Good question -- I was wondering the same thing.  Also, perhaps if one is
eating sufficient fat with the protein, protein toxicity does not occur.  I
know that for much of my adult life I've regularly eaten what according to
these recent posts would be considered "toxic amounts" of protein, yet I've
never experienced any untoward symptoms ie nausea, diarrhea, malaise.
