Several trace elements required by children

Trace elements are necessary to maintain the physiological activities of some enzymes or hormones in the body. If certain trace elements are absent, the enzyme's vitality is affected.
iron
Iron is the most abundant trace element and is one of the constituents of hemoglobin, myoglobin, and many important enzymes. Normal adults have 3-5 grams of iron (40-55 mg/kg), which is slightly lower for women. When the baby is born, there is a certain amount of quality in the liver, and the consumption is gradually reduced to 4-5 months. Therefore, it is necessary to supplement the iron-containing substances in time, such as liver, egg yolk, lean meat, vegetables, and fruits. Children need about 15-18 mg of iron per day, and long-term iron deficiency in food can cause iron deficiency anemia.
Zinc
Zinc is found mainly in bones, skin and hair in the human body. The zinc content of hair is generally considered to reflect the long-term supply of zinc in the diet. Zinc is a constituent of many metalloenzymes or activators of enzymes. Many studies have shown that zinc is closely related to the biosynthesis of RNA, DNA and protein. Zinc can assist in the transport of glucose on the cell membrane. In addition, zinc is also involved in energy metabolism, hormone effects, and transport of vitamin A. Zinc has an important influence on the bactericidal tropism and phagocytic ability of phagocytic cells.
Zinc deficiency showed growth arrest, decreased taste, lack of appetite, anorexia, omnivorous, naive, and poor wound healing. Colostrum contains a lot of zinc, followed by a decrease in the concentration of lactation. General animal food is a reliable source of zinc, such as beef, pork, mutton, fish and other seafood products are also higher, because the grain contains phytate, can combine with zinc and reduce the utilization of zinc. Vegetables and fruits generally contain very little zinc. The average infant needs 5 mg of zinc daily, 10 mg for 1-10 years, 15 mg for adults, and 20-25 mg for pregnancy and lactation.
iodine
The main function of iodine is to participate in the formation of thyroxine. Healthy adults have about 8 mg of iodine in the thyroid gland, and local goiter patients can fall below 1 mg. Adults are generally considered to be able to ingest 100-150 mg of iodine per day, which can meet physiological needs, but children, pregnant women, nursing mothers, and strong laborers should be appropriately increased. Iodine deficiency can cause cretinism in children and goiter in adults. Iodized salt, seafood, and seaweeds are all major sources of iodine.
