TFAs are unsaturated fatty acids that contain one or more iso- lated (i.e., non-conjugated) double bonds in a trans configuration (FDA, 2003) and the main isomer in ruminant fats is vaccenic acid (C-18:1 t11). Elaidic acid isomers (C-18:1 t9 and C-18:1 t10) are predominant in commercial hydrogenated fats/oils (Craig- Schmidt, 2006). Sources of TFAs include commercial baked foods, snack foods, fried foods, and margarines (Kandhro et al., 2008; Karabulut & Turan, 2006). The health risks of TFA have been
