introduction: zinc has been known as an essential trace element in human, animal and plant nutrition. during pregnancy, the daily requirement increases to 25% and its serum level decreases. the serum level of zinc in adults is arranged from 80 to 150 μg/dl. considering the importance of this trace element and its role during pregnancy, this study was conducted on pregnant women in the community...

Zinc is essential micronutrients for proteins production in plants; also zinc is main composition of ribosome and is essential for their development. Zinc is active element in biochemical processes and has a chemical and biological interaction with some other elements. Phosphorus is the most important element which interferes on zinc uptake by plants. Phosphorus is the important element that in...

BACKGROUND Zinc deficiency affects multiple vital functions in the life cycle, especially growth. Limited information is available on the magnitude of zinc deficiency in Latin America and the Caribbean. OBJECTIVE To examine the latest available information on both the prevalence of zinc deficiency and the risk of zinc deficiency in Latin America and the Caribbean. METHODS The prevalence of ...

Zinc deficiency is a global problem of considerable importance for agriculture and human health. Under zinc deficiency conditions, many essential zinc-dependent physiological functions are unable to operate normally, and the cellular homeostasis is adversely affected. This paper described the potential damages that low-zinc bioavailability in soil can have for plants, humans, and animals. In ad...

Zinc deficiency reduces intake and produces an unusual approximately 3.5-d cycle of intake in rats. The mechanism underlying the anorexia and cycling has not yet been defined; current hypotheses suggest that alterations in amino acid metabolism and neurotransmitter concentrations may be a part of this anorexia. Recent reports indicate that appetite-stimulating neuropeptide Y (NPY) may be elevat...

OBJECTIVE Zinc deficiency is a problem world-wide. Zinc and insulin are intimately related, and a reduced zinc intake may affect glucose metabolism. The present study investigates how subclinical zinc deficiency in rats affects glucose metabolism and zinc distribution in the pancreas. METHODS Glucose metabolism was evaluated by blood-glucose, serum insulin, homeostasis model assessment (HOMA)...

A 33% of elderly people in the world are at risk of zinc deficiency.1 Reports from different countries have shown prevalence of zinc deficiency among old people.2-4 Diet surveys indicate that zinc intake in the elderly are often inadequate. Several factors may contribute to poor zinc nutrition among the elderly. These include reduction in food intake due to reduced mobility or depression, and p...

Introduction There are several reports of zinc deficiency in pathogenesis of acute and chronic diarrhea. The literature review showed children with diarrhea and chronic gastroduodenitis performed zinc deficiency in majority of cases (1). The normal values of zinc in blood serum are 12.8-27.8 μmol/l (2). There is a threshold of 13μmol/l zinc concentration for zinc deficiency diagnosis. The zinc ...

Iron deficiency is prevalent in children and infants worldwide. Zinc deficiency may be prevalent, but data are lacking. Both iron and zinc deficiency negatively affect growth and psychomotor development. Combined iron and zinc supplementation might be beneficial, but the potential interactions need to be verified. In a randomized, placebo-controlled trial using 2 x 2 factorial design, 609 Thai ...

Zinc is an essential element whose significance to health is increasingly appreciated. In 1961 essentiality of zinc for humans was recognized. A systematic literature search was done to identify relevant studies investigating the role of zinc in human health. This review concerns the importance of zinc in health and the consequences of its deficiency. Zinc deficiency leads to complications of p...
