Dietary intakes and zinc status of an elderly rural population

Extract: The zinc status and energy, protein, and zinc intakes of a group of 50 individuals, 65 years of age or older, residing in rural Pennsylvania have been described. Generally, this group was in good zinc status, although zinc intakes were considerably less than the RDA for most individuals. Energy intakes were generally adequate and protein intakes more than sufficient. It would appear possible to maintain adequate zinc status (as assessed by plasma and hair zinc determinations) with zinc intakes of less than the RDA; this may be facilitated by adequate energy and more than sufficient protein intakes.
