Facts You Should Know About Calcium – Part 2
In the first article on the topic of calcium, its health benefits were discussed. While it is common knowledge that calcium is essential to a healthy body, we need to explore the not so widely known facts about calcium. In this second article, we will look at the studies that say calcium consumption can be harmful to our health.
The Potential Danger of Calcium Intake
Excess Calcium May Not be Good for the Heart
According a study that the British Medical Journal published in 2013, a high dose of calcium doubled the death risk due to heart disease among women. The death records of about 61,000 women, which the researchers from Sweden’s Uppsala University studied, showed that calcium intake of over 1,400 mg per day could more likely cause death. Much worse is taking calcium supplements on top of a high calcium diet because it doubled the risk of death.
Another study published by JAMA Internal Medicine in 2013 also had the same report among men. Swedish researchers from Karolinska Institute in Stockholm found that high calcium intake increased cardiovascular death risk in men by 20 percent.
Taking Calcium Could Worsen Prostate Cancer
When prostate cancer patients undergo hormone therapy, doctors tell the patients to take calcium supplements to avoid bone loss. However, recent studies say that doing so can actually be harmful.
During a hormone-depletion therapy, prostate cancer patients can lose bone mass and suffer from osteoporosis. So, doctors prescribe the intake of calcium supplements. However, in July 2012, The Oncologist published a study that stated the ineffectiveness of calcium supplements in preventing bone loss. In fact, the patients’ prostate cancer even become more aggressive. Twelve clinical trials were reviewed by North Carolina’s Wake Forest Baptist Medical Center researchers. Their findings, which were based on the hormone-deprivation therapy of 2,400 male prostate cancer patients, included a decrease in the patients’ bone density despite calcium supplements intake and a higher risk for the aggressive development of prostate cancer.
