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 .
A comparison of the effects of feeding sulfur amino acids and protein on urine calcium in man.
It has been suggested that the sulfur amino acids in protein are responsible for the calciuria observed after protein ingestion . This hypothesis was tested by feeding meals containing either 15 g protein ( control ) , 45 g protein ( high protein ) , or 15 g protein plus sulfur amino acids equivalent to those in the high protein diet . Compared to the control , the high protein diet caused an increase in urinary calcium and sulfate and a decrease in the renal reabsorption of calcium . In contrast , the sulfur amino acid supplement had no effect on calcium excretion or reabsorption . Net acid excretion was unaffected by dietary treatment
