A comprehensive review is presented concerning the role of zinc (Zn) nutrition in taste acuity, immunity and wound recovery in the elderly. Specific attention is given to Zn in foods, Zn bioavailability, evidence of Zn deficiency, and the need for Zn in immune function. It was concluded that the mean daily Zn intake in groups of US elderly ranges from 7-13 mg. Dietary Zn intake appears to be related to energy intake. An apparently adequate Zn intake can be achieved for $1.50-2.00/day with careful food selection; hence, people spending below $1.50/day for food have limited ability to satisfy dietary Zn requirements. Further Zn bioavailability should be considered in the food selection process. Evidence suggests that some elderly individuals have a deficient Zn nutriture, but available data are insufficient to ascertain the frequency of this deficiency. Most instances of hypogensia in the elderly, however, are unrelated to Zn nutriture. Deficient Zn nutriture seems to contribute to poor healing in the elderly, but, again, the data are too few to ascertain frequency. Self-treatment with Zn greater than the RDA may be unwise. (wz)
