There appears to be little benefit of increasing protein intake for bone health in healthy adults but there is also clearly no indication of any detrimental effect , at least within the protein intakes of the population s studied ( around 0.8–1.3 g/Kg/day ) .

Effects of soy protein isolate on bone mineral density and physical performance indices in postmenopausal women-a 2-year randomized, double-blind, placebo-controlled trial
Objective : Postmenopausal decreases in body composition , physical performance , and bone mass have been shown to be reversed by estrogen , but given the concerns regarding its use , women are looking for alternatives such as soy isoflavones . Most studies on the effects of soy on bone mineral density ( BMD ) in postmenopausal women have been short-term , that is , 3 to 6 months , and failed to provide conclusive evidence . There is no evidence of its effects on physical performance . The aim of the present study was to investigate the effects of soy plus isoflavones on BMD and physical performance in postmenopausal women . Methods : This was a 2-year r and omized controlled trial . A total of 203 healthy postmenopausal women were given either 25 g of soy protein without isoflavones , 25 g of soy protein with 90 mg of isoflavones , or 25 g of milk protein ( casein and whey ) as a control agent for 24 months . Women were followed every 6 months with BMD and physical performance measurements for 2 years . Primary analysis was intent-to-treat analysis . Analysis of variance , & khgr;2 and Fisher 's exact tests , and analysis of covariance were used . Results : There was a significant decrease in the BMD of the lumbar spine and femoral neck in those who completed the study in all groups . Soy isoflavones prevented major bone loss from baseline at the femoral trochanter with no between-group significance . Physical performance measurements decreased in all the groups . Conclusions : Twenty-five grams of soy protein with 90 mg of isoflavones has no added benefit in preventing bone loss or improving physical performance
