Difference between the Scientific Report and the Dietary Guidelines

The Dietary Guidelines Advisory Committee’s scientific report and the Dietary Guidelines for Americans are not the same thing. The scientific report is a review of the body of science on nutrition and health conducted by external scientific experts for the U.S. government. The Dietary Guidelines for Americans is a Federal document written by the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS), containing food-based guidance for use by Federal programs for their nutrition initiatives. As USDA and HHS write the Dietary Guidelines, they consider the findings from the Committee’s scientific report, along with comments from the public and Federal agencies. The table below provides more details about the differences between the Committee’s scientific report and the Dietary Guidelines for Americans.
