Ray never claims that he thinks that "Peat-esque" diet is ancestrally consistent and probably for good reason. I think it would make a lot of sense for our ancestors to have eaten PUFAs as Winter approached to intentionally slow metabolic rate to gain some fat for the winter. It wouldn't make a lot of sense for our ancestors to go into the Winter when food was scarce with their metabolic rate was through the roof. Also, many foods like fish, avocados, and nuts tend to have a relatively higher amount of Vitamin E which cancels out some of the PUFAs effects. You really think our ancestors just caught some wild salmon and said, "oh, nah this thing is filled with PUFAs" and threw it back in ?.
Now I'm not saying that we should eat PUFAs as modern-day humans, but the majority of us also live within a few miles of whole foods and a year-round plentiful food supply. If we're attempting to be as optimal as possible we would likely want to avoid as many PUFAs as possible to keep our metabolic rate as high as possible and I think for this reason it's very likely that our ancestors didn't live as long as we do today.
