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. Currently, the U.S. Departments of Health and Human Services (HHS) and Agriculture (USDA) are asking for nominations to the 2025 Dietary Guidelines Advisory Committee.

Nominees should have expertise in one or more of the scientific topics the Committee will address. You can read more about the evidence review below. To nominate yourself or a colleague to serve on the Committee, please submit your nomination by July 15, 2022, 11:59 p.m. ET.

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.

Nomination Package Review

All complete nomination packages will be reviewed by HHS and USDA program staff based on education, professional experience, and scientific expertise, with a goal towards establishing a diverse membership that is reflective of the racial, ethnic, gender, and geographic diversity within the United States. 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 will include 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 will 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 will submit a confidential financial disclosure report upon appointment and annually thereafter. Each report will be reviewed by HHS ethics officials for financial conflicts of interest and compliance with Federal ethics rules.

HHS and USDA Secretary Review and Appointment

Formal nomination recommendations of proposed Committee members will be prepared for review by the Secretaries of HHS and USDA. Individuals who are appointed to serve on the Committee will be jointly agreed upon by the Secretaries of HHS and USDA. The Committee members are appointed as Special Government Employees (SGEs) and are subjected 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.

The Committee will review evidence starting in early 2023 until late 2024. They 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 recently asked for public comments on the 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 are considering all public comments posted to as we prioritize the scientific questions to be examined by the Committee and determine if edits or changes to the scientific questions are needed. To inform the expertise needed on the Committee, HHS and USDA are providing an overview of the scientific topics and health outcomes that the Committee will be asked to address.

Scientific Expertise graphic

The Committee’s evidence review will focus on diet and health outcomes across the lifespan. This will include the relationship between diet and risk of overweight and obesity across the lifespan with a new emphasis on weight loss and weight maintenance for adults. The evidence review will also address ultra-processed foods and food-based strategies that can be used by individuals and families to support implementation of the Dietary Guidelines and help prevent or manage overweight and obesity.

The Committee will use a health equity lens across its evidence review to ensure factors such as socioeconomic status, race, ethnicity, and culture are described and considered to the greatest extent possible based on the information provided in the scientific literature and data. The Committee’s review will also consider evidence across the lifespan and will tailor its approach to address any life stage-specific considerations. Life stages to be examined include infants, toddlers, children, adolescents, adults, individuals who are pregnant or lactating, and older adults.

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.
