Food-based dietary guidelines (FBDGs) should be practical and implementable public health nutrition messages to guide the public towards food choices that support health(1). However, the relevance of FBDGs for the public has been questioned, as messaging is not always relatable, contextually and culturally appropriate, or usable for many groups(2,3). Additionally, there has been criticism around the lack of involvement of marginalised people in food policy development, further contributing to the development of guidelines that are not appropriate(4). Consumer-testing with diverse groups is important for ensuring that FBDGs are suitable for their target population. As the Australian Dietary Guidelines are currently undergoing revision and about to move into consumer-testing phases, this scoping review explores how consumer testing is incorporated into FBDG development and revision around the globe and provides insights on how consumer input influences FBDG design. Scientific literature was identified from OVID Medline, CINAHL, PubMed, Web of Science and Scopus databases using a key-word search with terms related to FBDGs and consumer-testing. Articles were screened to identify relevant studies. Grey literature was identified by desk top search, for articles that reported on consumer-testing during the process of FBDG development or revision for any country. Screening of eligible articles and data extraction of scientific and grey literature were conducted in duplicate. From 2767 titles, 17 full-text articles met the criteria, representing 10 countries. Twenty-one grey literature records were identified, representing 18 countries (a total of 22 different countries). From 142 countries for which FBDGs were identified, only 22 reported consumer-testing during guideline development or revision. Reporting varied by region, with 9 African countries represented, 6 Latin American and the Caribbean, 4 Asia Pacific countries, 2 North American, 1 Middle Eastern, and zero European. Consumer-testing was conducted using focus groups, field-test trials, surveys or through public consultation submissions. Of the 22 countries that reported consumer-testing, only 10 reported how the outcomes of consumer-testing resulted in changes to the FBDGs. Reported changes included updates to wording and imagery to improve the clarity, cultural relevance and applicability. Recommendations for improved educational materials were also noted. Consumer testing is important for ensuring FBDGs fulfill their intended role, but it is poorly reported, resulting in a lack of transparency around whether consumer-testing is done and how the feedback is used to inform guidelines. Where consumer-testing was reported, feedback informed and, at times, resulted in meaningful changes to FBDG messages. Thorough and transparent consumer-testing during the revision for the Australian Dietary Guidelines will help to ensure the updated guidelines are fit-for-purpose.
