Seed oils? Wtf. Common sense will tell you people have been eating seed oils for thousands of years.
Okay then.
Tell me how they got oil from corn, soybeans, cottonseed, and rapeseed thousands of years ago?
Simple answer is that they didn't. That takes industrial processing and has only been in existence for 100 years or so.
Up until then fat was obtained from an animal or pressing something like olives.
