Background: Inflammatory bowel disease (IBD) is known for its episodic relentless course of gastrointestinal symptoms. There are two major clinically defined forms of inflammatory bowel disease (IBD), Crohn's disease (CD) and Ulcerative colitis (UC). It's associated with chronic remittent or progressive inflammatory conditions that may affect the entire gastrointestinal tract and the colonic mucosa, respectively. A lot of literatures have been done to assess the role of diet in IBD management, prevention, and control, as a result, we will review the articles that investigated the diet role in IBD, and clarify the new progress that have been done, which will help the patients and the physicians in managing, and prevention of the acute attacks.
Objectives: In this paper we aimed to present the role of diet and nutritional substances in the management and prevention of inflammatory bowel disease.
Methods: PubMed database was used for articles selection, and the following keys used in the mesh ("Crohn Disease"[Mesh]) AND ("Colitis, Ulcerative/diet therapy"[Mesh] OR "Colitis, Ulcerative/prevention and control"[Mesh] OR "Colitis, Ulcerative/therapy"[Mesh]) AND "Inflammatory Bowel Diseases"[Mesh]. Conclusion: patients with IBD should increase their fiber intake in their diet, and take vitamin D supplement. Also, introduction of eicosapentaenoic acid (EPA) in a free fatty acid form (EPA-FFA) into their diet is helpful. However, the overall benefit of diet in this prevalent disease still need more research looking into the variable dietary regimens that can be given in this special population.
