Managing zinc deficiency in an office setting

Zinc, an important nutrient in the human diet, is involved in a host of metabolic processes necessary to maintain good health. Zinc deficiency is widespread, even among otherwise well-nourished populations. The zinc taste test is a convenient method of assessing zinc deficiency in a clinical setting. In this article, the procedures followed in administering the zinc taste test are described. Results of performing the test on a sample of convenience (20 family practice residents and faculty members) indicated that only 20% had no zinc deficiency and 15% were severely deficient. The high prevalence of zinc deficiency and the importance of zinc in maintaining good health establish the need for regular zinc level screenings. Because the zinc taste test is so easy to perform, those screenings can be performed in a primary care office setting.
