Variation in ability to detect, recognize, and perceive sweetness may influence food consumption, and eventually chronic nutrition-related conditions such as overweight and obesity. The aim of this study was to investigate the associations between sweet taste function, anthropometry, and dietary intake in adults. Participants' (n = 60; mean age in years = 26, SD = ±7.8) sweet taste function for a range of sweeteners (glucose, fructose, sucrose, sucralose, erythritol, and Rebaudioside A) was assessed by measuring detection and recognition thresholds and sweetness intensity. Height, weight, and waist circumference were also measured, and participants also completed a Food Frequency Questionnaire. There was large inter-individual variation in detection, recognition and sweetness intensity measures. Pearson's correlation coefficient revealed no robust correlations between measures of sweet taste function, anthropometry, and dietary intake, with the exception of suprathreshold intensity, which was moderately correlated with total energy intake (r = 0.23-0.40). One-way analysis of variance revealed no significant differences between the most and least sensitive participants in terms of BMI, waist circumference, and dietary intake for all measures of sweet taste function and sweeteners (all p > 0.01). When stratified into BMI categories, there were no significant differences in any measure of sweet taste function between the normal weight and overweight/obese participants (all p > 0.01). Results show that that sweet taste function is not associated with anthropometry and sweetness intensity measures are the most appropriate measure when assessing links between sweet taste and food consumption.
检测、识别和感知甜味能力的差异可能会影响食物摄入量,并最终影响与营养相关的慢性疾病,如超重和肥胖。本研究旨在调查成年人甜味功能、人体测量学指标和饮食摄入量之间的关联。通过测量检测阈值、识别阈值和甜味强度,评估了参与者(n = 60;平均年龄26岁,标准差 = ±7.8)对一系列甜味剂(葡萄糖、果糖、蔗糖、三氯蔗糖、赤藓糖醇和莱鲍迪苷A)的甜味功能。还测量了身高、体重和腰围,参与者还完成了一份食物频率问卷。在检测、识别和甜味强度测量方面,个体间存在很大差异。皮尔逊相关系数显示,除了阈上强度与总能量摄入量呈中度相关(r = 0.23 - 0.40)外,甜味功能测量、人体测量学指标和饮食摄入量之间没有显著相关性。单因素方差分析显示,在所有甜味功能测量指标和甜味剂方面,最敏感和最不敏感的参与者在BMI、腰围和饮食摄入量方面没有显著差异(所有p > 0.01)。按BMI类别分层时,正常体重参与者和超重/肥胖参与者在任何甜味功能测量指标上均无显著差异(所有p > 0.01)。结果表明,甜味功能与人体测量学指标无关,在评估甜味与食物消费之间的联系时,甜味强度测量是最合适的指标。
