Nutrition and menu labelling have been increasingly implemented worldwide. This research examines the effect of nutrition information provision on the immediate and subsequent consumption decisions of restrained and unrestrained eaters.
We conducted three scenario-based experiments. In Study 1 ( = 478) and Study 2 ( = 199), we manipulated the availability of nutrition information and measured dietary restraint. Study 3 ( = 275) extended Study 2 by adding a condition where we provided reference information about recommended daily calories.
We measured choices between relatively low-calorie and high-calorie alternatives (Studies 1-3) and measured a subsequent decision to consume indulgent food (Studies 2 and 3).
Nutrition information did not generally affect choices between low-calorie and high-calorie options, irrespective of dietary restraint. However, restrained eaters who chose a high-calorie option in the presence of nutrition information indicated they would reduce subsequent intake.
Nutrition information does not necessarily reduce the choice of relatively high-calorie food, but it can help restrained eaters reduce subsequent intake after a high-calorie choice. These results suggest that despite not having an immediate effect on choices, nutrition and menu labelling may benefit restrained eaters at a later time.
营养和菜单标签在全球范围内的应用日益广泛。本研究探讨了提供营养信息对节制饮食者和非节制饮食者即时及后续消费决策的影响。
我们进行了三项基于情景的实验。在研究1（n = 478）和研究2（n = 199）中，我们操纵了营养信息的可得性并测量了饮食节制程度。研究3（n = 275）在研究2的基础上增加了一个条件，即提供每日推荐卡路里的参考信息。
我们测量了在低热量和高热量替代品之间的选择（研究1 - 3），并测量了后续食用放纵性食物的决策（研究2和3）。
无论饮食节制程度如何，营养信息一般不会影响低热量和高热量选项之间的选择。然而，在有营养信息的情况下选择高热量选项的节制饮食者表示他们会减少后续摄入量。
营养信息不一定会减少相对高热量食物的选择，但它可以帮助节制饮食者在做出高热量选择后减少后续摄入量。这些结果表明，尽管营养和菜单标签对选择没有即时影响，但可能会在之后对节制饮食者有益。
