Many IBD patients are keen to modify their diet to better manage their disease. However, little or no dietary guidance is offered to IBD patients or is not comprehensive and lacks practical resources to implement and sustain the modification. Up to 70% of IBD patients self-prescribe dietary restrictions with demonstrated risk of nutrient deficiencies. There is currently no comprehensive IBD dietary intervention presented in a customizable, easy-to-follow protocol format. To meet this need, we developed and tested a full-featured online version of an effective IBD dietary intervention.
