Zinc deficiency in children can lead to lack of appetite, taste disorder (paranoia, anorexia or heterophagia), stunted growth (dwarfism, thinness, baldness), gastrointestinal disorders (diarrhea), dermatitis (rash, eczema, poor wound healing, recurrent mouth ulcers), recurrent infections and colds, delayed neuro-intellectual development, incomplete sexual development, impaired brain development, etc. Nutritional guidance for zinc deficiency 1. Diversify food, avoid picky eating, eat more animal food, especially oysters, sea oysters, oysters, shellfish and other seafood, and secondly, beef, lamb, pork and animal offal are also excellent sources of zinc. The intake of zinc-rich foods by women during pregnancy and lactation can help increase the zinc content in breast milk. 2. If the conditions are limited, interventions for children in zinc-deficient areas, i.e., zinc supplementation or zinc-fortified foods, can be given. 3.Oral administration of easily absorbed zinc sulfate, zinc acetate and zinc gluconate is now considered to bring the blood zinc to the required level even in smaller doses, 15-20 mg orally, preferably after meals. 4. Children with enteropathic acrodermatitis (AE) due to severe zinc deficiency can be treated with zinc sulfate, which is more effective. 5. Children who require parenteral nutrition due to their condition need to be treated with zinc in a vein.
