Effects of a Mediterranean Dietary Pattern With White Potato on Cardiometabolic Health in Adults With Pre-Diabetes
Source: ClinicalTrials.gov · Last updated 7 Oct 2026
Brief summary (registry, in English)
The goal of this clinical trial is to is to determine the effects of baked potato with the skin (BP) + nutrition education focused on adherence for a Mediterranean Dietary Pattern (MEDNE) on glycemic control, cardiometabolic health, and dietary quality in individuals with pre-diabetes from different demographic backgrounds. The main questions it aims to answer are: * Does BP+MEDNE contribute to improvements in indices of glycemic control, vascular function, blood lipids, inflammation/oxidative stress, and body composition? * Does BP+MEDNE contribute to improvements to overall dietary intake and quality? Researchers will compare BP+MEDNE to MEDNE alone to see if BP+MEDNE can improve glycemic control, cardiometabolic health, and dietary quality in individuals with pre-diabetes from different demographic backgrounds. Participants will: * Be asked to come to the study site initially for a Screening Study Visit to confirm eligibility. * Be asked to come the study site for a Pre-Baseline and Pre-12-Week Study Visit (one week prior to Baseline and 12-Week Study Visits) for placement of placement of a continuous glucose monitor and wearable devices to be removed at Baseline and 12-Week Study Visits. * Be asked to come to the study site for Baseline, 6- and 12-Week Study Visits for assessments of glycemic control and cardiometabolic health. * Be asked to complete 3-Day Food Records throughout the 12 week study period for assessment of dietary quality (5 total) * Receive pre-recorded MEDNE ( which can be accessed via computer device/ipad/smartphone) after Baseline and 6-Week Study Visits. * If randomized to the BP+MEDNE group, participants will receive pre-prepared baked potatoes with the skin for the 12-week study period (every 3 weeks) at Baseline and 6-Week Study Visits and asked to come to the study site for picking up the pre-prepared baked potatoes at weeks 3 and 9 of the study period.
