Dr. Joseph Lau, Professor Emeritus of Health Services, Policy, and Practice is serving as member of one of The National Academies of Sciences committees. The committee, Review of the Process to Update the Dietary Guidelines for Americans came out with a second NGA report, titled "Redesigning the Process for Establishing the Dietary Guidelines for Americans".
From the National Academies website:
The Dietary Guidelines for Americans (DGA) provides nutritional and dietary information with the intention of promoting health and preventing chronic disease, and serves as the basis for all federal nutrition policies and nutrition assistance programs, as well as nutrition education programs. This guidance is updated and released every 5 years by the U.S. Department of Agriculture (USDA) and the U.S. Department of Health and Human Services (HHS). The process of updating the DGA is informed by an assessment of relevant scientific data by a federal advisory committee of nationally recognized experts, called the Dietary Guidelines Advisory Committee (DGAC). Congress mandated that the National Academies of Sciences, Engineering, and Medicine (the National Academies) evaluate the process used to update the DGA. This mandate resulted in two reports. The first report,Optimizing the Process for Establishing the Dietary Guidelines for Americans: The Selection Process, highlighted opportunities to improve the DGAC selection process. This second report, Redesigning the Process for Establishing the Dietary Guidelines for Americans, offers a comprehensive review and recommendations for improving the rest of the process to update the DGA.
