Introduction: Inflammatory Bowel Disease (IBD) carries a significant burden on an individual’s quality-of-life and on the healthcare system. The majority of patients use dietary modifications to manage their symptoms, despite limited research to support these changes. There is emerging data that a plant-based diet will be of benefit to IBD patients. Areas covered: A literature review on the pathogenesis and potential benefits of dietary management of IBD. Expert opinion: A Westernized diet has been associated with IBD risk and relapse; hence a plant-based diet may be of benefit to IBD patients through reducing inflammation and restoring symbiosis. Dietary therapy can be an important adjunct therapy, however, better quality studies are still required.
