Some of the "bad fat" confusion, at least here in Canada, comes from the problem that most "meat" animals are fattened up using grains (wheat), so the fat content is much higher is Omega 6 (inflammatory) fats compared to the amount of "healthy" fats (Omega 3s) that are found in higher amounts in wild caught fish and grass fed beef etc. That is my main concern with the general assumption that "animal fats" are not harmful. Grass fed butter is EXTREMELY expensive here, as is grass-fed beef. Even the poulty products are fed a lot of grains. Almost impossible to get away from (sadly).
