The RE-EEN Smoothie Study is recruiting patients newly diagnosed with Crohn's Disease who are interested in using diet to help achieve disease remission. The purpose of the study is to evaluate the use of a whole-food based smoothie as Exclusive Enteral Nutrition for Crohn's Disease. In this study, participants will be randomly assigned to receive either a whole-food based smoothie, or formula as Exclusive Enteral Nutrition (EEN) therapy for Crohn's Disease. Participants will work closely with the study dietician to ensure that all of their nutritional needs are met during their participation in the study.
