Well, there's a bit more variety there than cooking oil - I think the "healthy fat" category usually includes nuts, avocados, olive oil, salmon, etc. I don't think chicken (including the skin) is supposed to be bad either. [1] From my understanding of the available evidence, these fats are supposed to be more healthy than other animal fats / butter (saturated fat). [2] Whether saturated fats are bad or not depends on what you compare them to - they seem less healthy than say, olive oil, but might win out over refined carbs. And the most clearly bad one is trans fat which has the strongest evidence against it.
