Abstract

Objectives

Myths about diet and nutrition are widespread and may seriously impact health and well-being. This study tests whether texts in a truth sandwich format, that is, texts presenting two blocks of factual, correcting information around a text block listing a myth and identifying it as false, are effective in reducing agreement with a range of nutrition myths.

Design

Prestudy: observational survey; main study: 4 Text × 6 statement mixed experimental design.

Methods

Out of 13 nutrition myths that were presented to 58 participants in a prestudy, the six most prevalent myths were selected for the main study. In the preregistered main study, 302 participants were randomly assigned to either reading one of three texts in the truth sandwich format addressing a nutrition myth or reading a text about healthy eating (control condition) before rating their agreement with a total of six nutrition myths.

Results

Participants agreed less with the specific myth targeted by the truth sandwich text, while controls were not differentiating between them.

Conclusions

Thus, truth sandwiches are effective in reducing agreement with myths and can be harnessed to promote evidence-based dietary practices to promote health in the population.

揭开营养神话：“真相三明治”文本格式的实验测试。

目标：关于饮食和营养的神话很普遍，可能会严重影响健康和幸福。这项研究测试了真理三明治格式的文本，即呈现两个事实块的文本，围绕一个列出神话的文本块更正信息并将其认定为虚假的文本，是否能有效减少与一系列营养神话的一致性。设计：预研：观察性调查；主要研究：4个文本× 6陈述混合实验设计。方法：在一项研究前向58名参与者提出的13个营养神话中，选择六个最普遍的神话作为主要研究。在预先注册的主要研究中，302名参与者被随机分配阅读三篇关于营养神话的真理三明治形式的文本中的一篇，或者阅读一篇关于健康饮食（对照条件）的文本，然后对他们对总共六个营养神话的一致性进行评分。结果：参与者不太同意真相三明治文本所针对的特定神话，而对照组则没有区分他们。结论：因此，真理三明治在减少与神话的一致性方面是有效的，可以用来促进循证饮食实践，以促进人群健康。
