Precautions for zinc supplementation:
1, supplement foods rich in zinc after weaning, such as beef and mutton, lean pork, 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 by protein decomposition of animals can promote the absorption of zinc, and the absorption rate is generally around 50%; Zinc contained in plant foods can combine with plant acids and cellulose to form water-insoluble compounds, which hinder human absorption, and the absorption rate is about 20%.
2. Precautions: Excessive food processing will damage zinc. Therefore, when cooking food, the heat should be controlled to reduce the loss of zinc. When the contents of iron, calcium, phosphorus and copper in food are too high, the absorption and utilization rate of zinc will decrease. We should ensure the diversification of food in our daily diet and strive to achieve a balanced diet.
