that he is short of zinc, so he needs to take zinc gluconate oral liquid (Sanjing brand). Excuse me, doctor, how to master the dose of zinc supplement and how long will it take? What are the precautions? thank you

Zinc is a trace element. For children, zinc indirectly regulates metabolism, especially the synthesis of protein and the production and secretion of growth factors.
Zinc deficiency in infants will reduce the activity of zinc-containing enzymes, leading to growth retardation, loss of appetite and even refusal to eat. When children have the above symptoms and are suspected of zinc deficiency, they should ask a doctor to check their hair and blood zinc. After the diagnosis of zinc deficiency, you should take zinc supplement products under the guidance of a doctor. However, some parents have long mistakenly regarded zinc products as nutritional products for babies, but they do not know that excessive zinc supplementation will also bring harm, such as weakened immune function, affecting the utilization of iron and causing anemia.
The best way to supplement zinc in daily life is through food. According to the determination, animal food is rich in zinc (3 ~ 5 mg/ 100 g), and the absorption rate is as high as 50%. Plant food contains less zinc (1 mg/ 100 g), and its absorption rate is only 10% ~ 20%. It can be seen that to prevent zinc deficiency, children should be encouraged to eat more animal foods such as lean meat, pig liver and egg yolk, and develop a good habit of not being partial to food and not picky about food. Once zinc is lacking, there is no need to be nervous. As long as you eat some zinc sulfate or zinc gluconate under the guidance of a doctor, you can correct zinc deficiency, obviously increase your appetite and gradually accelerate your growth and development. During the whole treatment, you should take medicine for 2 ~ 3 months.
At the same time, experts say that blind zinc supplementation is harmful to children, too much zinc will cause damage to the liver, and in severe cases, jaundice hepatitis will occur.
(1) weakened immune function: under the action of magnesium ions, zinc can inhibit the activity of phagocytes and reduce their chemotaxis and bactericidal effects. Under normal circumstances, this effect will be inhibited by serum protein and calcium ions. Therefore, people with low calcium and children with rickets will consume too much zinc, resulting in impaired immune function and weakened disease resistance;
(2) Affect the utilization of iron: reduce the iron content in blood, kidney and liver, leading to iron deficiency anemia;
(3) The disorder of cholesterol metabolism leads to the increase of zinc-copper ratio, which leads to hypercholesterolemia and easy to cause atherosclerosis.
Scientific research shows that zinc is a component of more than 200 enzymes in human body, which directly participates in the synthesis of nucleic acid and protein, cell differentiation and proliferation, and many important metabolism. There are still some enzymes in human body that need zinc activation to play their active role. Zinc is an essential substance in human growth and development, reproductive genetics, immunity, endocrine, body fluids and other important physiological processes. When the total amount of zinc in human body decreases, it will cause immune tissue damage and immune function defect, so zinc is known as "flower of life". So which human physiological activities are zinc mainly related to?
Relationship between zinc and human physiological activities;
1. Promote children's intellectual development. Children with zinc deficiency have poor intelligence development, while children with relatively high zinc content in their bodies have better intelligence and excellent academic performance, so zinc can promote intelligence development.
2. Accelerate the growth and development of teenagers. Zinc is involved in the synthesis of hormones closely related to physical development, so it has special nutritional value for developing teenagers.
3. Maintain and promote vision development. The zinc content in human eyes is high, and the zinc content in retina and choroid is the highest. Zinc participates in the synthesis of a reductase in liver and body, which is the key enzyme leading to the synthesis and allosteric change of visual substances (retinaldehyde), so zinc deficiency will affect vision and dark adaptation.
4. Affect taste and appetite. Taste hormone is a saliva protein containing two kinds of zinc ions in saliva, and it is an important nutritional factor for the structure, function and metabolism of oral mucosal epithelial cells. When zinc is deficient, the epithelial cells of oral mucosa proliferate and keratinize incompletely, the half-incubation period is shortened, and they are easy to fall off, covering up and blocking the pores of the taste buds of tongue papilla, making it difficult for food to contact the taste buds, affecting taste, and thus affecting appetite.
5. Trace elements related to male fertility. Trace elements related to fertility mainly include zinc, copper, selenium, manganese and magnesium. Among these trace elements, zinc deficiency is the most common. When zinc is insufficient, the pituitary gland is affected, which leads to the decrease of gonadal hormone secretion, which can make gonadal dysplasia or hinder the endocrine function of gonads.
6. Zinc deficiency can lead to Alzheimer's disease. If zinc content is insufficient, memory loss, limb movement disorder, abnormal thinking function and even early onset Alzheimer's disease will occur in old age.
7. Important trace elements for maintaining other functions of human body. Zinc can increase the regeneration ability of wound tissue, thus promoting the regeneration of wound tissue, thus promoting wound healing and curing dermatitis. Zinc is closely related to many skin and mucosal diseases. Zinc can also improve the proliferation ability of immunocompetent cells, stimulate antibody reaction and improve immune function.
