This is important, so I am telling everyone.  Provided you have
enough fat, "protien overload" is a myth.  One day as a child I was eating
ham.  I never did like ham, except shaved as a lunch meat, so I thought I
could improve the flavor by putting salt on it.  My father said I may as
well bend over backwards and kiss my kidneys goodbye.  Studying the
history of meat, I agree with the old man that it is the salt and
excessive spices (and perhaps the spoiledge they were to prevent or mask)
that is murder on the kidneys, not the meat itself.  Provided with a low
sodium diet with spice as an occasion flavoring and not at every meal,
there is no reason (other than food alergy) that a person should not be
able to live quite well on nothing more than several pounds of beef per
day.
