Attitudes and Barriers Toward Consumption of More Plant-Based Foods Among Danish Patients with Celiac Disease

Background: Celiac disease (CeD) requires lifelong adherence to a gluten-free diet (GFD). However, there is evidence that a GFD may lead to an unhealthy cardiometabolic risk profile and potentially increase the risk of cardiovascular disease in some patients. Incorporating plant-based foods (primarily derived from plants) into a GFD may offer a solution to improve cardiometabolic health. Thus, this study aimed to identify the attitudes toward and barriers to adopting a more plant-dominant diet among Danish patients with CeD. Methods: A cross-sectional survey was distributed to 2861 members of the Danish Celiac Society. Data from 959 patients with confirmed CeD were included. Results: Most participants (58.5%) reported adapting their diet after diagnosis by combining gluten-free products with plant-based foods, while 31.2% relied solely on gluten-free replacements. Dietary adaptation was primarily shaped by the limited availability of gluten-free plant-based foods (64%), taste/texture (55%), and cost (51%). More than half of the patients (56.8%) considered ‘eating more plant-based foods’, with ‘health’ being the primary motivator (70%), followed by ‘climate’ (50%) and ‘taste’ (36%). However, several barriers to a more plant-dominant diet were identified. Most notably, ‘taste and texture’ (71%), ‘limited availability of gluten-free plant-based foods’ (68%), ‘nutritional concerns’ (56%), and ‘cost’ (54%) were reported as barriers. Conclusions: Most Danish patients with CeD were generally positive about increasing their intake of plant-based foods; however, barriers to such dietary changes remain. Ongoing follow-up, practical guidance from dietitians, and accessible evidence-based resources may help patients maintain a nutritionally balanced, plant-dominant GFD that supports long-term health.
