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 .
A diet high in meat protein and potential renal acid load increases fractional calcium absorption and urinary calcium excretion without affecting markers of bone resorption or formation in postmenopausal women.
Our objective in this study was to determine the effects of a high-protein and high-potential renal acid load ( PRAL ) diet on calcium ( Ca ) absorption and retention and markers of bone metabolism . In a r and omized crossover design , 16 postmenopausal women consumed 2 diets : 1 with low protein and low PRAL ( LPLP ; total protein : 61 g/d ; PRAL : -48 mEq/d ) and 1 with high protein and high PRAL ( HPHP ; total protein : 118 g/d ; PRAL : 33 mEq/d ) for 7 wk each separated by a 1-wk break . Ca absorption was measured by whole body scintillation counting of radio-labeled (47)Ca . Compared with the LPLP diet , the HPHP diet increased participants ' serum IGF-I concentrations ( P < 0.0001 ) , decreased serum intact PTH concentrations ( P < 0.001 ) , and increased fractional (47)Ca absorption ( mean ± pooled SD : 22.3 vs. 26.5 ± 5.4 % ; P < 0.05 ) and urinary Ca excretion ( 156 vs. 203 ± 63 mg/d ; P = 0.005 ) . The net difference between the amount of Ca absorbed and excreted in urine did not differ between 2 diet periods ( 55 vs. 28 ± 51 mg/d ) . The dietary treatments did not affect other markers of bone metabolism . In summary , a diet high in protein and PRAL  increases the fractional absorption of dietary Ca , which partially compensates for increased urinary Ca , in postmenopausal women . The increased IGF-I and decreased PTH concentrations in serum , with no change in biomarkers of bone resorption or formation , indicate a high-protein diet has no adverse effects on bone health
