Patient's question:
How can zinc be supplemented from food? He doesn't sleep for long, and he cries often. He gets terrified and starts crying if the sound is loud. He is now seven and a half months old. I wonder if he might have bronchitis, as he coughs frequently.Doctor's answer:
Hello, zinc is a trace element that indirectly regulates metabolism in children, particularly in terms of protein synthesis, the production and secretion of growth factors, etc.Zinc deficiency in infants and young children can lead to a decline in the activity of zinc-containing enzymes, resulting in delayed growth and development, poor appetite, and even refusal to eat. If a child exhibits these symptoms and zinc deficiency is suspected, it is essential to consult a doctor for tests such as hair zinc and blood zinc. After a definitive diagnosis of zinc deficiency, zinc supplements should be taken under medical guidance. However, some parents mistakenly give zinc supplements to infants as a nutritional supplement in large quantities for a long time, unaware that excessive zinc intake can also cause harm, such as weakening the immune system and affecting iron utilization, leading to anemia.
The best way to supplement zinc in daily life is through food. It has been determined that animal-based foods are rich in zinc (3–5 milligrams per 100 grams) and have a high absorption rate of about 50%. In contrast, plant-based foods contain less zinc (1 milligram per 100 grams) and have a much lower absorption rate of only 10%–20%. Therefore, to prevent zinc deficiency, children should be encouraged to eat more animal-based foods such as lean meat, pork liver, and egg yolks, while also developing good habits like not being picky eaters. If zinc deficiency occurs, there is no need to panic. Taking zinc sulfate or gluconate zinc under medical guidance can correct the deficiency, significantly improve appetite, and gradually accelerate growth and development. The entire course of treatment should involve taking medication for 2–3 months.
At the same time, experts warn that indiscriminate zinc supplementation can be harmful to children. Excessive zinc intake can damage the liver, and in severe cases, it may lead to jaundice and hepatitis.
