NCT ID NCT07376226
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This study will test whether eating a diet rich in whole fruit (up to 50% of daily calories) for 17 weeks can improve blood sugar control, reduce liver fat, and lower heart disease risk in adults with type 2 diabetes who do not use insulin. Participants will eat fruit prepared in a research kitchen and track their progress. The goal is to see if a fruit-focused diet is a safe and effective way to manage diabetes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- whole fruit (fresh, dried, and frozen fruit blended into smoothies)
- What this could lead to
- If it works, this could show that a high-fruit diet helps manage blood sugar and reduce liver fat in type 2 diabetes, offering a simple dietary approach.
- What could go wrong
- This is a very small early study (25 people) with no control group, so results may not apply broadly. Eating 50% of calories as fruit may be hard to sustain and could raise blood sugar in some people.
