i think you can not vegatable oil compare with real food.
oil got rancid very quickly and that's makes it very unhealthy.
Like fish oil supplements become very quickly toxic when exposed to sunlight and/or higher temp.
But i think pufa from eating whole foods like avocado, fish, nuts are less toxic.
Well, of course. Foods that contain less of a toxin than other foods are obviously going to be less toxic.
Corn and Soybean oil have about 60% of their fat from PUFA, and they are pure fat. So, 100g of either is going to give you roughly 60g of PUFA.
Avocado only has about 10-15% of it's fat from PUFA, and 100g of avocado only contains about 2g of PUFA. So, to get the same amount of PUFA from avocados, you'd have to eat 3 kilos of them.
Atlantic Salmon has about 35-40% of it's fat from PUFA, and to get to that same 60g of PUFA, you'd have to eat about 1.5 kilos.
I don't know anyone that eats 3 kilos (over 6 pounds) of avocados every day. 100g of soybean oil is easier to hit, if you eat a lot of processed foods and at restaurants. And eating 3 pounds of salmon is also doable, though rare. That's part of the reason why Peat pointed out the issues of people on fishing boats developing problems from eating lots of fatty fish.
I think the PUFA in fish, nuts, and avocado is just as toxic as the PUFA in vegetable oils, but there is just less of it.
