I've seen this before and it is something that appears to make sense
theoretically, just does not work like that in real humans. Those
consuming above average protein tend to have higher bone density
than those consuming less. This came up a few times on one of the
lists I am on (I think the lowcarb-l). There was an explanation of
how the body handles the acid and it wasn't by leaching calcium out
of the bones. As usual, I don't remember what it was - saw it, groked it,
and forgot it as no longer needed.
