There could be a little overlooked portion of this being that damn near every plant cut for profit is a gmo project of Monsanto. So while humans may have been eating seed oils forever, seed oils ain't what they used to be.
I had my blood panel done during a hard keto run. I'd eat a solid cup of bacon fat daily and often more. My cholesterol numbers were incredibly low.
I haven't bought a piece of beef since 1993, my red meat consists of elk and deer exclusively.....and the numbers don't make me want to change.
Yeah, it's 2021 and most people still think that eating fat=high serum cholesterol. They never consider cutting out the flour, bread, potatoes and rice and looking at the effect on their serum lipids.
