研究表明，食品营销人员使用的微妙的健康声明影响了摄入前的预期，但没有研究调查过它们如何影响个人在吃完一顿饭后的饱腹感，以及这种饱腹感如何随着对食物味道的重视而变化。在两个实验中，我们评估了将意大利面沙拉标记为“健康”或“丰盛”如何影响自我报告的饱腹感、消费量以及随后对另一种食物的消费。使用方差分析，研究1表明，那些认为对味道不重视的人吃得更少，但当一份沙拉被贴上“丰盛”而不是“健康”的标签时，他们的饱腹感还是一样的。相比之下，对于口味更重要的人来说，消费和自我报告的饱腹感是相关的，当沙拉被标记为“丰盛”而不是“健康”时，两者都更高。研究2强调了味觉的重要性，而不是衡量它，并在消费上重复了这些发现，但在自我报告的饱腹感上却没有。在两项研究中，对其他食物的摄入都没有影响。总的来说，我们的发现增加了早期关于健康标签影响的研究，表明微妙的食物描述也会影响摄入后的饱腹感，但影响的方向取决于味道的重要性以及选择直接或间接的饱腹感测量方法。(C) 2013 Elsevier Ltd.版权所有。
Research has shown that subtle health claims used by food marketers influence pre-intake expectations, but no study has examined how they influence individuals' post-consumption experience of satiety after a complete meal and how this varies according to the value placed on food taste. In two experiments, we assess how labeling a pasta salad as "healthy" or "hearty" influences self-reported satiety, consumption volume, and subsequent consumption of another food. Using MANOVA, Study 1 shows that individuals who report low taste importance consume less yet feel just as satiated when a salad is labeled "hearty" rather than "healthy." In contrast, for individuals with higher taste importance, consumption and self-reported satiety are correlated and are both higher when a salad is labeled as "hearty" versus "healthy." Study 2 primes taste importance, rather than measuring it, and replicates these findings for consumption, but not for self-reported satiety. There was no effect on the consumption of other foods in either study. Overall, our findings add to earlier work on the impact of health labels by showing that subtle food descriptions also influence post-intake experiences of satiety, but that the direction of the effects depends on taste importance and on the selection of direct or indirect measures of satiety.
