Effects of a Mediterranean Dietary Pattern With White Potato on Cardiometabolic Health in Adults With Pre-Diabetes

Summary

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.

Interventions

• Behavioral
  Mediterranean Diet Nutrition Education

  Participants randomized to receive the Mediterranean Diet Nutrition Education will receive a pre-recorded education session (lasting approximately 1 hour) they can watch at home after their Baseline and 6-Week Study Visits, which will be created by the PI and Co-I's of the study (who are comprised of Professors who are either Registered Dietitian credentialed or have experience with creating nutrition/physical activity programs), including an explanation of the principles and components of a Mediterranean dietary pattern and its benefits, guidance on recommended intake of various food groups, budget-friendly strategies for incorporation, supporting resources (educational materials and online tools), and techniques for overcoming barriers to following a Mediterranean dietary pattern. Additional educational materials will be provided to participants through computer or web-based sources.

• Behavioral
  Mediterranean Diet Nutrition Education with Baked White Potato

  Participants randomized to receive the Mediterranean Diet Nutrition Education with Baked White Potatoes will similarly receive a pre-recorded education session (lasting approximately 1 hour) they can watch at home after their Baseline and 6-Week Study Visits (same as the Mediterranean Diet Nutrition Education group). They will also receive will 100 g roasted white russet potatoes with the skin and will be asked to consume the regimen as a part of their meals (breakfast, lunch, dinner) or as a snack throughout the day to contribute to a balanced meal plan. The baked white potato regimen will be pre-portioned (in 100g amounts), stored in the freezer and given in freezer-microwave safe containers. The baked white potato regimen is approximately 100 kilocalories, 22g carbohydrates, and 0.2g of fat . In order to increase participants' compliance, they will be informed of a variety of ways to consume the baked white potato regimen.
