Compared with normal-weight individuals, obese young adults exhibited a significantly higher taste threshold for salty taste. Smoking also affected taste functions in this population.
The aim of this study was to investigate the differences in taste detection thresholds between normal-weight and obese young adults.
Taste threshold was measured using electrogustometry (EGM) and chemically with sucrose, NaCl, citric acid, and quinine hydrochloride in 41 volunteers in their twenties, 23 with body mass index (BMI) <23 kg/m(2) (normal-weight group) and 18 with BMI >25 kg/m(2) (obese group).
BMI was significantly higher in the obese than in the normal-weight group (p < 0.05). The obese group exhibited significantly higher EGM thresholds than the normal-weight group on the right (p < 0.05) and left (p < 0.05) posterior tongue. In chemical taste tests, the obese group had higher thresholds for sweet, salty, sour, and bitter tastes than the normal-weight group, although the difference in threshold was significant only for salty taste (p < 0.05). Smoking had an impact on taste threshold, with smokers having higher thresholds than non-smokers, with significantly higher EGM thresholds on the right anterior and posterior and the left anterior tongue (p < 0.05 each).
与体重正常的个体相比，肥胖的年轻成年人对咸味的味觉阈值显著更高。吸烟也会影响该人群的味觉功能。
本研究旨在调查体重正常和肥胖的年轻成年人之间味觉检测阈值的差异。
使用电味觉测量法（EGM）以及通过蔗糖、氯化钠、柠檬酸和盐酸奎宁进行化学测量，对41名二十多岁的志愿者进行味觉阈值测量，其中23人体重指数（BMI）<23 kg/m²（正常体重组），18人体重指数>25 kg/m²（肥胖组）。
肥胖组的BMI显著高于正常体重组（p < 0.05）。肥胖组右侧（p < 0.05）和左侧（p < 0.05）舌后部的EGM阈值显著高于正常体重组。在化学味觉测试中，肥胖组对甜味、咸味、酸味和苦味的阈值均高于正常体重组，不过仅咸味阈值的差异具有统计学意义（p < 0.05）。吸烟对味觉阈值有影响，吸烟者的阈值高于非吸烟者，右侧舌前部和后部以及左侧舌前部的EGM阈值显著更高（均为p < 0.05）。
