Optimizing The Process For Establishing The Dietary Guidelines For Americans

Federal guidance on nutrition and diet is intended to reflect the state of the science and deliver the most reliable recommendations possible according to the best available evidence. This guidance, updated and presented every 5 years in the Dietary Guidelines for Americans (DGA), serves as the basis for all federal nutrition policies and nutrition assistance programs, as well as nutrition education programs. Despite the use of the guidelines over the past 30 years, recent challenges prompted Congress to question the process by which food and nutrition guidance is developed. This report assesses the process used to develop the guidelines; it does not evaluate the substance or use of the guidelines. As part of an overall, comprehensive review of the process to update the DGA, this first report seeks to discover how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints for the purpose of informing the 2020 cycle.

What foods should Americans eat to promote their health, and in what amounts? What is the scientific evidence that supports specific recommendations for dietary intake to reduce the risk of multifactorial chronic disease? These questions are critically important because dietary intake has been recognized to have a role as a key determinant of health. As the primary federal source of consistent, evidence-based information on dietary practices for optimal nutrition, the Dietary Guidelines for Americans (DGA) have the promise to empower Americans to make informed decisions about what and how much they eat to improve health and reduce the risk of chronic disease. The adoption and widespread translation of the DGA requires that they be universally viewed as valid, evidence-based, and free of bias and conflicts of interest to the extent possible. However, this has not routinely been the case. A first short report meant to inform the 2020 review cycle explored how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints. This second and final report recommends changes to the DGA process to reduce and manage sources of bias and conflicts of interest, improve timely opportunities for engagement by all interested parties, enhance transparency, and strengthen the science base of the process.

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.

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.

America's leading nutritionist exposes how the food industry corrupts scientific research for profit Is chocolate heart-healthy? Does yogurt prevent type 2 diabetes? Do pomegranates help cheat death? News accounts bombard us with such amazing claims, report them as science, and influence what we eat. Yet, as Marion Nestle explains, these studies are more about marketing than science; they are often paid for by companies that sell those foods. Whether it's a Coca-Cola-backed study hailing light exercise as a calorie neutralizer, or blueberry-sponsored investigators proclaiming that this fruit prevents erectile dysfunction, every corner of the food industry knows how to turn conflicted research into big profit. As Nestle argues, it's time to put public health first. Written with unmatched rigor and insight, Unsavory Truth reveals how the food industry manipulates nutrition science--and suggests what we can do about it.
