In response to a request from Congress, the Health and Medicine Division of the National Academies of Sciences, Engineering, and Medicine conducted a study comparing the process to develop the Dietary Guidelines for Americans, 2020–2025 (DGA 2020-2025) to recommendations included in the previously published National Academies report, Redesigning the Process for Establishing the Dietary Guidelines for Americans. This report describes the findings of the committee and conclusions related to this assessment. Notably, this report does not evaluate the merits of the DGA 2020-2025 but evaluates the process by which they were created relative to the recommendations made in the previously published National Academies report.
