Parents have "zinc" eyes, children are not short of zinc.

Guide: Children pick on food, leading to zinc deficiency, serious consequences! Zinc is an essential micronutrient in the human body, involved in a variety of ways of cell metabolism in the human body, play a variety of biological roles, participate in the maintenance of children's growth and development, intellectual development and reproductive organ development, maintain normal appetite and taste, as well as immunity, trauma healing and other fields play a role.
of zinc deficiency in children in children? Mild zinc deficiency: mostly due to short-term zinc intake, symptoms and signs are more typical.
zinc deficiency: often seen in long-term zinc intake or accompanied by diarrhoeal diseases, diarrhea, growth retardation, anorexia, delayed sexual maturity, behavior changes and so on.
but mild, moderate zinc deficiency are not specific to zinc deficiency, so it is difficult to judge zinc deficiency.
Severe zinc deficiency: rare, generally occurs in children suffering from enteropathic limb dermatitis or long-term use of penicillin to treat hepatic bean-like nuclear degeneration (WD), with mouth, limb side dermatitis, diarrhea, hair loss triple signs as characteristics.
The clinical manifestations of zinc deficiency in children and adolescents of different ages are also different in newborns, infants, young children and preschool children: zinc deficiency is often impaired cognitive ability, behavioral and mood changes and other symptoms, severe zinc deficiency can be seen in limb or oral deral damage.
school-age children: more common hair loss, growth retardation, blepharitis and repeated infections.
adolescents: zinc deficiency can lead to delayed sexual maturation.
of zinc deficiency 1, dietary zinc intake is insufficient: 6 months after birth, infants and young children, exclusive breastfeeding can not meet their nutritional needs for zinc, the need to supplement zinc-containing complementary foods.
In plant foods, fruits, vegetables, root foods have low zinc content, grains, nuts and legumes because they contain phytic acid, which binds to zinc in the intestines to form insoluble compounds, which make zinc indigestible or absorbable.
if the diet is mainly plant-based, lack of meat and other zinc-rich animal foods, dietary zinc intake is insufficient and phytic acid intake is too much, easy to lead to zinc deficiency in children.
2, poor zinc absorption or excessive zinc excretion: children with digestive tract absorption disorders, such as children with inflammatory bowel disease, diarrhoeal disease, kidney disease, reduced absorption of zinc in the intestines, increased excretion, will cause zinc deficiency.
some babies take calcium, antaics and anti-gastric acid secretion drugs, but also reduce zinc absorption.
The amount of zinc needed by children of different ages is recommended by the Chinese National Health And Safety Commission in 2017 according to the dietary nutrient reference intake of Chinese residents.
to prevent zinc deficiency, first of all, to cultivate a good diet and balanced diet, do not let the baby develop a bad habit of eating.
0 to 6 months of age, infants who are under-breastfed or unable to breastfeed may choose zinc-reinforced formula.
more than 6 months of age should prefer zinc-fortified baby supplements or zinc-rich foods.
high levels of zinc are shellfish, such as oysters.
to get your child to take zinc supplements, you can get the most zinc intake by eating shellfish.
the daily zinc content of many foods is also very high, such as red meat (beef, lean pork, etc.), egg yolks, liver, fish, poultry, etc. , it is recommended that the source of zinc supplementation should be rich.
How to choose zinc supplements for high-risk groups prone to zinc deficiency, such as patients with chronic diarrhea and poor absorption syndrome, patients with long-term use of extraintestinal nutrition, etc., need to be regularly plasma / serum zinc testing, growth and development assessment, dietary assessment and other comprehensive judgment, whether appropriate oral zinc supplements are needed.
zinc supplement treatment should be oral administration, it is appropriate to choose easy to dissolve in water, easy to absorb, better taste, lower cost zinc supplement drugs.
WHO/UNICEF recommends routine zinc supplementation for diarrhea in children in the Guidelines for Acute Diarrhoeal Diseases.
suggested that the choice of water-soluble zinc salts is convenient for oral use, including zinc sulfate, zinc acetate and zinc glucoseate, zinc absorption utilization rate is higher, gastrointestinal reaction is small.
10mg of zinc per day for children under 6 months of age, and 20mg per day for children older than 6 months, for 10 to 14 days.
20mg is equivalent to zinc sulfate 100mg and zinc glucosate 140mg.
Oral zinc preparation precautions: 1, 30 minutes after meals to reduce gastrointestinal irritation; Excessive zinc supplementation also has some safety risks.
healthy children who eat a balanced diet do not lack zinc and do not need regular zinc supplements.
parents need to be wary of excessive zinc intake caused by zinc supplementation drugs.
the whow's maximum dose of oral zinc for children is currently set at 23 mg/d of the element zinc.
adverse reactions to zinc are rare in pediatric clinics and can cause symptoms such as nausea, vomiting, reduced appetite, diarrhea and headache, but high doses of zinc can be acutely toxic and can adversely affect the state of the immune system, iron, copper and cholesterol.
