Taste is influenced by factors from our environment, psychology, and from our own physiological state. The objective of the study was to determine whether sleep influences our sense of taste or our cravings for food.
57 healthy panelists, predominantly of college age, submitted to sleep tracking, and subsequently underwent a series of sensory tests, using basic prototypic tastants, as well as real foods. Panelists were also evaluated to quantify food cravings, using both the Leeds Food Preference Questionnaire, and the Control of Eating Questionnaire.
Umami (p = 0.025, F = 5.301) and sour (p = 0.037, F = 4.591) taste were intensified in those rating sleepiness higher, while this group also reported higher implicit wanting for high fat sweet foods (p = 0.011, Wald chi-sq = 14.937). Craving for sweet or savory also associated with a number of measures of taste response to real foods.
Results imply that a lack of sleep may induce cravings for unhealthy foods, and that foods high in umami or sour taste may be experienced differently due to alterations in taste function. Results imply that feeding behavior may be influenced by a lack of sleep, acting at least partially through our sense of taste.
味觉受到环境、心理和自身生理状态等因素的影响。本研究旨在确定睡眠是否会影响我们的味觉或对食物的渴望。
57 名健康的小组参与者，主要是大学生，接受了睡眠跟踪，随后进行了一系列感官测试，使用基本的原型味觉剂和真实食物。还使用利兹食物偏好问卷和饮食控制问卷评估了参与者对食物的渴望程度。
在那些睡眠评分较高的人中，鲜味（p=0.025，F=5.301）和酸味（p=0.037，F=4.591）的味觉增强，而这群人也报告了更高的隐性高脂肪甜食渴望（p=0.011，Wald chi-sq=14.937）。对甜或咸的渴望也与对真实食物味觉反应的多项测量值相关。
结果表明，睡眠不足可能会引起对不健康食物的渴望，而高鲜味或酸味的食物可能由于味觉功能的改变而有不同的体验。结果表明，喂养行为可能会受到睡眠不足的影响，至少部分通过我们的味觉。
