Summary
This narrative review, published in the Journal of Research in Medical Sciences, synthesises the available literature on zinc as an essential micronutrient, covering its biochemical functions, health consequences of deficiency, and dietary considerations. The authors likely examine the global burden of zinc inadequacy, particularly in populations reliant on plant-based diets with high phytate content that inhibits zinc bioavailability. The paper is expected to provide a reference framework for clinicians and nutritionists on zinc assessment, recommended intakes, and the implications of deficiency for immune function, growth, and reproduction.
UK applicability
Whilst the review is international in scope, its findings are broadly applicable to UK public health contexts, particularly regarding dietary zinc adequacy in vulnerable groups such as vegetarians, the elderly, and those with low meat consumption, which is relevant to ongoing UK nutritional surveillance and dietary guidance.
Key measures
Serum zinc concentrations; dietary zinc intake (mg/day); prevalence of zinc deficiency; absorption and bioavailability indicators
Outcomes reported
The paper reviews the physiological roles of zinc in the human body, examines the consequences of zinc deficiency across populations, and discusses dietary sources, absorption factors, and supplementation strategies.
