High protein consumption and bone density

[Guest guest]

I've read material in different sources (Dr. Byrnes's and Weston

Price Foundation's) arguing that protein in whole foods doesn't cause

bone loss... and believed it. But now I got two peices of information

that don't fit here:

1. I am quoting from some place: " Studies now show that high levels

of protein — particularly animal protein — in the American diet drain

calcium from the body. Observations of various populations worldwide

show that societies with high protein consumption have a high

incidence of osteoporosis. Eskimos, for example, eat large amounts of

protein due to their heavy consumption of fish. Their diet is also

extemely high in calcium, yet they suffer from high rates of

osteoporosis. The amino acids released by protein in the body tend to

deplete calcium from the bones. The calcium is then excreted in the

urine. "

Is what is said above about Eskimos correct?

2. I've talked to a woman in her senior years, and she said that when

she went on a high protein/low carb diet, she lost extra weight and

her blood lipids normalized; however, her bone density decreased too.

She said that she had tested before and after starting the diet.
