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 ) .

Does dietary protein reduce hip fracture risk in elders? The Framingham osteoporosis study
Summary Association between dietary protein and fracture risk is unclear . We examined association between energy-adjusted protein intake  and  hip fracture risk in elders . The risk of hip fracture was reduced in upper quartiles of protein intake when compared with lowest quartile . Introduction Studies of the association between dietary protein intake and hip fracture risk are conflicting . Therefore , we examined protein intake and hip fracture risk in a population -based group of elderly men and women . Methods Five hundred seventy-six women and 370 men from the Framingham Osteoporosis Study with no previous history of hip fracture completed Food Frequency Question naires .  Energy-adjusted protein intake  was evaluated as a continuous variable and as quartiles . Incidence rates and hazard ratios were calculated , adjusting for age , BMI , sex , and energy intake . Results Among 946 participants ( mean age 75 years ) , mean protein intake  was found to be 68 gm/d . Increased protein intake was associated with a decreased risk of hip fracture compared to those in the lowest quartile of protein intake ( Q2 HR = 0.70 , Q3 HR = 0.56 , and Q4 HR = 0.63 ; all p values ≥ 0.044 ) , p for trend was 0.07 . When a threshold effect was considered ( Q2–4 vs Q1 ) , intakes in the higher quartiles combined were associated with a significantly lower risk for hip fracture ( HR = 0.63 ; p = 0.04 ) . Conclusion Our results are consistent with reduced risk of hip fracture with higher dietary protein intake . Larger prospect i ve studies are needed to confirm and extend this finding in elderly men and women
