Coffee and tea: a new weapon against fatty liver?
NCT ID NCT07768956
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This study tests whether adding Turkish coffee or green tea to a Mediterranean diet can reduce liver fat in people with non-alcoholic fatty liver disease (NAFLD). Participants will follow a 12-week diet plan and drink either Turkish coffee twice daily, green tea three times daily, or no extra beverage. Researchers will measure changes in liver fat, liver enzymes, and body measurements to see if these drinks offer extra benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Turkish coffee, green tea, and a Mediterranean diet
- What this could lead to
- If this works, it could point to simple dietary additions that help manage fatty liver disease and improve liver health.
- What could go wrong
- This is a small, early-stage trial, so results may not apply broadly. The effects could be modest, and the study doesn't test long-term outcomes.
