Crohn's disease (CD) is a well-known subset of inflammatory bowel disease (IBD) that results in patchy inflammation through the entire thickness of the bowel wall, with the ability to target virtually any part of the gastrointestinal tract, but most commonly affecting the area between the ileum and the cecum. While a bacterial origin of Crohn's is well speculated, it is difficult to pinpoint what drives inflammation in these subjects, particularly the flare-ups or the sudden symptomatic intensification or recurrence. This review aims at tracing the etiology of CD back to diet, particularly fried foods, a known aggravator of symptoms. Based on the reactions that frying entails, the chemical composition of the food is altered in ways that can lead to maldigestion and inflammation. Current evidence suggests a direct dietary role in the inflammation underlying CD or the flare-ups. The presented review focuses on an underresearched, yet, very applicable topic. We suggest that emphasis should be put on dietary alteration as a means of treatment for patients with CD to supplement current therapy for optimal results. With the widespread popularity of fried foods, it is important to raise awareness about the potential negative outcomes that are prevalent worldwide.
