In the present meta- analysis , reductions in the risk of hip fracture  with milk consumption were only observed among American adults , but not among Sc and inavian adults , possibly because milk products are more commonly fortified with vitamin D in the former population than in Sc and inavian countries .
The reduction in the risk of hip fracture was also observed with yogurt consumption , which is often associated with healthy lifestyles and dietary patterns that contribute to improved bone health .
Fueling this uncertainty , the elevated  risk of hip fracture  in association with  milk consumption was observed in a cohort of Swedish women .
The cumulative evidence from prospect i ve cohort studies reassuringly suggests that the risk of hip fracture may not be elevated among people who consume milk , yogurt , and cheese , and that a greater consumption of milk or yogurt may even be associated with a lower risk of hip fracture depending on the factors that may differ across the population of interest
Although dairy products contain bone-beneficial nutrients , the association between dairy consumption and the risk of hip fracture remains equivocal .
The impact of dietary protein on calcium absorption and kinetic measures of bone turnover in women.
Although high-protein diets induce hypercalciuria in humans , the source of the additional urinary calcium remains unclear . One hypothesis is that the high endogenous acid load of a high-protein diet is partially buffered by bone , leading to increased skeletal resorption and hypercalciuria . We used dual stable calcium isotopes to quantify the effect of a high-protein diet on calcium kinetics in women . The study consisted of 2 wk of a lead-in , well-balanced diet followed by 10 d of an experimental diet containing either moderate ( 1.0 g/kg ) or high ( 2.1 g/kg ) protein .  Thirteen healthy women received both levels of protein in r and om order . Intestinal calcium absorption increased during the high-protein diet in comparison with the moderate ( 26.2 + /- 1.9 % vs. 18.5 + /- 1.6 % , P < 0.0001 , mean + /- sem ) as did urinary calcium ( 5.23 + /- 0.37 vs. 3.57 + /- 0.35 mmol/d , P < 0.0001 , mean + /- sem ) . The high-protein diet caused a significant reduction in the fraction of urinary calcium of bone origin and a nonsignificant trend toward a reduction in the rate of bone turnover . There were no protein-induced effects on net bone balance . These data directly demonstrate that , at least in the short term , high-protein diets are not detrimental to bone
