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.
