Calcium supplements linked to longer lifespans in women – Study finds calcium-rich diet, supplements provide equal benefits
Chevy Chase, Maryland — Taking a calcium supplement of up to 1,000 mg per day can help women live longer, according to a recent study accepted for publication in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. (A note from the blog author Nutrition Breakthroughs: “endocrinology” refers to the actions of hormones in the body. Interestingly, in this study, the benefits of longer lifespans were seen when the calcium came from any source, including dairy foods, non-dairy foods or supplements. See a list of calcium-rich foods below).
Calcium, an essential nutrient for bone health, is commonly found in dairy products as well as vitamins. Although calcium is an essential nutrient for bone health, past studies have linked calcium supplements to heart disease risk. Researchers analyzing data from the large-scale Canadian Multicentre Osteoporosis Study sought to clarify this issue and found moderate doses of calcium supplements had a beneficial effect in women.
“Our study found daily use of calcium supplements was associated with a lower risk of death among women,” said the study’s lead author, David Goltzman, MD, of McGill University in Montreal, Canada. “The benefit was seen for women who took doses of up to 1,000 mg per day, regardless of whether the supplement contained vitamin D.”
The study monitored the health of 9,033 Canadians (over a 12-year period), between 1995 and 2007. During that period, 1,160 participants died. Although the data showed women who took calcium supplements had a lower mortality (death) risk, there was no statistical benefit for men. The study found no conclusive evidence that vitamin D had an impact on mortality.
“Higher amounts of calcium were potentially linked to longer lifespans in women, regardless of the source of the calcium,” Dr. Goltzman said. “That is, the same benefits were seen when the calcium came from dairy foods, non-dairy foods or supplements.”
From the blog author Nutrition Breakthroughs: Some of the best food sources of calcium include kale, collard greens, yogurt, cheese, sardines with bones, canned salmon with bones, broccoli, okra, almonds, figs, navy beans, sweet potatoes and spinach.
