Abstract (Summary)

Objective: Individuals with Celiac Disease (CD) and Non-Celiac Gluten Sensitivity (NCGS) who follow a gluten-free diet may not be aware of the different gluten-free claim labels in the marketplace today. To date, no research has determined which labels are considered most used and trusted by people with CD and NCGS. This study evaluated perceived knowledge, utility and trustworthiness of gluten-free claim labels in adults with CD or NCGS.

Methods: A three-part de-identified online survey was created using RedCapTM to assess knowledge, utility and trustworthiness of gluten-free claim labels in participants with CD and NCGS. Participants needed to be 18 years or older, understand English, live in the U.S., follow a GFD, and eat/serve packaged foods bearing a claim label. Dissemination of the survey occurred through Facebook pages and websites of the labels and gluten-free related organizations. Statistical tests included Kendall’s tau.

Results: Of the 620 participants in the survey, 339 participants completed all survey questions (55%). For participants with CD, a positive association was found between “recognition of third-party certification program” and “utility” of the Gluten-Free Certification Organization’s label (p = 0.044) and Celiac Support Association’s label (p=0.010), indicating as knowledge of these programs increase, use of the label does too. In addition, in participants with CD, a positive association was found between “recognition of parts per million of gluten” and “trustworthiness” for all of the labels, indicating as knowledge of the level of gluten allowed in a label increases, trust increases for a label. Overall, the most useful and trusted label was the Gluten-Free Certification Organization’s label.

Conclusion: Participants with CD reported more knowledge about, trust of, and use of gluten-free claim labels than participants with NCGS. The Gluten-Free Certification Organization’s gluten-free claim label was identified as the most useful and trusted by those with CD and NCGS in this study.
