Abstract

Background: Inflammatory bowel diseases (IBD), specifically Crohn's disease and ulcerative colitis, are multifactorial conditions. Genetic and behavioral factors are associated with disease development and influence its progression. It is known that diet plays a role in this pathogenic process.

Objective: to position nutritional and dietary factors in the management of IBD.

Methods: This consensus was developed by nutritionists, gastroenterologists, and colorectal surgeons, members of GEDIIB (Brazilian Organization for Crohn's disease and colitis). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All recommendations and statements were endorsed by stakeholders and IBD experts in a modified Delphi panel, achieving a consensus rate of at least 80%.

Results and conclusion: the recommendations were directed according to disease activity and severity. Nutritional screening and diagnosis, nutritional therapy in the active and remission phases of the disease, dietary management and exclusion diets, and supplementation were addressed. The consensus is targeted at nutritionists, general practitioners, gastroenterologists, and surgeons interested in managing adults with IBD. It supports decision-making by health insurance companies, regulatory agencies, and health institutional managers.
