You feed mammals grains and processed grains if you want to fatten them up as fast as possible for the slaughter while they're in the feedlot, if you don't care how long they live, cause a couple years is long enough. Or according to TV commercials you feed grains to little mammals of your species because you love them and they're cute. Even though it'll fatten them up and kill em. You can try and deny what biological commonalities exist for whatever reasons, but the weight scale knows better. Feeding people the same stuff that farmers use to fatten their herds will inevitably make people look like people of walmart website. No avoiding it.
