Urine calcium excretion rates were consistent with osteoporosis development ; however calcium balance studies did not demonstrate loss of whole body calcium with higher net acid excretion .
No study revealed a biologic mechanism functioning at physiological pH. Finally , r and omized studies did not provide evidence for an adverse role of phosphate , milk , and grain foods in osteoporosis .
Conclusions A causal association between dietary acid load and osteoporotic bone disease is not supported by evidence and there is no evidence that an alkaline diet is protective of bone health
Background Modern diets have been suggested to increase systemic acid load and net acid excretion .
In response , alkaline diets and products are marketed to avoid or counteract this acid , help the body regulate its pH to prevent and cure disease .
The objective of this systematic review was to evaluate causal relationships between dietary acid load and osteoporosis using Hill 's criteria .
Fruit and vegetable consumption and bone mineral density: the Northern Ireland Young Hearts Project.
BACKGROUND Studies examining the relation between bone mineral density ( BMD ) and  fruit and vegetable consumption  during adolescence are rare . OBJECTIVE Our objective was to determine whether usual fruit and vegetable intakes reported by adolescents have any influence on BMD . DESIGN BMD was measured by dual-energy X-ray absorptiometry at the nondominant forearm and dominant heel in a r and om sample of 12-y-old boys ( n = 324 ) , 12-y-old girls ( n = 378 ) , 15-y-old boys ( n = 274 ) , and 15-y-old girls ( n = 369 ) .  Usual fruit and vegetable consumption  was assessed by an interviewer-administered diet history method . Relations between BMD and fruit and vegetable intake were assessed by using regression modeling . RESULTS Using multiple linear regression to adjust for the potential confounding influence of physical and lifestyle factors , we observed that 12-y-old girls consuming high amounts of fruit had significantly higher heel BMD ( beta = 0.037 ; 95 % CI : 0.017 , 0.056 ) than did the moderate fruit consumers . No other associations were observed . CONCLUSION High intakes of fruit may be important for bone health in girls . It is possible that fruit 's alkaline-forming properties mediate the body 's acid-base balance . However , intervention studies are required to confirm the findings of this observational study
