The results of the present study showed that despite the theoretical discussion about the different formats’ advantages or disadvantages,11,12 overall, all formats appeared equally effective and efficient in practice. This equality of formats could also explain why previous studies comparing different formats found only small differences regarding the effectiveness of the different food guide formats.9,10 However, there were some differences between the formats that should be considered. First, there were differences regarding the effectiveness of the various formats in 3 of the 5 statements. The data thus suggest that all 3 formats have the potential to improve performance for some tasks, but less for others.
The effectiveness of a certain format also seems to depend on the task at hand, which may also explain why previous studies using different tasks or knowledge questions to assess the effectiveness of food guides showed inconsistent results regarding the superiority of 1 of the formats.
