I assume you’re talking about this article: http://www.westonaprice.org/know-your-fats/precious-yet-perilous
My summary of it is: there does appear to be a need for small amounts of “essential fatty acids” in humans, but you’ll easily get enough of them eating a well-balanced diet, so no need to overtly supplement or force yourself to eat foods high in them.
This doesn’t seem to be that far off from the Peat view. Funny that Mary Enig had an article basically arguing over the syntax vs. semantics of “essential” with Ray Peat. I can’t seem to find that article on the website now; I wonder if they deleted it?
As for acne, I’m a long-time sufferer. The best nutrients I can recommend based on personal experience are zinc (oysters ~3x per week) and B vitamins (brewer’s yeast). Also, making sure you blood sugar stays stable and doesn’t drop too low. Getting enough vitamin A (liver) didn’t seem to have much effect with me, but I still eat pate regularly as desired.
