About this study

This study will compare the tolerability and efficacy of conventional formula Exclusive Enteral Nutrition (EEN) and whole-food blended smoothie EEN by enrolling a total of 60 participants with newly diagnosed pediatric Crohn's disease (CD). Participants will be provided either commercial formula or guided on the preparation of the home-blended smoothie. These participants will be given a specific recipe, blender, and be provided the food components to the smoothie. The study will total 8 weeks and will assess tolerance, clinical outcomes, stool microbiome, and quality of life.
