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 .
Proteins, dietary acid load, and calcium and risk of postmenopausal fractures in the E3N French women prospective study.
Excess dietary proteins and " acid ash " diets have been suspected to increase the risk of osteoporosis , but experimental and epidemiological evidence is mixed . We aim ed to determine whether the association between protein intake and the overall acid-base equilibrium of the diet ( as renal net acid excretion [ RNAE ] estimate ) and fracture risk vary according to calcium intake . During an average of 8.37 + /- 1.73 yr of follow-up , 2408 women reported a fracture ( excluding high-impact trauma ) among 36,217 postmenopausal women from the E3N prospect i ve study . We used Cox regression models to study the interaction between calcium and , respectively , proteins and RNAE , from the 1993 dietary question naire for fracture risk determination , adjusting for potential confounders . There was no overall association between fracture risk and total protein or RNAE . However , in the lowest quartile of calcium ( < 400 mg/1000 kcal ) , high protein intake was associated with a significant increased fracture risk ( RR = 1.51 for highest versus lowest quartile ; 95 % CI , 1.17 - 1.94 ) . An increasing fracture risk with increasing animal protein intake was also observed ( trend , p < 0.0001 ) . A similar pattern of interaction for fracture risk was observed between RNAE and calcium . In this Western population of postmenopausal women with normal to high protein intake and fairly high calcium intake , there was no overall association between total protein or RNAE and fracture risk . However , there was some evidence that high protein-high acid ash diets were associated with an increased risk of fracture when calcium intake was low ( < 400 mg/1000 kcal )
