Summary

This study looks at whether adding baked potatoes (with skin) to a Mediterranean diet can improve blood sugar control, blood pressure, and cholesterol in adults aged 45-80 with pre-diabetes. Sixty participants will either get diet education alone or education plus pre-prepared baked potatoes for 12 weeks. Researchers will measure changes in HbA1c, fasting glucose, insulin, and other heart health markers.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: baked potato with skin and Mediterranean diet nutrition education
What this could lead to: If it works, this could show that including white potatoes in a healthy diet helps manage blood sugar and reduce heart disease risk in people with pre-diabetes.
What could go wrong: This is a small, early-stage trial (60 people) testing a dietary change, not a drug. Results may not apply to everyone, and the effect may be modest.
