BACKGROUND & AIMS
Patients with inflammatory bowel diseases avoid a variety of foods. However, it remains unclear how this behavior varies across patients. This cross-sectional study investigated how the food avoidance pattern in inflammatory bowel disease varies according to disease's activity, disease's subtype, Crohn's location, and prior history of bowel resection, strictures, and fistulae.

METHODS
Outpatients with Crohn's disease (n = 173) and ulcerative colitis (n = 72) reported which food they avoid when they perceive they are in remission or in active disease using a list of 82 food items classified in 10 categories. Medical charts were reviewed for patients' characteristics. Linear regression analyses were used to compare food exclusion rates between patients' subgroups and food categories.

RESULTS
During remission, food exclusion rates varied from 1 to 39%. Most avoided foods were those with capsaicin, meat alternatives, and raw vegetables. Overall, food exclusion rates were 38% higher in Crohn's disease than ulcerative colitis (P < 0.001), and 50% higher in stricturing than non-stricturing Crohn's disease (P < 0.001). During active disease, food exclusion rates were 69% higher than in remission (P < 0.001). Similar differences between subgroups were again observed during active disease though less noticeable than in remission. No association was found with other disease characteristics. Avoided foods were very similar across patients except for alcoholic beverages and foods rich in dietary fibers/residue, which were avoided more specifically during active disease and in Crohn's disease, respectively.

CONCLUSIONS
Food avoidance is common among patients with inflammatory bowel diseases, and most particularly in those with stricturing Crohn's disease. Specificities in avoidance pattern suggest that the clinical response to dietary restrictions may differ according to the disease's characteristics.
