So what effect does zinc have on children's growth? Zinc participates in the synthesis of more than 200 kinds of enzymes, which can affect children's physical growth, intellectual development, immune function, wound healing and other physiological functions by affecting the activity of enzymes. At present, we think that zinc is one of the most important trace elements. Children are in the stage of growth and development, and their metabolism is vigorous. Reasonable nutrition can not only ensure their normal growth and development, but also lay a good foundation for their health as adults.
What harm does zinc deficiency bring to children? The combination of zinc and saliva protein can improve children's appetite. Zinc deficiency will affect their taste and appetite and even lead to pica. For example, in daily life, some children are sometimes seen eating cinders, clods, paper and hair. Another harm of zinc deficiency is that it affects growth and development. Zinc can play a role by forming various enzymes containing zinc, and can also participate in the synthesis and secretion of growth hormone. Zinc deficiency leads to growth and development stagnation, and the typical disease is zinc deficiency dwarf syndrome. Therefore, zinc has very important nutritional value for infants, children and adolescents with vigorous growth and development.
Zinc is very important for children's growth. Zinc deficiency will have a bad effect on children's system. What causes zinc deficiency in children?
1. Insufficient intake. Children's partial eclipse and picky eaters will cause insufficient zinc intake. For example, eat less animal food. Animal food contains much more zinc than plant food, and it is easier to be absorbed and utilized by human body. There are also long-term consumption of refined rice flour and other grains, which will cause insufficient zinc intake. Because grains will cause the loss of zinc in the finishing process.
2. Intestinal absorption dysfunction. Children with chronic digestive diseases, chronic diarrhea and gastrointestinal malabsorption.
The demand for zinc has increased. Growth and development period, disease recovery period, etc. The demand for zinc has increased.
4. Too much zinc is lost. Some diseases such as long-term hyperhidrosis and chronic diarrhea can lead to excessive zinc loss in the body.
5. Genetic defects. Due to the functional defect of zinc absorption in the small intestine, the zinc content in the body is reduced.
What food should I eat to supplement zinc? The best food source of zinc supplement is shellfish, such as oysters and shellfish, and the utilization rate of zinc in these substances is also high; Followed by animal liver, mushrooms, nuts and beans; Meat (mostly red meat) and eggs also contain a certain amount of zinc. Zinc in animal food is more easily absorbed by human body, while phytic acid and cellulose in plant food are not conducive to zinc absorption.
