Abstract

Women commonly report increased cravings for foods high in sugar, fat, and/or salt premenstrually relative to other times during the menstrual cycle. To determine if elevated cravings for foods high in salt and/or fat were related to alterations in food preferences across the menstrual cycle, preference and sensory ratings for air-popped popcorn with varying levels of salt (0.0, 1.5, and 4.0 g) and butter (3.3, 10, and 30 g) added to 30 g of popcorn were assessed in 34 normal-weight, college-aged women for 4 consecutive weeks. Additionally, using the Profile of Mood Scale (POMS), mood states were determined across the menstrual cycle. Dietary restraint, disinhibition, and hunger were assessed using the Three Factor Eating Questionnaire (TFEQ). Neither preference ratings nor ratings of the saltiness or fatness of the popcorn samples varied as a function of the menstrual cycle. Moreover, no differences in mood states were observed across the menstrual cycle. However, preference ratings for the popcorn samples were significantly greater for restrained than unrestrained eaters. Restrained eaters also rated the samples as significantly more salty, and had significantly higher scores on the tension-anxiety and depression-dejection subscale of the POMS than unrestrained eaters. Additionally, preference ratings of women who reported exercising more than 3 h a week were significantly greater than those of women who reported exercising less than 3 h a week. It is hypothesized that the variations in preference ratings observed as a function of dietary restraint and exercise are the result of differences in cognitive beliefs about food, rather than differences in physiological factors.

摘要

女性通常报告称,与月经周期中的其他时间相比,经前对高糖、高脂肪和/或高盐食物的渴望会增加。为了确定对高盐和/或高脂肪食物的强烈渴望是否与整个月经周期中食物偏好的变化有关,研究人员对34名体重正常、处于大学年龄的女性连续四周进行了评估,这些女性被给予添加了不同盐量(0.0、1.5和4.0克)和黄油量(3.3、10和30克)的30克空气爆米花,然后对其偏好和感官评分进行测定。此外,使用情绪状态量表(POMS)来确定整个月经周期中的情绪状态。使用三因素饮食问卷(TFEQ)评估饮食限制、去抑制和饥饿程度。爆米花样本的偏好评分以及咸味或油腻感评分均未随月经周期而变化。此外,在整个月经周期中未观察到情绪状态的差异。然而,有饮食限制的人群对爆米花样本的偏好评分明显高于无饮食限制的人群。有饮食限制的人群还认为样本的咸味明显更高,并且在POMS的紧张焦虑和抑郁沮丧子量表上的得分明显高于无饮食限制的人群。此外,每周锻炼超过3小时的女性的偏好评分明显高于每周锻炼少于3小时的女性。据推测,观察到的偏好评分因饮食限制和运动而产生的变化是对食物的认知信念差异的结果,而非生理因素的差异。
