“…However, a higher dietary calcium intake has been identified by some researchers as a protective factor for overweight [6,7,42-44]. The consumption of phosphorus, in addition to being associated with lower calcium absorption [5,45,46], was positively associated with global obesity and central obesity based on WC in the study by Beydoun et al [8].…”

BackgroundLow calcium:phosphorus ratios (Ca:P ratio) in habitual diet have been observed worldwide, and it has been shown to be harmful to the bone health of the population. However, no study associating this ratio with obesity was found. Thus, considering that the intake of calcium and phosphorus will generate a ratio between them, which may be associated with obesity, this research seeks at evaluating the relation between obesity and the Ca:P ratio in the habitual diet of adults.MethodsCross-sectional population-based epidemiological study with stratified and systematic sampling. The sample was composed of 506 adults, aged between 18 and 60 years, of both genders. Information on socioeconomic and demographic conditions was obtained through questionnaires completed during home visits, where anthropometric and dietary evaluations were also conducted.ResultsIn the habitual diet consumed by the study subjects, a Ca:P ratio above the median of 0.57 reduced the risk of central obesity based on waist-to-height ratio (WHtR) (OR: 0.61; 95% CI: 0.41 – 0.92). Habitual dietary intake of calcium (OR: 0.65; 95% CI: 0.43 – 0.97) and dairy products (OR: 0.56; 95% CI: 0.37 – 0.84) above the median value (485.4 mg and 0.9 servings, respectively) was found to be a protective factor related to central obesity based on WHtR.ConclusionsValues above the median for the Ca:P ratio found in the habitual diet were negatively associated with central obesity based on WHtR. In addition, calcium and dairy consumption were negatively associated with central obesity based on WHtR. Therefore, higher Ca:P ratios contributed to a lower prevalence of central obesity.

“…Two trials with 61 participants have assessed the effect of diets with sodium 20 and calcium 23 replacement on arterial blood pressure. The combined effect of both studies was protective for systolic blood pressure (-4.82; 95% CI: -11.36 to 1.73; I 2 = 0.0%, p = 0.760), although not significant.…”

BackgroundHigh blood pressure is the major risk factor for cardiovascular disease. Low blood pressure control rates in Latin American populations emphasize the need for gathering evidence on effective therapies. ObjectiveTo evaluate the effects of dietary interventions on blood pressure in Latin American populations. MethodsSystematic review. Electronic databases (MEDLINE/PubMed, Embase, Cochrane Library, CINAHL, Web of Science, Scopus, SciELO, LILACS and VHL) were searched and manual search for studies published up to April 2013 was performed. Parallel studies about dietary interventions in Latin American adult populations assessing arterial blood pressure (mm Hg) before and after intervention were included. ResultsOf the 405 studies identified, 10 randomized controlled trials were included and divided into 3 subgroups according to the proposed dietary intervention. There was a non-significant reduction in systolic blood pressure in the subgroups of mineral replacement (-4.82; 95% CI: -11.36 to 1.73) and complex pattern diets (-3.17; 95% CI: -7.62 to 1.28). Regarding diastolic blood pressure, except for the hyperproteic diet subgroup, all subgroups showed a significant reduction in blood pressure: -4.66 mmHg (95% CI: -9.21 to -0.12) and -4.55 mmHg (95% CI: -7.04 to -2.06) for mineral replacement and complex pattern diets, respectively. ConclusionAvailable evidence on the effects of dietary changes on blood pressure in Latin American populations indicates a homogeneous effect of those interventions, although not significant for systolic blood pressure. Samples were small and the quality of the studies was generally low. Larger studies are required to build robust evidence.

“…4 Some studies have shown that calcium supplementation enhanced weight loss and reduced serum lipid profile in obese subjects. 5,6 On the contrary, significant effect of calcium supplementation on serum lipid or body composition was not seen in healthy older men 7 and normal older postmenopausal women. 8 Some randomized controlled studies demonstrated that calcium supplementation has the ability to lower serum cholesterol level in hypercholesterolemic subjects [9][10][11] and hyperlipidemic patients.…”

“…2,3 Lately, a growing body of evidence suggests that calcium supplements also have beneficial effects on insulin sensitivity, blood pressure, body weight and serum lipids. [4][5][6][7][8][9][10][11][12] In a study by Jacqmain, low daily calcium intake is associated with greater adiposity in women and lipoprotein concentration in both sexes. 4 Some studies have shown that calcium supplementation enhanced weight loss and reduced serum lipid profile in obese subjects.…”

Objective. To assess the effect of oral calcium supplementation on lipid profile and atherogenic index of plasma (AIP).Methodology. This study was undertaken in 28 centrally obese male subjects [age 26.4 (6.5) years], BMI 31.6 (4.7) kg/m 2 , WC 99.4 (6.4) cm. All participants received six tablets of CaCO 3 (250 mg of elemental calcium/ capsule, for a total of 1500 md/day) for 8 weeks. Serum lipid profile including triglyceride, total cholesterol, HDL-C, LDL-C was measured at baseline and after intervention. AIP was calculated by using formula = log (TG/HDL-C). Conclusion. Eight-week calcium supplementation at 1500 mg/day led to a significant change in lipid levels and AIP.
