WASHINGTON — The U.S. Department of Health and Human Services (H.H.S.) Secretary Kathleen Sebelius and U.S. Department of Agriculture (U.S.D.A.) Secretary Tom Vilsack on May 30 announced the appointment of 15 experts to serve on the 2015 Dietary Guidelines Advisory Committee. The committee’s recommendations and rationale will serve as a basis for the eighth edition of the Dietary Guidelines for Americans.

The Dietary Guidelines serve as the foundation for national nutrition programs, standards and education. In addition, they provide key recommendations for the general population as well as specific population groups to help people choose an overall healthy diet that works for them.

“As we aim to improve the health of all Americans, we look forward to the important work of this committee,” Ms. Sebelius said. “Their guidance will help shape recommendations on how we can all live healthier lives by eating a nutritious diet — a key factor in achieving and maintaining a healthy weight.”

Mr. Vilsack said President Barack Obama and First Lady Michelle Obama have made it a priority to ensure Americans have access to the information they need to improve overall health and nutrition.

“U.S.D.A. takes great pride in partnering with the Department of Health and Human Services as we strive to reverse childhood obesity and build a healthier next generation based on the solid science that undergirds the Dietary Guidelines for Americans,” Mr. Vilsack said.

Every five years, the Dietary Guidelines for Americans are updated and published jointly by the H.H.S. and the U.S.D.A. The administrative responsibility for leading the process alternates between departments. The Office of Disease Prevention and Health Promotion at the H.H.S. is the administrative lead for the 2015 process.

The inaugural meeting of the committee is scheduled for June 13-14 and will be open to the public. Additional information, including meeting details, press releases and fact sheets will be available at www.DietaryGuidelines.gov.
