Zinc is one of the essential trace elements in human body. Its content is very small in human body, but they are very necessary to maintain human metabolism. Once lacking these essential trace elements, human body will have diseases and even endanger life. The content of zinc in human body is second only to iron. It is one of the 15 trace elements needed by human body.
Zinc is involved in the synthesis of more than 200 enzymes. It 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 regard zinc as one of the most important trace elements. Children are in the stage of growth and development, with vigorous metabolism. Reasonable nutrition can not only ensure the normal growth and development of children, but also lay a good foundation for their health in adulthood.
Zinc combines with salivary protein to form a taste element, which can enhance children's appetite. Zinc deficiency will affect taste and appetite, and even lead to pica. For example, in daily life, some children are sometimes seen eating cinders, clods, paper, hair, etc. Another harm of zinc deficiency is to affect growth and development. Zinc can play a role through the composition of various zinc containing enzymes, and can also participate in the synthesis and secretion of growth hormone. Zinc deficiency leads to stagnation of growth and development. 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 in children's growth. Zinc deficiency will have an adverse impact on children's systems.
1. Insufficient intake. Children's partial eating and picky eating will lead to insufficient zinc intake. For example, animals eat less food. The zinc content of animal food is much higher than that of plant food, and it is easier to be absorbed and utilized by human body. In addition, long-term consumption of refined rice noodles and other grains will lead to insufficient zinc intake. Because the grain will cause the loss of zinc in the finishing process.
2. Intestinal absorption dysfunction. Children suffering from chronic gastrointestinal diseases, long-term diarrhea and gastrointestinal malabsorption.
3. Increased demand for zinc. During the growth and development period and disease recovery period, the demand for zinc increases.
4. Too much zinc is lost. Some diseases, such as long-term sweating 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 content of zinc in the body is reduced.
The best food source of zinc supplement is shellfish, such as oysters and scallops. 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.
