Role of Zinc in Malnutrition

Malnutrition is a globally prevalent disease, more so in the developing countries. It includes both macronutrient and micronutrient or trace element deficiency. Of late, zinc has been recognized as an essential trace element, required for maintaining normal body homeostasis. Zinc deficiency is associated with growth retardation (height and weight), delayed sexual and bone maturation, impaired immune function, recurrent infections, dermatitis, diarrhoea, alopecia, anorexia and mental disturbances. Serum zinc levels have been found to be low in protein energy malnutrition globally. Zinc supplementation during the rehabilitation phase of malnutrition has been associated with rapid weight gain.
