NCT ID NCT07625046
First seen Jun 24, 2026 · Last updated Sep 01, 2026 · Updated 4 times
Summary
This study looks at how dried figs affect blood sugar and insulin in adults with pre-diabetes. Five participants will eat figs or a calorie-matched control breakfast, and researchers will measure blood glucose, insulin, and fig polyphenol levels over 24 hours. The goal is to see if fig polyphenols can improve insulin function and help manage blood sugar.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dried figs (polyphenols)
- What this could lead to
- If it works, this could suggest that eating dried figs helps manage blood sugar and insulin levels in people with pre-diabetes.
- What could go wrong
- This is a very small, early-stage trial with only 5 participants, so results may not apply widely. It is also not designed to prove long-term benefits or safety.
