Dietary intake of patients with inflammatory bowel disease aligns poorly with traditional Mediterranean diet principles.

Aim: Previous research has shown that individuals with inflammatory bowel disease avoid specific food items, such as fibre rich foods, in order to manage symptoms. Dietary fibre and the traditional Mediterranean diet are both associated with reduced mucosal and systemic inflammation, gut barrier integrity, and microbiota diversity. There is limited data on the diet composition of individuals with inflammatory bowel disease. The aim of this study was to evaluate how it compares to the traditional Mediterranean diet and national dietary guidelines. Methods: Outpatients with inflammatory bowel disease were recruited to the study between February and August 2019. Demographic and medical information was obtained for consenting participants. All participants completed a dietary assessment of usual intake (24‐h diet recall and 17‐point ready reckoner) from which a Mediterranean diet adherence score was calculated. Dietary intake of core food groups was compared to the recommended number of serves outlined in the Australian Guide to Healthy Eating. Results: 100 participants were recruited. The mean Mediterranean diet adherence score was 5.1 ± 1.3 (maximum 14 points), 4% of participants scored ≥9 (commonly agreed criteria for Mediterranean diet adherence). Participants also consumed considerably less grains and vegetables than national dietary guidelines recommendations. Conclusions: The diet of outpatients with inflammatory bowel disease did not align with Mediterranean diet characteristics. Participants consumed significantly less grains and vegetables than national guidelines, suggesting a low fibre intake. These findings suggest that dietary interventions focusing on improving the diet of individuals with inflammatory bowel disease to align with Mediterranean diet characteristics are warranted.
