WASHINGTON — Lee Sanders, senior vice-president of government relations and public affairs for the American Bakers Association, this week led members of the Grain Chain in conducting meetings with  agency representatives and members of Congress influential to the completion of the 2015 Dietary Guidelines. The group held discussions with officials from the U.S. Department of Health and Human Services and the U.S. Department of Agriculture on the importance of whole and enriched grains in the American diet, as well as concerns over the Dietary Guidelines Advisory Committees (DGAC) discussions on gluten and the expanded scope that includes sustainability. Additionally, the group discussed the importance of using sound science as a basis for the D.G.A.C.’s recommendations. The A.B.A. also discussed the need for additional implementation flexibility for whole grain buns and rolls in the school meal program.
