Dude, that stuff ain't food. That stuff is what they feed food to get it all fat, tender, and juicy before they slaughter it. Or to get critters make better quality eggs and dairy products.
Of course, when I was eating "the world's staples", I got nice and fat, tender, and juicy myself. Never did produce good eggs though.
LOL.
I like what a friend said: "Salad is what food eats!"
