Abstract
Objectives: To compare the effect of a soy rich diet and hormone replacement therapy (HRT) on
the main biomarkers of bone turnover and bone mineral density (BMD) at postmenopausal
age. Methods: 187 healthy asymptomatic postmenopausal women, aged 39–60, were recruited and randomized
into a soy rich diet group, a HRT group, and a control group. Bone biomarkers and
BMD were evaluated at baseline and after 6 months at the end of the study. Results: Diet is not as effective as HRT in reducing the postmenopausal turnover; however
diet stimulates bone osteoblastic activity, as evidenced by significant increase in
osteocalcin concentrations. BMD decreases significantly only in the control group,
but not in the intervention groups. Conclusions: Our data suggest that soy products could be effective in reducing the risk of osteoporosis
in asymptomatic postmenopausal women, but our findings should be confirmed before
recommending the diet as a valid alternative to HRT.
