Thanks for your interest in the Dietary Guidelines: 3 Diet Patterns Study. This study is a 12 month intervention examining how three different dietary patterns [1) Healthy U.S.-style Eating Pattern (US), 2) Healthy Mediterranean-Style eating Pattern (Med), and 3) Healthy Vegetarian Eating Pattern (Veg)] impact dietary quality and Type 2 Diabetes Mellitus (T2DM) risk factors among African Americans (AAs). Our study will recruit AA adults (n=66) with overweight/obesity and ≥ three T2DM risk factors to participate and be randomized to follow one of the three diet groups. Healthy US diet
A Healthy US diet contains low-fat meat, fish, or poultry, low-fat dairy and eggs. It also contains plant foods such as fruits, vegetables, whole grains, and legumes/beans.
Meal examples include Brown rice with sizzling chicken and vegetables, chicken and dumpling soup, Easy oven fish with spinach basil dipping sauce & spiced apples, Egg over kale and sweet potato grits, and Grilled cheese with peaches.
Mediterranean diet
A Mediterranean diet includes all food groups and emphasizes vegetables, fruit, grains, beans, and dairy. The diet also includes some red meat, fish, and nuts/seeds, and vegetable oils.
Meal examples include Braised chicken thighs with spinach, Greek pork chops, Grilled lamb salad, Tuna salad sandwich, and Spaghetti and spinach pesto.
Vegetarian diet
A Vegetarian diet does not contain any meat products (no red meat, fish, or poultry) but emphasizes plant-based foods, such as fruits, vegetables, whole grains, and legumes/beans as well as eggs and low-fat dairy products.
Meal examples include Veggie omelet, Pizza topped with vegetables, Cheesy veggie lasagna, Tofu broccoli stir-fry, and Spicy bean burritos.
You do not have a choice in which diet you are assigned and therefore, must be comfortable with all three of the dietary choices.You will receive nutrition classes, cooking instructions, recipes, and supporting materials on the dietary approach you are assigned to follow. All the diets are safe and have shown to be effective ways to assist with achieving a healthy weight and helping reduce T2DM risk factors. Before you start the study, you will come for a virtual pre-orientation meeting on zoom followed by an in-person survey collection meeting at the University of South Carolina. University COVID protocol will be followed and masks will be required. There, you will learn more about how to do the study, you can ask questions, and you can complete a consent form to continue enrollment into the study. You will then complete a clinical lab assessment visit (in-person) where we will obtain your weight, height, blood pressure, waist and hip circumference, and hemoglobin A1c (finger stick). COVID protocol will be followed and masks will be required. You will then learn about the diet you are assigned to follow. You will follow your assigned diet for 12 months. You will receive support throughout those 12 months and specifically, you'll attend in-person group classes weekly for 6 months and then virtually (by Zoom) for the next 6 months. You will attend clinical lab assessment visits again at the 6 and 12 month period. You'll receive up to $100 for completing both 6 month, and 12 month questionnaires and clinical lab assessments.
