Dietary behaviour, attitude and food perceptions of patients with ulcerative colitis – An observational study

Background: Dietary knowledge, perception and practices may have a role in determining the nutritional status of patients with inflammatory bowel disease (IBD). However, the assessment of these patterns has infrequently been done in developing countries. We aimed to evaluate patients with ulcerative colitis (UC) about their dietary beliefs, practices and changes after the diagnosis. Methods: We conducted a cross-sectional survey among patients with UC at a tertiary care centre in North India. Apart from clinical details, we collected information about dietary beliefs, sources of information, dietary practices and changes after the diagnosis of UC. The information was collected using a designed and pretested survey questionnaire. Results: We included 93 patients with a mean age of 40.6 ± 13.3 years and 49 (52.7%) were men. A majority of patients felt that diet had an important role in the causation of IBD (86%, n = 80) and triggering relapses (86%, n = 80). A total of 94.6% of patients ( n = 88) felt that certain foods (especially spicy and fatty food and milk) items increased the symptoms of IBD. Patients felt that some food items (yogurt and buttermilk) improved the symptoms. A total of 96.8% of patients ( n = 90) changed their diet in some form (commonly, restriction of milk products and outside food), 64% of patients ( n = 60) deprived themselves of their favourite food after diagnosis, 80.6% of patients ( n = 75) felt a need for additional dietary advice. Regular milk intake was seen more often by patients in remission than those with active disease in IBD (36/47 (76.6%) vs 7/15(46.6%), p = 0.03). Conclusion: Most patients believe that diet has an important role in the causation, relapses and treatment of UC. Patients also felt the need for more information regarding diet in IBD.
