Abstract
Inflammatory bowel disease (IBD) is characterized by the presence of gastrointestinal inflammation, that in some individuals leads on to complications, including strictures. IBD can be associated with significant morbidity with disruption of daily activities. Although the precise cause of IBD is unknown, epidemiologic studies indicate that diet is one contributory factor. Furthermore, various specific nutritional interventions have roles in the management of IBD. While the contribution of the Mediterranean diet (MedDiet) to the development or management of IBD has not yet been clearly delineated, available data are generally supportive. The MedDiet includes the consumption of a pattern of particular foods, such as plentiful vegetables, fruit, seafood, and olive oil, along with lifestyle features. Adherence to a MedDiet is associated with enrichment of beneficial components of the intestinal microbiome and enhanced barrier function: outcomes that are likely beneficial to individuals with IBD. The focus of this review was to highlight the evidence for the MedDiet in the setting of IBD, whilst giving an overview of the underlying health impacts of the MedDiet and the putative mechanisms of this dietary approach.
