Calcium And Phosphorus

1. Rats were given diets containing different amounts of calcium, phosphorus and lead.2. Pb retention was greatly increased when the diets contained less Ca or P than the minimum estimated requirement of the rat.3. The release of Pb already incorporated into the skeleton was inhibited by diets low in Ca but was not affected by diets low in P.4. The retention of Pb given intraperitoneally was not affected by dietary Ca or P.5. It can be concluded that dietary Ca and P influence the absorption of Pb by the gut and dietary Ca influences the metabolism of Pb in the bone.6. There were changes in the distribution of Pb among the tissues due to changes of dietary Ca.7. At low body concentrations, Pb probably affected skeletal growth.

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.

The purpose of this study was to clarify the effects of dietary calcium (Ca) supplementation on bone metabolism of magnesium (Mg)-deficient rats. Male Wistar rats were randomized by weight into three groups, and fed a control diet (control group), a Mg-deficient diet (Mg- group) or a Mg-deficient diet having twice the control Ca concentrations (Mg-2Ca group) for 14 days. Trabecular bone volume was significantly lower in the Mg - and Mg-2Ca groups than in the control group. Trabecular number was also significantly lower in the Mg - and Mg-2Ca groups than in the control group. Mineralizing bone surface, mineral apposition rate (MAR), and surface referent bone formation rate (BFR/BS) were significantly lower in the Mg - and Mg-2Ca groups than in the control group. Furthermore, MAR and BFR/BS were significantly lower in the Mg-2Ca group than in the Mg - group. These results suggest that dietary Ca supplementation suppresses bone formation in Mg-deficient rats.

Milk Products

Purpose: Milk products (fluid milk, cheese, yogurt) typically provide a rich source of calcium and other nutrients, yet consumption is declining in Canada. This study examined milk product health beliefs among young adults and the association between these beliefs and dietary calcium intake. Methods: Seventy-nine participants (25 ± 4 y; 40 males) completed a milk product health belief questionnaire to determine a milk product health belief score (MPHBS) and a 3-day food record to assess dietary intake. Results: Despite generally positive views, young adults were uncertain about milk products in relation to health, weight management, and ethical concerns. Females would be more likely than males to increase milk product intake if they were confident that milk products are ethically produced. There was no significant association between MPHBS and dietary calcium intake. Energy-adjusted dietary calcium intake was positively associated with intakes of vitamin A (r = 0.3, P < 0.05), riboflavin (r = 0.5, P < 0.01), vitamin B12 (r = 0.5, P = < 0.01), vitamin D (r = 0.4, P < 0.01), phosphorus (r = 0.4, P < 0.01), zinc (r = 0.3, P < 0.01), and with milk and alternatives servings (r = 0.8, P < 0.01). Conclusion: Nutrition education efforts focused on increasing calcium-rich food consumption will help consumers to be better informed when making dietary choices.
