Data analysis conducted
Review public comments and agency input
Considered each comment in relation to four criteria (briefly: relevance, importance, impact, and avoiding duplication)
Review needs of federal nutrition-related programs
Protocols created for each question
Data analysis protocols
Food pattern modeling protocols
Systematic review protocols
Data analysis—collection of analyses to describe the current health and dietary intakes of Americans
Food pattern modeling—analysis of how a change in dietary pattern affects nutrient needs
Systematic reviews—synthesizing peer-reviewed literature
Review public and agency comments on DGAC Scientific Report
Review needs of federal nutrition-related programs, previous guideline editions, and previous DGAC recommendations

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.
