This midcourse report provides an initial assessment of how the process used to develop the Dietary Guidelines for Americans, 2020-2025 (DGA) compares to the recommendations in the 2017 National Academies report on redesigning the process for establishing the DGA. It also assesses the criteria and processes for including the scientific studies used to develop the guidelines. The scope of this study was to address the process and not the content of the guidelines.
