Proposed Scientific Questions to Inform the Development of the Dietary Guidelines for Americans, 2025-2030: Available for Public Comment April 15 to May 16!

The development process for the Dietary Guidelines for Americans, 2025-2030 is kicking off and we want you to get involved! Today the U.S. Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) released the proposed scientific questions that will inform the next edition of the Dietary Guidelines. Starting April 15, HHS and USDA will be requesting public comments on the proposed questions. This is the first of several opportunities for public input on the Dietary Guidelines development process.

We Want to Hear from You

Learn more about the proposed scientific questions
The scientific questions inform what scientific expertise is needed on the 2025 Dietary Guidelines Advisory Committee and where the committee will focus their scientific review of nutrition evidence. The proposed questions focus on diet and health outcomes across the lifespan. This includes the relationship between diet and risk of overweight and obesity. The questions feature a new emphasis on weight loss and weight maintenance because the prevalence of obesity continues to increase and is associated with other chronic diseases such as type 2 diabetes and cardiovascular disease. New questions also address ultra-processed foods and food-based strategies that can be used by individuals and families to put the Dietary Guidelines into action and help prevent or manage overweight and obesity. A health equity lens will be incorporated across all questions. Additional information about how these questions were developed is available at

How do I submit a comment?
After reviewing the proposed scientific questions and development criteria, individuals and organizations can submit comments through HHS and USDA will accept written comments on the proposed questions from April 15 to May 16, 2022. HHS and USDA will carefully consider all relevant comments in refining the scientific questions.
