Step 2 of 5 graphic


The Dietary Guidelines for Americans, 2025-2030 (Dietary Guidelines) development process is under way. Updating the Dietary Guidelines is a multi-year, multi-step process. The U.S. Departments of Health and Human Services (HHS) and Agriculture (USDA) began the development process earlier this year with a public comment period on the proposed topics and questions that will inform the next edition of the Dietary Guidelines. The Departments are now in the process of appointing the Dietary Guidelines Advisory Committee (Committee). HHS and USDA accepted nominations to the 2025 Dietary Guidelines Advisory Committee from June 15, 2022 to July 15, 2022.

More information is provided below about the Committee, including how it will be established and how it will conduct its scientific review to inform the next edition of the Dietary Guidelines.

Establishing the Committee

Formed Under the Federal Advisory Committee Act

The 2025 Dietary Guidelines Advisory Committee will be formed under and governed by the Federal Advisory Committee Act (FACA), which provides legal requirements for the formation and use of Federal advisory committees. The Committee will be established to provide independent, science-based advice and recommendations to be considered by HHS and USDA, along with Federal agency input and public comments, as the Departments develop the Dietary Guidelines for Americans, 2025-2030.

Committee Selection

HHS and USDA consider the following factors in reviewing nominations:

Call for Nominations Critera graphic long
  • Professional Experience At least 10 years of experience as an academic, researcher, practitioner, or other health professional in a field related to one or more of the scientific topic areas to be examined; consideration of leadership experience and participation on previous expert committees or panels.
  • Educational Background – Advanced degree in nutrition or health-related field, including registered dietitians, nutrition scientists, physicians, and those with public health degrees.
  • Demonstrated Scientific Expertise – Expertise related to one or more of the scientific topic areas to be examined by the Advisory Committee as demonstrated by number and quality of peer-reviewed publications and presentations. Expertise related to health equity and the scientific approaches used to review the evidence (systematic reviews with or without meta-analysis, food pattern modeling, and data analysis) is also desired.
  • Balanced and Diverse Membership – An Advisory Committee that is fairly balanced in terms of points of view and expertise, experience, education, and institutional affiliation, with a goal towards establishing a diverse membership that is reflective of the racial, ethnic, gender, and geographic diversity within the United States.

Nomination Package Review

All complete nomination packages are reviewed by HHS and USDA program staff based on the factors listed above. Following review by program staff, nominees will be evaluated by the HHS Assistant Secretary for Health, in consultation with the USDA Deputy Under Secretary of Food, Nutrition, and Consumer Services. 

Additional Review, Including Conflicts of Interest

The vetting process for potential members includes a background check by HHS to determine if any of the candidates have a financial, ethical, legal, and/or criminal conflict of interest that would prohibit them from serving on the Committee. In addition, HHS ethics officials ensure interests and affiliations of proposed Committee members comply with applicable conflict of interest statutes, regulations issued by the U.S. Office of Government Ethics (OGE), supplemental agency requirements, and other applicable Federal ethics rules. Each Committee member submits a confidential financial disclosure report upon appointment and annually thereafter. Each report is reviewed by HHS ethics officials for financial conflicts of interest and compliance with Federal ethics rules. 

HHS and USDA Secretary Review and Appointment

The Secretaries of HHS and USDA review formal nomination recommendations of proposed Committee members and jointly agree on individuals who are appointed to serve on the Committee. Committee members are appointed as Special Government Employees (SGEs) and are subject to applicable Federal ethics rules. Each Committee member will receive ethics training upon appointment and on an annual basis throughout their service on the Committee. Committee members are not paid for their service, although travel expenses are reimbursed.

The Committee’s Work

What the Committee Does

Committee members collaborate during committee and subcommittee meetings to develop evidence review protocols, review and synthesize evidence, present scientific findings, consider public comments, and develop a scientific report that includes independent, science-based advice and recommendations for HHS and USDA. The Committee reviews evidence starting in early 2023 until late 2024. It will meet approximately five times and all Committee meetings will be open to the public. The activities of the Committee will terminate upon delivery of its scientific report to the Secretaries or when its two-year charter expires (whichever comes first).

The Committee’s Evidence Review

HHS and USDA asked for public comments on proposed scientific questions to be examined in the review of evidence supporting the development of the Dietary Guidelines for Americans, 2025-2030. This was the first of several opportunities for public input on the Dietary Guidelines for Americans, 2025-2030 development process.

The public comment period was open from April 15 – May 16, 2022. Public comments are available on our page through (Docket ID HHS-OASH-2022-0005). HHS and USDA consider all public comments posted to in prioritizing the scientific questions to be examined by the Committee and determining if edits or changes to the scientific questions are needed. To inform the expertise needed on the Committee, HHS and USDA provided an overview of the scientific topics and health outcomes that the Committee will be asked to address.

Additional topics will also be addressed in the Dietary Guidelines for Americans, 2025-2030 using evidence-based Federal guidance available throughout the Federal government.

Scientific Approaches

The Committee will use 3 approaches to examine the evidence: Nutrition Evidence Systematic Review (NESR) systematic reviews, food pattern modeling, and data analysis. Each of these approaches has its own rigorous, protocol-driven methodology, and plays a unique, complementary role in examining the science. For each approach, staff from HHS and USDA will support the Committee's review of the evidence.

Papers Icon
NESR systematic reviews: A gold-standard evidence synthesis project that answers a nutrition question of public health importance using systematic, transparent, rigorous, and protocol-driven methods to search for, evaluate, synthesize, and grade the strength of the eligible body of evidence.
Graph Icon
Data analysis: A collection of analyses that uses national data sets to describe the current health and dietary intakes of Americans. These data help make the Dietary Guidelines practical, relevant, and achievable.
Computer Icon
Food pattern modeling: Analyses that illustrates how changes to the amounts or types of foods and beverages in a dietary pattern might affect meeting nutrient needs across the U.S. population.
