Why do you think polyunsaturated fats are bad for you? What does it do to you mechanistically? And where did you learn this from? Also isn’t it a bit hyperbolic to call it poison? It doesn’t literally kill you. I’m sure you would choose to drink a glass of seed oil before you had a teaspoon of cyanide.

Idk dude, your beef fat contains 4% “poison.” And palm kernel oil, a seed oil, has less “poison” than beef fat 😂

I hear you, doctors emphasize the PUFA for why seed oils are bad and I don't see them giving enough credence to the way they are made, which I find to be an even worse evil. I can find dozens of research papers on how seed oils are made to be edible and they are completely about turning something that is not food into something that the human body will not reject, either metabolically or physically, like revulsion from bad taste, smell, color. Zero regard for health, if the Food and Drug Administration was not fully captured and corrupt, those oils would be illegal.

PUFA are fragile oils that become toxic as they break down. In the production of seed oils, they are absolutely shredded. Not to mention the extreme imbalance caused by consuming unnaturally high amounts that would be impossible to achieve without heavy industrial processing.
