*** Agreed. In fact, I find the idea that metabolic acidosis could be caused
by excess intake of meat, unless we're talking about very lean meat, by
itself. I'm no expert on human physiology, but carnivorous species that
survive solely on animal products maintain a slightly acidic urinary pH
between 6 and 7. It seems to me that if they had to utilize bone stores of
calcium to buffer urine pH, we wouldn't have any carnivore species left by
now. Granted, they are also eating some bone along with meat, fat,
connective tissues, and organs, but bone constitutes a fairly small
percentage of dietary intake except in those species adapted to eat a large
amount of bone, such as hyenas. I don't know how much bone (or other
high-calcium foods), if any, traditional Inuit eat, but I believe many Pac
NW Indian nations ate some bone (in the form of fermented fish, among other
things), as well as plant foods in season as well as stored.
