Abstract

Objective

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.

Design

We conducted three scenario-based experiments. In Study 1 (N = 478) and Study 2 (N = 199), we manipulated the availability of nutrition information and measured dietary restraint. Study 3 (N = 275) extended Study 2 by adding a condition where we provided reference information about recommended daily calories.

Main outcome measures

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).

Results

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.

Conclusion

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.

知情放纵：营养信息提供和饮食限制对连续食物消费决策的影响

摘要

客观的

营养和菜单标签已在全球范围内越来越多地实施。本研究考察了营养信息提供对受限制和不受限制的食客立即和随后的消费决策的影响。

设计

我们进行了三个基于场景的实验。在研究 1 ( N  = 478) 和研究 2 ( N  = 199) 中，我们操纵了营养信息的可用性并测量了饮食限制。研究 3 ( N  = 275) 通过添加一个条件扩展了研究 2，其中我们提供了有关每日推荐卡路里的参考信息。

主要观察指标

我们衡量了相对低热量和高热量替代品之间的选择（研究 1-3），并衡量了随后决定食用放纵食物的决定（研究 2 和 3）。

结果

无论饮食限制如何，营养信息通常不会影响低热量和高热量选择之间的选择。然而，在有营养信息的情况下选择高热量食物的克制饮食者表示他们会减少随后的摄入量。

结论

营养信息并不一定会减少对相对高热量食物的选择，但它可以帮助克制饮食者减少选择高热量食物后的后续摄入量。这些结果表明，尽管对选择没有直接影响，但营养和菜单标签可能会在以后使受限制的食客受益。
