Define about the Zinc Deficiency?

Evidence suggests that nearly one-third of preschool children in lower-income countries have stunted growth, and that a considerable proportion of this growth failure is likely attributable to zinc deficiency. Zinc is a cofactor for a large number of 200 metalloenzymes, which regulate several cellular functions of the body. Zinc is essential for cell division and growth, stabilization of bio-membranes, protection against free radical damage, immune function and its possible role in testosterone production. Zinc, in the recent past, has attained an important place as an important trace element. We will briefly study here the signs and symptoms and the consequences of zinc deficiency and the recommended daily requirements for zinc.
