Crohn's Disease Remission with a Plant-Based Diet: A Case Report

Crohn's disease (CD) is a form of chronic inflammatory bowel disease (IBD). The etiology of CD is thought to be multi-factorial; genetic factors, dietary and environmental exposures, immune events, and dysfunction of the gut microbiome are all though to play a role. The prevalence of CD is increasing globally and is higher in countries with a Westernized diet and lifestyle. Several human trials have demonstrated that plant-based dietary therapies may have utility in both the treatment of acute CD flares and the maintenance of remission. This case study describes a young adult male with newly diagnosed CD who failed to enter clinical remission despite standard medical therapy. After switching to a diet based exclusively on grains, legumes, vegetables, and fruits, he entered clinical remission without need for medication and showed no signs of CD on follow-up colonoscopy.
