What this Trial Is About
This research aims to understand the effects of adding baked potatoes with the skin (BP) to a Mediterranean Diet Nutrition Education (MEDNE) program on blood sugar control, heart and metabolic health, and diet quality in adults with pre-diabetes from diverse backgrounds. The study will compare the combined BP+MEDNE approach with MEDNE alone to see if the addition of baked potatoes improves these health markers. Researchers will recruit adults aged 45 to 80 years with pre-diabetes for this 12-week randomized controlled trial. Participants will be randomly assigned to one of two groups: one receiving only Mediterranean Diet Nutrition Education through pre-recorded sessions, and the other receiving the same education plus pre-prepared baked white potatoes with skin to eat regularly. The potatoes are provided every three weeks during the study. Both groups will receive education after Baseline and 6-Week visits, and those in the potato group will pick up their potatoes at the study site at Baseline, Week 3, Week 6, and Week 9. Throughout the study, participants will attend multiple visits for assessments including blood sugar and insulin levels, blood pressure, arterial stiffness, body measurements, dietary intake, physical activity, sleep quality, and nutrition knowledge. They will wear devices to monitor glucose and activity one week before Baseline and 12-Week visits. Dietary records will be collected five times during the study. Researchers will measure changes in blood sugar, heart health markers, diet quality, and body composition to evaluate the effects of the interventions.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 12 weeks
Participants undergo baseline assessments including blood glucose monitoring, physical activity and sleep pattern assessments, vascular and body composition measurements, blood draws, and dietary assessments. After baseline assessments, participants begin either Mediterranean Diet Nutrition Education with or without baked white potatoes.
3 visits (Baseline, 6 weeks, and 12 weeks, all in-person)
Duration - 1 week periods before Baseline and 12-Week visits
Participants wear a continuous glucose monitor and physical activity/sleep tracking devices for one week before the Baseline and 12-Week Study Visits to assess real-time blood glucose levels, physical activity, and sleep patterns.
2 visits for device placement (1 week before Baseline and 12-Week visits) and 2 visits for removal during Baseline and 12-Week visits
Duration - 13 weeks
Participants complete three-day food records at home using a web-based tool at pre-Baseline and weeks 1, 4, 8, and 12 to assess dietary intake and quality.
