Effects of Mediterranean Diet and Baked Potatoes on Heart and Metabolic Health in Adults with Prediabetes Aged 45 to 80

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 BPMEDNE 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.
