AbstractObjectiveThe risk factors for fractures are incompletely understood. An outstanding question concerns the optimal amount of dietary calcium needed to minimise the risk of fracture.DesignWe examined the associations of dietary calcium and other nutrients with self-reported fracture risk in a prospective cohort study. Nutrient intakes were estimated using a semi-quantitative food-frequency questionnaire administered at recruitment.SettingThe UK.ParticipantsA total of 26 749 women and 7947 men aged 20–89 years.ResultsOver an average of 5.2 years of follow-up, 1555 women and 343 men reported one or more fractures, 72% of these resulting from a fall. Among women, fracture risk was higher at lower calcium intakes, with a relative risk of 1.75 (95% confidence interval (CI) 1.33–2.29) among women with a calcium intake of < 525 mg day− 1 compared with women with a calcium intake of at least 1200 mg day− 1 (test for linear trend, P < 0.001). The association of dietary calcium with fracture risk was stronger among women aged under 50 years at recruitment than among women aged 50 and above. Dietary calcium intake was not associated with fracture risk in men. Fracture risk was not related to the dietary intake of any other nutrient examined.ConclusionIn this population, women with a low dietary calcium intake had an increased risk of bone fracture, and this association was more marked among younger women than among older women.

A Prospective Study

This chapter reviews the results of an important observational study seeking to establish how, in individuals without a history of nephrolithiasis, dietary calcium intake is associated with the risk of symptomatic stone disease. The study found that the mean daily dietary calcium intake was lower in the group who formed stones compared to those who did not and that, after adjusting for covariates, high daily dietary calcium intake was strongly associated with decreased risk of stones.

Abstract Introduction 1 in 2 women and 1 in 5 men will suffer a fragility fracture. Research into calcium and vitamin D supplements has found no consistent evidence to suggest that they reduce the risk of osteoporotic fractures. There has been little research to suggest that dietary calcium is effective at reducing the risk osteoporotic fractures, but supplements have been linked to increased risk of cardiovascular disease and urinary stones. Bisphosphonates have been shown to reduce the risk of osteoporotic fractures and are usually taken in combination with calcium and vitamin D supplements given that deficiencies must be corrected prior to starting. This study set out to assess the dietary calcium intake of patients who attend the falls clinic and explore their attitudes towards dietary change, as an alternative or adjunct to a calcium and vitamin D tablet. Methods Data was collected during private interviews conducted with patients who attended the falls clinic. The Edinburgh University Centre for Genomic and Experimental research (CGEM) food frequency calculator was used to calculate dietary calcium intake. Microsoft Excel was used to collate and analyse the data. Results No association was found between dietary calcium intake, age and sex. We did find that mean dietary calcium intake was significantly less than the recommended daily amount for adults with osteoporosis, with 80% not getting their recommended daily intake (p &lt; 0.05). We identified patients who don’t receive a calcium and vitamin D supplement as an at-risk group who would benefit from advice on sources of dietary calcium and 83% of patients said that they would be interested in a leaflet on sources of dietary calcium. Conclusion This study has identified a group of patients who will hopefully benefit from a leaflet on sources of dietary calcium and as result improve their bone health.

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.

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.
