Dietary Guidelines for Americans-Ultra Processed Study

The purpose of this research is to test how processing food can affect how one's body responds to it.

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).
