soy phytoestrogens and bone mass

[Wuzzy]

Soy phytoestrogens have been linked to lower risk of
osteoporisis and higher bone mineral density.

Isn't it possible that it is actually the high calcium content
of soy products (tofu) and not the phytoestrogens that are
causing this? If anything, the phytoestrogens are
anti-estrogenic..

similarly i would think milk, not milk estrogen nor milk igf-1
is the main cause of increased bone mineral density in dairy
drinkers.. thanks, wuz..

Curiously, according to "effects of calcium depletion and
repletion on serum insulin-like growth factor"=1998 225-232),
Calcium induces insulin like growth factor so the JADA article
and epidemilogy that has correlated dairy (including non-fat
dairy like skim milk) with IGF-1 may be mediated by Phosphate
and Calcium levels...
