It's the ammonia that bothers me. That does not belong in contact with a foodstuff.

Whey protein was used to fatten pigs in the past. I have no problem with it being used to fatten children.

But wait a minute. There are children hungry because their parents cannot afford to feed them more acceptable forms of protein, so it's OK to feed them what has been used as animal feed in the past? It strikes me there is something profoundly wrong with that logic.
