Children can take zinc supplements by consuming zinc-rich foods or taking zinc-containing supplements, but there is no such thing as “which one is better”, and patients are advised to follow the doctor’s instructions. In daily life, children can eat zinc-rich foods, such as oysters, lean meat, animal liver, nuts, mushrooms, etc., which are relatively rich in zinc. Zinc-deficient children can adjust their diets to include more zinc-rich foods. If necessary, children with zinc deficiency can also take zinc-containing drugs, such as zinc gluconate, licorice and zinc granules. It is important to note that these two drugs should be used in accordance with medical advice, not blindly self-medication or long-term use, and can not be taken with milk, in order to avoid discomfort. For children with zinc deficiency, parents should pay attention and bring their children to the doctor in time, and the doctor should formulate a corresponding treatment plan to supplement zinc.
