The Dietary Guidelines for Americans (DGA) aim to prevent chronic disease, ensure nutritional sufficiency for all Americans, and accommodate gender, age, and metabolic health. The process to establish the advisory committee for the DGA and the development of the guidelines is complex. This study assessed how the committee selection process can be improved to provide more transparency, eliminate bias, and include a range of viewpoints. It also evaluated the compilation and utilization of the Nutrition Evidence Library (NEL) and other external systematic reviews, focusing on whether previous systematic reviews and data analysis were rigorous by objective scientific standards.

Description
An ad hoc committee will undertake an 18-month study to review the entire process used to establish the Advisory Committee for the Dietary Guidelines for Americans (DGA) and the subsequent development of the DGA, most recently revised pursuant to section 301 of the National Nutrition Monitoring and Related Research Act of 1990 (7 U.S.C. 5341). The committee will review and assess the evidence and carry out an analysis of each of the following:
(1) How the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints;
(2) How the Nutrition Evidence Library (NEL) is compiled and utilized, including whether NEL reviews and other systematic reviews and data analysis are conducted according to rigorous and objective scientific standards;
(3) How systematic reviews are conducted on long-standing DGA recommendations, including whether scientific studies are included from scientists with a range of viewpoints; and
(4) How the DGA can better prevent chronic disease, ensure nutritional sufficiency for all Americans, and accommodate a range of individual factors, including age, gender, and metabolic health.
The committee will produce a short report that includes a review of question 1 and, as needed, recommendations based on existing best practices for selecting a scientific advisory committee to inform development of the DGA. A final report will be produced that includes the committee's review of questions 2-4 and, as needed, recommendations based on existing practices for: conducting and/or including rigorous and objective nutrition systematic reviews and other data analyses to support the development of the DGA; supporting an expanded lifespan approach, specifically dietary guidance for infants up to 24 months and pregnant women (per the Agricultural Act of 2014); effectively applying the DGA to prevent diet-related chronic disease in the U.S. using existing implementation and evaluation frameworks; and identifying the role of the DGA in coordinating with and supporting nutrition guidance for disease treatment (that may also address age, gender, metabolic health, and nutritional sufficiency) developed by other Federal agencies. The committee's recommendations will conform to the specifications of the National Nutrition Monitoring Act (NNMRRA), Federal Advisory Committee Act, Data Quality Act, and align with the current infrastructure, availability of resources, and collaborative relationships led by the USDA-Center for Nutrition Policy and Promotion and HHS Office of Disease Prevention and Health Promotion. The committee will not conduct systematic reviews of nutrition science, nor evaluate the content or scientific justification of current or previous editions of the DGA.

