Is There a Benefit to Cold Pressed Olive Oil?

Olive oil and avacato oil are considered very healthy oils, if you can afford them. There's a big scandal in the olive oil industry where they cut the oil. I don't want to give too much credence to any one of these studies. The worst case tonow you can get is a highly refined oil that's been heated and coiled, cooled. If you're fat adapted, do you need to add any oil at all? Right?
