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 .
Calcium supplements and milk: effects on acid-base balance and on retention of calcium, magnesium, and phosphorus.
The effect of supplementing a basal diet containing 697 mg calcium daily ( 17.4 mmol/d ) with an additional 900 mg Ca daily from milk , Ca chloride , or a Ca carbonate preparation was examined in eight adult males during a 56-d metabolic balance study . The ingestion of the milk or Ca supplements had no overall effect on Ca retention by these subjects because the milk and supplements depressed apparent absorption of Ca in the gut and fractional tubular reabsorption of Ca in the kidneys . Supplementation of the diet with CaCl and to a lesser extent with milk significantly increased renal acid excretion whereas supplementation with CaCO3 depressed renal acid excretion . The three Ca supplements significantly altered magnesium and phosphorus absorption and urinary excretion in different manners but had no overall effect on retention of P or Mg . The responses of our subjects to these treatments may be different than those of subjects who are chronically in negative balance in regard to Ca
