Environmental factors play a critical role as trigger of inflammation in inflammatory bowel disease (IBD) and nutritional factors contribute to pathology of IBD. Moreover, exclusive enteral nutrition (EEN) is now considered, as the first line induction therapy for mild to severe paediatric Crohn disease (CD) without anoperineal disease. Recently, new therapeutic nutrition protocols such as “Crohn disease exclusion diet” have been prospectively evaluated in paediatric CD patients. Some of them reported promissing results. Yet, these new therapeutic options, validated in paediatric, could also be proposed to adult patients. Overall, new nutritional approaches will require new financial resources for dietetician and therapeutic education founding.
