How nutrition information frame affects parents’ perceptions of restaurants: The moderating role of information credibility

Adding easy-to-read information on menus is recommended for customers’ healthy food selections. But what format yields the best outcomes for restaurateurs has not been investigated. We use the emphasis framing effect as a theoretical lens to examine how the credibility of nutrition information affects parents’ perceptions of restaurant healthfulness and trustworthiness when exposed to two nutrition information frames on children's menus: numeric values only and numeric values with low-calorie symbols. The results of the experimental study show that parents who do not perceive nutrition information as being highly credible perceive restaurants providing numerical values only as more healthful and trustworthy. However, parents who do perceive nutrition information as being highly credible perceive restaurants as more healthful and trustworthy when both numeric values and low-calorie symbols are presented and have more positive perceptions overall. We advise restaurateurs to increase nutrition information credibility and provide additional easy-to-read information to elicit more positive perceptions.
