The trans fats in animal products are mostly conjugated linoleic acids, which are actually good for you as far as we have been able to tell: https://en.wikipedia.org/wiki/Conjugated_linoleic_acid https://en.wikipedia.org/wiki/Conjugated_linoleic_acid In other words, the trans fats that result from heating a vegetable oil are almost certain bad for you -- probably really bad -- whereas the trans fats in meat we don't know a lot about, but what we do know suggests that they are good for you. (Conjugated linoleic acids are sold as nutritional supplements.)
