It plays an important role in the metabolism of almost all cells. Therefore, zinc is an indispensable substance for children's growth and development.
Method of zinc supplement
1. Food supplement: the infant relies on breast milk for zinc supplement, at least for 3 months. The absorption rate of zinc in breast milk is high, up to 62%.
After weaning, add zinc rich foods, such as beef, mutton, pork lean meat, peanuts, soybeans, carrots, oysters, etc. According to the determination, the zinc content of animal food is higher than that of plant food, and the amino acids produced after the decomposition of animal protein can promote the absorption of zinc, with the absorption rate generally around 50%; while the zinc contained in plant food can combine with plant acid and cellulose to form insoluble compounds, thus hindering the absorption of human body, with the absorption rate around 20%.
Note: over processing of food will damage zinc. Therefore, when cooking food, you should control the temperature to reduce the loss of zinc.
When the content of iron, calcium, phosphorus and copper in food is too high, the absorption and utilization rate of zinc will be reduced. We should ensure the diversification of food in our daily diet and strive to achieve a balanced diet.
