Calcium Cuts Death Risk

Previously, a number of studies have suggested that calcium helps to improve lipid profiles and reduce elevated blood pressure.  However, conflicting data exist regarding the risk-benefit of calcium supplementation on mortality. Lisa Langsetmo, from McGill University (Canada) , and colleagues examined data collected on 9,033 subjects enrolled in the Canadian Multicentre Osteoporosis Study (CaMOS) which had a 10-year follow-up during which 1,160 deaths occurred. The researchers found that daily calcium supplements up to 1000 mg reduced mortality among the women, and the results were inconclusive for supplemental intake exceeding that amount. Consequently, the study authors submit that: “Calcium supplements, up to 1000 mg/d, and increased dietary intake of calcium may be associated with reduced risk of mortality in women.”
