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 .
Adherence to a vegetable-fruit-soy dietary pattern or the Alternative Healthy Eating Index is associated with lower hip fracture risk among Singapore Chinese.
Data on overall  dietary pattern  and osteoporotic fracture risk from population -based cohorts are limited , especially from Asian population s. This study examined the relation between overall diet and hip fracture risk by using principal components analysis ( PCA ) to identify dietary pattern specific to the study population and by using the Alternative Healthy Eating Index ( AHEI ) 2010 to assess dietary quality . The Singapore Chinese Health Study is a prospect i ve population -based cohort that enrolled 63,257 Chinese men and women ( including both pre- and postmenopausal women ) aged 45 - 74 y between 1993 and 1998 in Singapore . Habitual diet was assessed by using a vali date d food-frequency question naire . Two dietary patterns , the vegetable-fruit-soy ( VFS ) pattern and the meat-dim-sum ( MDS ) pattern , were derived by PCA . Overall dietary quality was assessed according to the AHEI 2010 , which was defined a priori for chronic disease prevention . A Cox regression model was applied with adjustment for potential confounders . In both genders , higher scores for the VFS pattern and the AHEI 2010 were associated with lower risk of hip fracture in a dose-dependent manner ( all P-trend ≤ 0.008 ) . Compared with the lowest quintile , participants in the highest quintile had a 34 % reduction in risk ( HR : 0.66 ; 95 % CI : 0.55 , 0.78 ) for the VFS pattern and a 32 % reduction in risk ( HR : 0.68 ; 95 % CI : 0.58 , 0.79 ) for the AHEI 2010 . The MDS pattern score was not associated with hip fracture risk . An Asian diet rich in plant-based foods , namely vegetables , fruit , and legumes such as soy , may reduce the risk of hip fracture
