Mediterranean Diet and Potatoes for Prediabetes

This study is looking at how a Mediterranean Diet, with or without baked white potatoes, affects heart and metabolic health in adults with prediabetes. Researchers want to see if these diets can improve blood sugar control (measured by HemoglobinA1c, blood glucose, and insulin levels), blood pressure, and cholesterol. You might be eligible if you are 45-80 years old, live in the Las Vegas/Henderson, NV area, and have prediabetes (HbA1c between 5.7-6.4%). The study aims to enroll 60 participants. The current recruitment status is unclear.

Study design
This is a randomized controlled trial involving 60 adults with prediabetes. Participants will be randomly assigned to one of two groups.
What's involved
You would participate in a 12-week study, which includes baseline, 6-week, and 12-week study visits. You would also watch pre-recorded nutrition education sessions.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoints are measured at 12 weeks, which suggests the study duration for participants is 12 weeks.
