Yes -- that too! :^)
What really fries me are all these morons who argue about grain-fed beef and dairy critters, saying "We could use that same grain to feed millions more people!" NO, they coudln't use that same grain to feed people! If people tried to eat the same grain fed to livestock, which is grown on acreage not of the right soil or in the right climate/rainfall to profitably grow human-consumable crops, they'd die of malnutrition because they don't have four stomachs to process it! When I explained this to a vegan acquaintance, I remember the blank look on her face and then the light bulb went on ... DUH!!!! Even she saw that I spoke the truth; she shut up with that particular argument after that.
You can’t feed corn/soybeans etc. to people ?
I suppose if you were to strictly follow FDA guidelines for US distribution that may be true for some grains, but it certainly isn’t true in the third world, where human and animal feed grains are completely interchangable. Whole corn is whole corn to a Mexican peasant. You can feed it to your kids or you can feed it to your chickens.
Other items like some protein meals, cellulose like in hulls, etc. are not human edible. But this stuff is a minority of feed bulk.
