How to make sure your older patients are getting enough zinc

Older patients with inadequate dietary habits tend to be at risk for mild to moderate zinc deficiency. Symptoms that can be of particular concern include slow wound healing, increased risk of infection, and a loss of acuity in taste and smell. The diagnosis of zinc deficiency is based on a review of the patient's eating habits; laboratory testing is not generally useful in the clinical setting. Most older adults can achieve an adequate zinc intake by eating a variety of foods each day, including meat, fish, and poultry. Supplementation is appropriate in cases of known or suspected frank zinc deficiency.
