using the chart showing increasing pufa consumption correlated to obesity when the increased pufa consumption is in the form of deep frying with seed oils is disingenious
The increase in PUFA was driven by seed oils specifically. It's not "disingenuous," it's literarily what happened. While some of that was indeed from deep fried foods, a lot of it was in the form of things like salad dressing, mayo, and replacing things like butter and tallow with canola and soybean oil in regular cooking. And some of it was from a shift in fatty acid composition of livestock fat. Pig fat now has a higher proportion of PUFA than it did in the 1950s, so you are getting more PUFA simply by eating things like bacon or pork shoulder.
Besides, deep frying in and of itself is not unhealthy. French Fries used to made mostly with beef tallow. McDonalds used beef tallow for their fries from when they first started until 1990. And the PUFA content of that oil went up again in the early 2000s, when they stopped using partially hydrogenated oils. Deep frying really only becomes problematic when you start using oils that break down at high heats, and considering the high PUFA seed oils are unstable even at room temperature, this change took deep frying from fairly benign to very problematic..
when i see people with really good skin and physiques and overall aura supporting whole food pufa consumption and i see weirdos with bad physiognomies with anime
What do you mean by "whole food PUFA consumption?" This is a pretty silly statement, because you will be talking about people who eat about 30 grams less PUFA than the average person. As Ray Peat mentioned, PUFA is unavoidable, outside of a lab created diet. Even 8 ounces of Orange Juice has roughly 100mg of PUFA, and the more saturated fats like dairy fat, beef and coconut have about 2-3% of their fat as PUFA. Those who only consume PUFA in "whole foods" are going to be eating at levels closer to those in the early 1900s on the chart, unless they specifically eat nothing but salmon, flax seed, and nuts.
It's true that the vast majority of processed foods today are unhealthy, but that's only because they specifically use toxic ingredients, like high PUFA seed oils, and added iron (aka, ferrous sulfate). If these same foods where made with better ingredients, like beef tallow and coconut oil, they would be more benign, even healthy, and could easily be 20% or less of a healthy diet, that was based around meat, dairy, fruits and such.
By the way, how did you ensure these people only consumed PUFA from whole foods? Did you lock them down in a metabolic ward for a few months? Did you review their cronometer data for the past 5 years? Or, did you just hazard a guess about what they eat?
