What this trial studies

This study compares the tolerability and efficacy of conventional formula Exclusive Enteral Nutrition (EEN) with a whole-food blended smoothie EEN in pediatric patients newly diagnosed with Crohn's disease. A total of 60 participants aged 8 to 21 will be enrolled and provided either a commercial formula or guided on how to prepare a home-blended smoothie using specific recipes and ingredients. The study will last for 8 weeks, during which it will assess tolerance, clinical outcomes, stool microbiome, and quality of life among participants.

Who should consider this trial

Good fit: Ideal candidates are children aged 8 to 21 who have been diagnosed with Crohn's disease within the last 24 months and show active disease symptoms.

Not a fit: Patients with a history of surgery for Crohn's disease or those who have previously used biological medications or dietary therapies for Crohn's may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more tolerable and effective nutritional approach for managing Crohn's disease in children.

How similar studies have performed: While there is limited data on the specific approach of using whole-food smoothies, similar studies on dietary interventions in Crohn's disease have shown promising results.
