To the Editor: Dr Vesper and colleagues1 found that levels of plasma trans-fatty acids (TFAs) in a nationally representative sample of white adults studied in 2009 were lower than in a sample studied in 2000, which may be related to the US Food and Drug Administration's requirements for TFA labeling in 2003. Some data in the study and their possible implications warrant further discussion.
