NCT ID NCT07223255
First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study looks at whether a Mediterranean diet can improve gut health in children with cystic fibrosis. Twenty kids aged 3 and older will follow this diet for 6 months. Researchers will check changes in gut bacteria and inflammation markers. The goal is to offer better diet advice for families.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mediterranean diet
- What this could lead to
- If successful, this could provide clearer dietary guidance for children with cystic fibrosis, potentially improving gut health and reducing inflammation.
- What could go wrong
- This is a very small, early study with only 20 participants and no control group. Results may not apply to all children with CF, and diet adherence can be challenging.
