Dietary Acid

Findings of studies on the link between dietary acid-base balance and bone mass are relatively mixed. We examined the association between dietary acid-base balance and bone mineral density (BMD) in a sample of Iranian women, hypothesizing that a higher dietary acidity would be inversely associated with BMD, even when dietary calcium intake is adequate. In this cross-sectional study, lumbar spine and femoral neck BMDs of 151 postmenopausal women aged 50 - 85 years were measured using dual-energy x-ray absorptiometry. Dietary intakes were assessed using a validated food frequency questionnaire. Renal net acid excretion (RNAE), an estimate of acid-base balance, was then calculated indirectly from the diet using the formulae of Remer (based on dietary intakes of protein, phosphorus, potassium, and magnesium; RNAERemer) and Frassetto (based on dietary intakes of protein and potassium; RNAEFrassetto), and was energy adjusted by the residual method. After adjusting for potential confounders, multivariable adjusted means of the lumbar spine BMD of women in the highest tertiles of RNAERemer and RNAEFrassetto were significantly lower than those in the lowest tertiles (for RNAERemer: mean difference -0.084 g/cm2; P=0.007 and for RNAEFrassetto: mean difference - 0.088 g/cm2; P=0.004). Similar results were observed in a subgroup analysis of subjects with dietary calcium intake of >800 mg/day. In conclusion, a higher RNAE (i. e. more dietary acidity), which is associated with greater intake of acid-generating foods and lower intake of alkali-generating foods, may be involved in deteriorating the bone health of postmenopausal Iranian women, even in the context of adequate dietary calcium intake.

Calcium Loss

The original contributions of Jacob Lemann to mineral metabolism, especially calcium metabolism and idopathic hypercalciuria, are reviewed. One group of studies concern acid base balance and calcium loss, showing that acid loads increase calcium loss in the urine. Another group of studies concern the calciuria of glucose or carbohydrate ingestion, with the observation that stone patients, who as a population are enriched with hypercalciuria, respond with more exaggerated calciuria to glucose loads than do normal people. Yet another body of work shows that normal men, when given noncalcemic loads of calcitriol, exhibit two essential features of idiopathic hypercalciuria--hyperabsorptive hypercalciuria and bone mineral loss on a low-calcium diet. The final group of studies presented worked on the problem of thiazide hypocalciuric action, and where the calcium goes that does not appear in the urine, as well as the effects of potassium bicarbonate and sodium loads on mineral balance and acid base status.

Friesian Cows

The objective of this study was to determine the effect of an anionic diet on mineral metabolism, acid-base status and udder oedema of dairy cows fed grass silage based diets during the dry period. Eighteen pregnant, non-lactating Friesian cows were divided randomly into two groups according to their expected calving date. Dietary cation-anion balance (DCAB), calculated as mill equivalents [(Na + + K + ) - (Cl - + S 2- )], for high DCAB (control) and low DCAB treatments were +254 and -41 mEq kg -1 dry matter (DM), respectively. Anionic salts were ammonium chloride (NH 4 Cl), magnesium chloride (MgCl 2 ) and magnesium sulphate (MgSO 4 ). Cows received grass silage (5.2 kg DM), hay (0.9 kg DM) and a concentrate mixture (2.7 kg DM) until calving. Blood and urine samples were collected 4, 3, 2 and 1 week before the expected calving date, at calving, 1 day and 1 week after calving. Udder oedema was evaluated by a quantitative and a subjective method. Acidification resulted in a marked decrease in urinary pH, increased urinary Ca excretion and a change in blood acidbase balance. Blood Ca 2+ and plasma Ca tot concentrations were more stable at parturition for the anionic group, although such differences were not statistically significant. Anionic salts (DCAB -41 mEq kg -1 DM) did not cause udder oedema in experimental cows.;
