Blood levels of trans–fatty acids in white adults in the U.S. population decreased by 58 percent from 2000 to 2009 according to a Centers for Disease Control and Prevention study published in the Feb. 8 edition of the Journal of the American Medical Association. This research is a part of CDC′s larger National Biomonitoring program, which currently measures more than 450 environmental chemicals and nutritional indicators in people. The current study provides information for white adults only, and additional CDC studies are under way to examine blood TFAs in other adult race/ethnic groups, children, and adolescents.
