I’d have to go with the cultivation of grain as one primary origin. I told my kids 30 years ago that if man made it (and its probably in a package) or messed with an animals natural food supply, don’t eat it or eat very little of it.
i.e., chickens are not vegetarians. Cows do not naturally eat corn - and when you feed it to them their natural omega 3 to 6 ratios go upside down. We eat their flesh and fat overloaded with O’6 for 50 years and then wonder why we have heart disease.
