Overview

Brief Summary

The goal of this pilot clinical trial is to examine how receipt of ingredients for a Mediterranean diet (with or without nutrition classes) impacts Type 2 Diabetes Mellitus risk factors among adults in the US South. The main question it aims to answer is:

- Will greater improvements in diet quality (HEI Score) and body weight be seen in the group that receives grocery delivery and nutrition classes (TK+FiM) compared to the group receiving grocery delivery only (FiM only)?

Researchers will evaluate the changes in diet quality and body weight among participants in each group to see which group experiences greater improvements.

Participants will:

  • be randomly assigned to either receive weekly grocery deliveries and attend weekly virtual nutrition classes for 4 weeks or receive weekly grocery deliveries only.
  • be asked to complete surveys/questionnaires at the baseline and 4-week timepoints in the study.
  • be asked to participate in a post-study focus group to talk about their experiences during the intervention.
