I have a nuanced take on nuts and fruits such as avocados that contain PUFAs.
While they contain PUFAs, they also contain vitamin E. As a whole food, I think the destructive effects of PUFA are countered by the Vitamin E in them. On the other hand, I can hardly find Vitamin E in foods that have SFAs. Granted, coconut has some tocotrienols in them, which some may consider to be a beneficial kind of vitamin E but I'm not convinced of this.
So I would take nuts and such fruits when it is season, when they are available free in the backyards or cheap and affordable. If they're not healthful, I don't take them daily or throughout the year. At worst, their effects are at worst limited as it is not built into my daily lifestyle.
What matters more to me is what I eat daily and is part of my lifestyle of eating. I has gone cold turkey on PUFA for at least 4 years, and believe by my improved health after those 4 years to validate Ray's teachings on the toxicity of PUFAs. These days, I still use SFAs as my cooking oil, but can't help to eat chicken and pork, which contain PUFAs in their days. I can minimize PUFA intake from eating them by not eating the fat portions, but can't help eat some PUFAs from them in the sauce and drippings, and as part of the meat.
I now can afford to minimization rather than a total PUFA elimination diet. I use butter, ghee, refined coconut oil, and fully hydrogenated coconut oil (especially for deep frying , though I air fry but there is no contest comparing deep to air fry).
I'm happy enough we enjoy Coke and have no guilt eating sweets. I am a social beer drinker even though the lactic acid in beer is a no no. And I like kimchi and sauerkraut, but don't eat them regularly as much as I eat well-cooked green leaves. About avocado, they're in season one month in a year, the rest of the year I eat bananas, papaya, pineapple, watermelon , honeydew, mangoes etc.
I guess what I'm saying the good stuff I eat will overpower the bad I enjoy from time to time. For me, life is to be enjoyed, and enjoying a full life matters more. Not that I see this lifestyle as being in conflict with a predominantly healthy one.
