It is not possible that all fats are bad for you, since the body needs fats and makes them. Some fats are bad for you, namely the trans fats cooked up by the frankenfoods industry. All we need to do, in my opinion, is avoid those and avoid overeating. (Obviously, fats, like any foods, cause trouble during calorie overload.)
I have spent much time reading research on fats, and it seems all types of fats get praised or criticised in various places. I have not been able to find an unequivocally safe fat, and so I eat a mix of fats, to be on the safe side. I vary my cooking oils between butter, coconut oil, and good olive and macadamia oils. I cook with them lightly. The reason I vary my oils is because you do not want to rely on one sainted oil only to find out in ten years time that it was, after all, the worst of the bunch. I eat nuts, despite the supposed dangers of the polyunsaturated fats in them, because the research repeatedly identifies nuts with good health outcomes.
As I say, the problem comes with eating
too much fat overall, in which case it will flood the system and cause insulin resistance and ectopic deposition.
