Updating the Dietary Guidelines for Americans
The Departments of Agriculture and Health and Human Services are required to publish the Dietary Guidelines for Americans every five years. By law, the Dietary Guidelines must be based on the body of scientific evidence on diet and health. Nutrition science evolves over time, and updating the Dietary Guidelines every five years allows the Departments to update the recommendations based on current research and public health concerns.
Each edition of the Dietary Guidelines builds on the edition that came before it, with the scientific justification for updates and changes informed by the Dietary Guidelines Advisory Committee’s scientific report and consideration of public and Federal agency comments. The scientific report provides the Advisory Committee’s independent review of the current state of nutrition science and includes evidence-based information for consideration as the Departments develop the next edition of the Dietary Guidelines. The Advisory Committee’s scientific review helps inform the Departments’ development of the Dietary Guidelines -- it’s a scientific report and not a draft of the Dietary Guidelines.
The process to develop the Dietary Guidelines can and has changed over time. Since the review of the science on diet and health is currently under way, it is too early to say what will be included in the 2020-2025 Dietary Guidelines for Americans.
