Dietary Guidelines for Americans-Ultra Processed Study

The purpose of this project is to address the current gap in research on ultra-processed foods (UPFs) and cardiometabolic health with a feeding study that addresses the limitations of previously conducted intervention studies in matching UPF- and unprocessed- foods intervention diets for diet quality, nutrient content, and food type. Therefore, the primary objective is to evaluate diets composed primarily of ultra-processed or less processed foods that meet dietary guidelines recommendations on chronic disease risk factors. More specifically, when Dietary Guidelines for Americans (DGA)-compliant diets comprised of mostly ultra-processed and unprocessed foods (per Nova) are fed to generally healthy participants, determine whether there is an impact on: * blood pressure * fasting glucose and insulin concentrations, or * lipid panel (total cholesterol, HDL-C, LDL-C, triglycerides).
