Study Finds No Link Between Calcium and Heart Disease
Recent studies have purported that too much calcium supplementation can increase the risk of heart disease and heart attack. Researchers concerned with the design of those studies conducted their own analysis and found that calcium supplements do not increase the risk of heart disease in postmenopausal women.
The researchers of this analysis examined studies gleaned from the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE databases. All of the studies took place between 1966 and 2013. A total of 661 studies considered but only 18 studies with a total of 63,563 patients ultimately met the researcher’s criteria.
After examining the data, the researchers found that there were 3,390 coronary heart disease events and 5,157 deaths. The researchers calculated the relative risk of taking calcium supplements and found that there was no support to the theory that calcium - with or without vitamin D supplementation - increases the risk of coronary heart disease or all-cause mortality.
Researchers from the Sir Charles Gairdner Hospital in Perth, Australia conducted the study. It was published on July 10, 2014, in the Journal of Bone and Mineral Research.
Calcium is best known for its effect on bone health, but previous studies suggest it can also help with weight loss, skin health, and reducing the risk of colorectal cancer and stroke. Some studies have even suggested that calcium intake is associated with increased longevity.
Calcium absorption decreases as we age, so it is especially important to make sure you are getting enough. Try adding more dairy products or start taking a high quality supplement if you’re trying to increase your calcium intake.
