From a paleo viewpoint, if you get grass fed (and grass finished) meat and dairy, it should be 100% healthy to eat it all. There are studies that the sat fat from grain feeding (known as the secondhand carb effect) causes problems, not animals fed as by nature they would eat.

I use unhydrogenated coconut oil for cooking and olive oil for cold uses. The coconut oil does not break down on heating like other high omega 3 oils. (olive oil breaks down when heated)
