Mediterranean diet tested as Add-On for spine arthritis
NCT ID NCT07170384
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether a Mediterranean diet can lower disease activity and improve quality of life in 110 people with axial spondyloarthritis (a type of arthritis affecting the spine) who are already on biologic therapy. Participants will either follow a structured Mediterranean diet or receive general healthy eating advice for 3 months. Researchers will measure changes in inflammation, pain, fatigue, and sleep.
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 it works, this could show that a Mediterranean diet helps reduce inflammation and improve symptoms in people with axial spondyloarthritis, potentially adding a simple lifestyle tool to standard care.
- What could go wrong
- This is a small, early-stage trial with only 110 participants and a short 3-month follow-up. Diet changes can be hard to stick with, and results may not apply to everyone.
