Zinc is one of the essential micronutrients and has an important role in the maintenance of human health. Older adults are particularly vulnerable to zinc deficiency due to poor intake of zinc-rich foods. Zinc deficiency may result from poor intake due to alterations in both olfactory and gustatory sensations in addition to difficulty in mastication from poor dentition, or due to inadequate absorption resulting from excess consumption of phytate-containing products that inhibit the absorption of zinc. This review focuses on the clinical consequences associated with zinc deficiency among older adults.
Key words: zinc, deficiency, older adults, clinical manifestations.
