Redesigning the Process for Establishing the Dietary Guidelines for Americans (2017)
Chapter: Part I
Part I
This report is presented in two parts to facilitate understanding of this National Academies of Sciences, Engineering, and Medicine (the National Academies) committee’s vision and recommendations for an improved process to update the Dietary Guidelines for Americans (DGA), particularly for those readers who are already familiar with the details of the current process. Part I presents this National Academies committee’s judgments and recommendations to redesign the process to update the DGA. Part II provides a detailed description and evaluation of the process as it has been conducted in recent cycles. Part I consists of three chapters:
Chapter 2 provides this National Academies committee’s vision for how the roles and purposes of the process to update the DGA could best support development of dietary guidelines that Americans can trust and follow.
Chapter 3 presents this National Academies committee’s proposed process redesign model to help the DGA adapt to future changes in Americans’ health.
Chapter 4 suggests how the evidence base for the DGA can be strengthened. This is a critical topic given that the DGA are required to be based on the preponderance of evidence.
This National Academies committee encourages readers who would like a more in-depth description of the DGA process to turn to Part II for a full accounting of the current process, inclusive of an evaluation and key findings.
