You don’t eat the output of most US farms either unless you subsist on field corn, soybeans, and hay.

Ooo, this is exciting, I so rarely get to be the random dumbass crawling out of the woodwork to provide a statistically-unlikely counterexample to an otherwise sound point!

I've been really enjoying eating soybeans. Absurdly good source of protein (yes, even for a bean), dirt cheap, decent source of fiber and a bunch of minerals, and pretty easy to just drop in a pressure cooker and eat however you like once it comes out.

Can't say I eat a lot of field corn or hay though.
