The Dietary Guidelines for Americans, 2020–2025 was issued jointly by the US Departments of Agriculture and of Health and Human Services in December 2020. It is the ninth edition of the Dietary Guidelines and is the first to provide recommendations by life stage, from birth to older adulthood. The Dietary Guidelines is grounded in the current body of scientific evidence on diet and health outcomes and aims to promote health and prevent chronic diseases. The process to develop the Dietary Guidelines involved 4 steps: (1) identifying the topics and supporting scientific questions, (2) appointing a Dietary Guidelines Advisory Committee (Committee) to review current scientific evidence, (3) developing the new edition of the Dietary Guidelines, and (4) implementing the Dietary Guidelines. The 2020-2025 edition provides 4 overarching guidelines and supporting key recommendations that encourage healthy dietary patterns across the life span. The foods and beverages that people consume have a profound impact on health, and it is never too late or too early to eat healthfully.
