Description

<p> Taste is an important sense that is associated with appetite and food intake. Although many studies have been reported on taste detection tests in patients with taste disorders, few studies have been conducted in healthy subjects.</p><p> The Iwaki Health Promotion Project is a large-scale epidemiological survey of local residents. In the present study, participants in Project 2019 were tested for sweet, salty, sour, and bitter taste thresholds, and 1027 participants for whom data were available were included in the analysis.</p><p> A comparison of the taste thresholds among the age groups showed that the sour and salty tastes thresholds increased significantly with age, and the thresholds for all tastes was significantly lower in women than in men. In addition, decreased serum zinc levels were not necessarily associated with decreased taste, but decreased serum zinc levels and decreased taste were more frequently observed in the elderly. There were quite a few patients who were not aware of any taste disorder, even though they had a decreased sense of taste on examination. This indicates that there are potential patients with taste disorders.</p>
