Diet and Nutrition in Inflammatory Bowel Disease: A Review of the Literature.

Diet is thought to contribute to the development of inflammatory bowel disease (IBD) and may act as a mediator of inflammation in patients with IBD. Patients commonly associate their diet with symptoms and inquire about dietary modifications to manage their IBD. Without clinical guidelines and well-established nutritional data, healthcare providers managing patients with IBD may find it difficult to provide recommendations. Strong evidence for enteral nutrition, particularly in the pediatric population, has been established in Crohn's disease (CD) as a therapeutic option. Enteral nutrition may also serve as an adjunct to an exclusion diet. Recent studies such as the randomized trial comparing the Specific Carbohydrate Diet to a Mediterranean Diet in CD patients provide additional insights in forming dietary plans. A low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet in quiescent IBD and an anti-inflammatory diet have also been explored as adjunctive therapies. In this review, we discuss the latest evidence for the role of diet in IBD both as a therapeutic modality and as an opportunity to provide patient-centered care.
