Recent in vivo studies have shown that protein intake is indeed positively associated with bone density. One study showed that increased protein along with calcium supplements increased bone density in the elderly. In another study, it was protein intake alone, and specifically ANIMAL protein not vegetable source that improved bone densisty. Both of these studies were published this year 2002, and I've posted the reports here in our Research forum. Check out:
