Food Intolerance: Dietary Treatments in Functional Bowel Disorders

Currently, there is little convincing scientific evidence from well-designed trials to support the role of dietary modification or exclusions in irritable bowel syndrome (IBS). Similarly, there is an absence of conclusive data linking any dietary components directly to the pathogenesis of IBS. The role of diet, as a single modality, is unlikely to play a major role in treating IBS. Dietary modifications should be viewed as a valuable part of a multicomponent management approach in combination with other strategies such as lifestyle, behavioral, and pharmacologic therapy.
