Sensitivity to savory taste has been linked to high consumption of savory foods and increased risks of obesity and hypertension. However, there are limited studies that investigate whether obesity indices are correlated with the differences in umami taste perception, particularly in children. This study aimed to investigate the umami detection threshold among children of different ethnicities and the threshold's correlation with obesity indices and blood pressure. A total of 140 subjects were recruited and consisted of a nearly equal distribution of children from three main ethnicities (37.2% Malays, 31.4% Chinese, 31.4% Indians). Umami detection threshold was measured using the two-alternative, forced-choice staircase procedure. Body weight, height, waist circumference and blood pressure of children were measured. Body composition was assessed using bioelectrical impedance analysis (BIA). Mean umami detection threshold was 1.22 ± 1.04 mM and there were no observable differences attributable to the subjects' ethnicities. Body fat percentage was negatively correlated (r = -0.171, p < 0.05), while lean body mass percentage was positively correlated (r = 0.171, p < 0.05) with umami detection threshold. These findings revealed that umami taste perception correlated with children's body composition, but not other anthropometric indicators and blood pressure. Future studies should explore the correlation between umami taste perception and children's total dietary intake.
对鲜味的敏感度与高盐食物的高摄入量以及肥胖和高血压风险的增加有关。然而，研究鲜味味觉感知差异与肥胖指数之间关系的研究有限，尤其是在儿童中。本研究旨在调查不同种族儿童的鲜味检测阈值，以及该阈值与肥胖指数和血压的相关性。共招募了140名受试者，其中来自三个主要种族的儿童分布几乎相等（马来人占37.2%，华人占31.4%，印度人占31.4%）。使用二项迫选阶梯法测量鲜味检测阈值。测量了儿童的体重、身高、腰围和血压。使用生物电阻抗分析（BIA）评估身体成分。鲜味检测阈值的平均值为1.22±1.04 mM，未观察到因受试者种族而产生的差异。体脂百分比与鲜味检测阈值呈负相关（r = -0.171，p < 0.05），而瘦体重百分比与鲜味检测阈值呈正相关（r = 0.171，p < 0.05）。这些发现表明，鲜味味觉感知与儿童的身体成分相关，但与其他人体测量指标和血压无关。未来的研究应探索鲜味味觉感知与儿童总膳食摄入量之间的相关性。
