>This is significant because pristine vegetable oils are expected to be a healthier food than animal fat, while vegetable oils that have been strongly heated are expected to be a less healthy food than strongly heated animal fat.

Not true. Omega 6 is worse than animal fat even not fried. It just isn't part of the study.
