Zinc is an essential mineral of great importance to human health and general function, having a role in taste perception, growth regulation, immunocompetence, neural development and function, and reproduction‐associated processes. Zinc deficiency can lead to diarrhea, loss of motor function, pneumonia, anorexia, and dysgeusia. Despite its importance, a non‐invasive, reliable method of assessing zinc nutriture has yet to be established. The Bryce‐Smith zinc taste test (ZTT) was created based on the strong link between zinc nutriture and taste perception. We compared the results of ZTT scores against scores from a novel visual analog scale (VAS) over a population of 491 college‐age students. Individuals were also given a heath history questionnaire to account for known latent factors. A significant correlation was calculated when ZTT scores (1–4) were compared to VAS (0–100) scores (p‐value<0.01; R2=0.60). A significant correlation was found between averaged VAS scores and ZTT scores (p‐value< 0.01; R2>;0.99). Because the VAS correlates to the ZTT and assesses zinc with a greater range of data points, it appears to be a useful, and potentially more sensitive, adjuvant to the Bryce‐Smith ZTT.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
