Dietary factors have been linked to the development and symptoms of inflammatory bowel disease. However, little is known about the dietary practices of these patients after being diagnosed and what factors shape those practices. This article reports the findings of a naturalistic inquiry that explored the experience of dietary practices of Chinese patients with inflammatory bowel diseases. Purposive sampling was used and in-depth interviews were conducted with 17 patients with inflammatory bowel disease. Analysis of the transcribed data is presented thematically. Five themes were derived: (a) seeking dietary information, (b) testing out, (c) modifying diet, (d) barriers to diet modification, and (e) fear and stress. Understanding the dietary practice of patients with inflammatory bowel disease from the perspective of those diagnosed is a first step in attempting to assist them with diet management. Healthcare professionals should encourage patients to report diet modification and be aware of both personal and environmental barriers of diet modification.
