In older people with osteoporosis , higher protein intake ( ≥ 0.8-g/kg body weight/day , i.e. , above the current RDA ) is associated with higher BMD , a slower rate of bone loss , and reduced risk of hip fracture , provided that dietary calcium intakes are adequate .
Intervention with dietary protein supplements attenuate age-related BMD decrease and reduce bone turnover marker levels , together with an increase in IGF-I and a decrease in PTH .
There is no evidence that diet-derived acid load is deleterious for bone health .
Thus , insufficient dietary protein intakes may be a more severe problem than protein excess in the elderly .
A summary of systematic review s and meta-analyses addressing the benefits and risks of dietary protein intakes  for  bone health in adults suggests that dietary protein levels even above the current RDA may be beneficial in reducing bone loss and hip fracture risk , provided calcium intakes are adequate .
Several systematic review s and meta-analyses have addressed the benefits and risks of dietary protein intakes for bone health in adults .
Adequate supplies of dietary protein are required for optimal bone growth and maintenance of healthy bone .
Variation in protein intakes within the “ normal ” range accounts for 2–4 % of BMD variance in adults .
Fruit and Vegetable Intake and Hip Fracture Incidence in Older Men and Women: The CHANCES Project.
The role of fruit and vegetable intake in relation to fracture prevention during adulthood and beyond is not adequately understood . We investigated the potential association between fruit and vegetable intake  and hip fracture incidence in a large sample of older adults from Europe and the United States . A total of 142,018 individuals ( 116,509 women ) aged ≥60 years , from five cohorts , were followed up prospect ively for 1,911,482 person-years , accumulating 5552 hip fractures .  Fruit and vegetable intake  was assessed by vali date d , cohort-specific , food-frequency question naires ( FFQ ) . Ηip fractures were ascertained through national patient registers or telephone interviews/ question naires . Adjusted hazard ratios ( HRs ) derived by Cox proportional hazards regression were estimated for each cohort and subsequently pooled using r and om effects meta- analysis . Intake of ≤1 serving/day of fruit and vegetables combined was associated with 39 % higher hip fracture risk ( pooled adjusted HR , 1.39 ; 95 % confidence interval [ CI ] , 1.20 to 1.58 ) in comparison with moderate intake ( > 3 and ≤5 servings/day ) ( pfor heterogeneity = 0.505 ) , whereas higher intakes ( > 5 servings/day ) were not associated with lower risk in comparison with the same reference . Associations were more evident among women . We concluded that a daily intake of 1 or < 1 servings of fruits and vegetables was associated with increased hip fracture risk in relation to moderate daily intakes . Older adults with such low fruit and vegetable consumption may benefit from raising their intakes to moderate amounts in order to reduce their hip fracture risk . © 2016 American Society for Bone and Mineral Research
