ClinConnect Summary

This clinical trial is exploring how a Mediterranean diet that includes baked potatoes with the skin can affect heart and metabolic health in adults who have pre-diabetes. Researchers want to find out if adding these potatoes and nutrition education can help improve blood sugar levels, heart health, and overall diet quality in participants. They will compare those who follow this enhanced diet plan to those who follow the Mediterranean diet alone to see if the addition of baked potatoes makes a difference.

To participate, you need to be between 45 and 80 years old, live in the Las Vegas/Henderson area, and meet certain health criteria, such as having a specific blood sugar level and body mass index (BMI). If you join, you'll come to the study site for screenings and regular check-ups over 12 weeks to track your health progress and receive guidance on diet. You’ll also keep a record of what you eat during this time. If you're chosen for the group that includes baked potatoes, you'll receive these potatoes every three weeks. It's important to note that some people, like those with certain health conditions or those on specific medications, won't be eligible to participate.
