I don't think he is being fair to the actual ratio of 6 to 3 that we need (2:1). Those foods that he considers "high" in Omega 6 like bacon, duck, chicken fats also have some omega 3. I would never deprive myself of bacon, duck, or chicken fat because it's supposedly high in O 6. So frying the salmon in lard or duck fat isn't going to kill you.

Edit: I'd like to see a list with the ratios of 6 to 3. Most of the stuff I see in the USDA database is mg per 100 grams, not a percentage. It'd be great if we had a list of the ratios!