Conflict of Interest Disclosure
Waiver for Disclosed Conflict of Interest: Barbara Schneeman, Ph.D.
In accordance with Section 15 of the Federal Advisory Committee Act, the โAcademy shall make its best efforts to ensure that no individual appointed to serve on [a] committee has a conflict of interest that is relevant to the functions to be performed, unless such conflict is promptly and publicly disclosed and the Academy determines that the conflict is unavoidable.โ A conflict of interest refers to an interest, ordinarily financial, of an individual that could be directly affected by the work of the committee. As specified in the Academy's policy and procedures (http://www.nationalacademies.org/coi/index.html), an objective determination is made for each provisionally appointed committee member whether or not a conflict of interest exists given the facts of the individual's employment and the task being undertaken by the committee. A determination of a conflict of interest for an individual is not an assessment of that individual's actual behavior or character or ability to act objectively despite the conflicting interest.
We have concluded that for this committee to accomplish the tasks for which it was established, its membership must include, among others, at least one person who has knowledge and expertise in federal nutrition program planning relevant to the Dietary Guidelines for Americans and an understanding of the practical impact on the food and agriculture industries of aligning federal nutrition assistance programs with the Dietary Guidelines.
To meet this expertise and experience, Dr. Barbara Schneeman is proposed for appointment to the committee even though we have concluded that she has a conflict of interest because she serves on two scientific advisory councils in the food and agriculture industries.
As described in Dr. Schneemanโs biographical summary, she has extensive experience in federal nutrition program planning. She has been a member of the Dietary Guidelines Advisory Committee, served as Assistant Administrator for Nutrition in the Agricultural Research Service of USDA, and was an inter-governmental reviewer of the Dietary Guidelines while serving as the Director of the Office of Nutrition, Labeling, and Dietary Supplements at the FDA. She is currently Professor Emerita in the Department of Nutrition, University of California, Davis. We believe that Dr. Schneeman can serve effectively as a member of the committee and that the committee can produce an objective report, taking into account the composition of the committee, the work to be performed, and the procedures to be followed in completing the work.
After an extensive search, we have not identified another individual who is available to serve, with an equivalent combination of practical experience and expertise as Dr. Schneeman and who does not have a similar conflict of interest. Therefore, we have concluded that this potential conflict is unavoidable.
Waiver for Disclosed Conflict of Interest: Jamy Ard, M.D.
In accordance with Section 15 of the Federal Advisory Committee Act, the โAcademy shall make its best efforts to ensure that no individual appointed to serve on [a] committee has a conflict of interest that is relevant to the functions to be performed, unless such conflict is promptly and publicly disclosed and the Academy determines that the conflict is unavoidable.โ A conflict of interest refers to an interest, ordinarily financial, of an individual that could be directly affected by the work of the committee. As specified in the Academy's policy and procedures (http://www.nationalacademies.org/coi/index.html), an objective determination is made for each provisionally appointed committee member whether or not a conflict of interest exists given the facts of the individual's employment and the task being undertaken by the committee. A determination of a conflict of interest for an individual is not an assessment of that individual's actual behavior or character or ability to act objectively despite the conflicting interest.
We have concluded that for this committee to accomplish the tasks for which it was established, its membership must include, among others, at least one person who has extensive current experience and expertise in public health nutrition that includes management of obesity in key at-risk populations including racial/ethnic groupsโparticularly African Americansโand older adults.
To meet this expertise and experience, Dr. Jamy Ard is proposed for appointment to the committee even though we have concluded that he has a conflict of interest because in addition to his academic appointments, he serves as medical director for a medical food-based program that is owned by a company in the food industry.
As described in Dr. Ardโs biographical summary, he specializes in clinical management of obesity, especially for those in racially diverse at-risk populations living with chronic diseases. He has 20 years of experience in clinical nutrition and obesity and served as the vice-chair for clinical care in the University of Alabama at Birminghamโs Department of Nutrition Sciences. Dr. Ard has a special interest in the African American population and in developing strategies for behavior modification that are culturally appropriate for this group and has worked on several NIH-funded multicenter trials, including Dietary Approaches to Stop Hypertension (DASH), a key dietary pattern in the Dietary Guidelines for Americans; DASH-Sodium; and Weight Loss Maintenance Trial. We believe that Dr. Ard can serve effectively as a member of the committee and that the committee can produce an objective report, taking into account the composition of the committee, the work to be performed, and the procedures to be followed in completing the work.
After an extensive search, we have not identified another individual who is available to serve, with an equivalent combination of practical experience and current expertise in public health nutrition related to management of obesity in diverse population groups as Dr. Ard and who does not have a similar conflict of interest. Therefore, we have concluded that this potential conflict is unavoidable.
Waiver for Disclosed Conflict of Interest: Susan B. Roberts
In accordance with Section 15 of the Federal Advisory Committee Act, the โAcademy shall make its best efforts to ensure that no individual appointed to serve on [a] committee has a conflict of interest that is relevant to the functions to be performed, unless such conflict is promptly and publicly disclosed and the Academy determines that the conflict is unavoidable.โ A conflict of interest refers to an interest, ordinarily financial, of an individual that could be directly affected by the work of the committee.

A determination of a conflict of interest for an individual is not an assessment of that individual's actual behavior or character or ability to act objectively despite the conflicting interest.
We have concluded that for this committee to accomplish the tasks for which it was established, its membership must include, among others, at least one person who has extensive current experience and expertise in metabolic health and energy management that includes clinical research of obesity.
To meet this expertise and experience, Dr. Susan Roberts is proposed for appointment to the committee even though we have concluded that she has a conflict of interest because she serves as chief scientific advisor and shareholder of a weight management company.
As described in Dr. Robertsโ biographical summary, she specializes in weight regulation and energy metabolism. She has almost 30 years of experience in nutrition and clinical research and serves as director of the Energy Metabolism Laboratory at Tufts University. Dr. Robertsโ extensive experience in clinical research is focused on the design, conduct, and analysis of randomized trials involving determinants of weight regulation, including dietary composition factors such as glycemic index, protein and fiber, and behavioral factors in weight control. Dr. Roberts is a recognized expert in weight regulation and obesity research and her familiarity with the practical aspects of the Dietary Guidelines for Americans is critical to the committeeโs work. We believe that Dr. Roberts can serve effectively as a member of the committee and that the committee can produce an objective report, taking into account the composition of the committee, the work to be performed, and the procedures to be followed in completing the work.
After an extensive search, we have not identified another individual with an equivalent combination of current practical clinical experience and expertise in metabolic health and energy management as Dr. Roberts and who does not have a similar conflict of interest. Therefore, we have concluded that this potential conflict is unavoidable.
