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 intakes and bone mineral status: a cross sectional study in 5 age and sex cohorts.
BACKGROUND Evidence is increasing for positive effects of fruit and vegetable intakes on bone health . However , most of the studies to date were conducted in adults , and few reports included adolescents . OBJECTIVE We explored the association between bone mineral status and fruit and vegetable intakes in adolescent boys and girls ( aged 16 - 18 y ) , young women ( aged 23 - 37 y ) , and older men and women ( aged 60 - 83 y ) . DESIGN Bone mineral measurements of the whole body , hip , and spine were made in all subjects by using dual-energy X-ray absorptiometry . Information on health and lifestyle and physical activity was obtained by question naire . Fruit , vegetable , and nutrient intakes were ascertained from 7-d food diaries . RESULTS In adolescent boys and girls and older women , significant positive associations were observed between spine size-adjusted bone mineral content ( SA- BMC ) and fruit intake . In boys only , femoral neck SA- BMC was also significantly and positively associated with the intakes of both fruit and dietary vitamin C. No significant associations were found in the young women or older men , or between bone measurements and intake of vegetables alone ( after adjustments ) in any of the groups . CONCLUSIONS Higher fruit and vegetable intakes may have positive effects on bone mineral status in both younger and older age groups , especially at the spine and femoral neck . The specific mechanisms remain to be ascertained , but vitamin C , other fruit-specific antioxidants , and lifestyle may play a role
