EAT PROTEIN AND PLANTS FOR STRONG BONES
Gabe Mirkin, M.D.
Eating a enough protein and lots of foods from plants helps to keep
bones strong, according to reports in the American Journal of
If they live long enough, all women and most men will develop
osteoporosis. Studies done many years ago suggested that eating a
lot of protein increases calcium loss in the urine and therefore it
was thought that eating protein weakens bones by taking calcium out
of them. However, recent studies show that eating a lot of protein
increases calcium absorption so the extra calcium in the urine comes
from increased absorption, not from being take out of bones.
The second study showed that phytoestrogens found in soybeans,
genistein and daidzein, help to keep bones strong. Therefore, most
scientist now feel that a low-protein diet causes osteoporosis,
while a high-protein diet may prevent it; and that eating lots of
beans, seeds and nuts may help to keep bones strong.
