Summary

"This trial will compare how well two types of liquid diets work for children with newly diagnosed Crohn's disease. One group will drink a commercial formula, while the other will make a smoothie at home

Who is the study for?

This trial is for children and young adults aged 8-21 who have been diagnosed with Crohn's disease within the last two years. They must show active symptoms, as indicated by a specific activity index score (PCDAI ≥10) and elevated inflammation markers. Participants or their guardians must be able to give informed consent.

What is being tested?

The study compares traditional formula-based Exclusive Enteral Nutrition (EEN) with a whole-food based smoothie EEN in treating pediatric Crohn's disease. It will assess which method is more tolerable, effective, and how they affect life quality and gut bacteria over an 8-week period.

What are the potential side effects?

Potential side effects may include gastrointestinal discomfort such as nausea or bloating due to dietary changes. Since this involves nutrition rather than medication, severe side effects are less likely compared to drug treatments.
