Trans Fatty Acids and Human Health

چکیده
According to various studies, fats of animal and vegetable origins satisfy 22% to 42% of the daily energy demands of human beings (Srinivasan et al., 2006; Wagner et al., 2008; Willet, 2006). Some fats, and especially those that are hydrogenated, contain trans fatty acids (TFAs), i.e. unsaturated fatty acids with at least one double bond in a trans configuration (Craig-Schmidt, 2006). This trans-double-bond configuration results in a greater bond angle than for the cis configuration, thus producing a more extended fatty-acid carbon chain that is more similar to that of the saturated fatty acids (SFAs), rather than to that of the cisunsaturated double-bond-containing fatty acids (Fig. 1) (Moss, 2006; Oomen et al., 2001).
