U.S. researchers have found links of consumption in high doses of calcium with increased risk of death from cardiovascular disease, reports Medical News Today. New data held by a group of scientists led by Xiao Qian (Qian Xiao) from the National Cancer Institute (National Cancer Institute, Bethesda, MD), were published in JAMA Internal Medicine.
Study of Xiao Qian and his colleagues involved analysis of the results of a large study (NIH-AARP Diet and Health Study), participants were 388,229 people. Experts watched volunteers aged 50 to 71 years for 12 years. Over the entire study period, they were only more than ten thousand deaths (3,874 women and 7,904 men) from cardio-vascular diseases. In this case, 51 percent of men and 70 percent of women who participated in the study were taking supplements containing calcium.
As it turned out, the risk of death from heart disease in men who consumed a day more than 1,000 milligrams of calcium tablets (but not with food), was 20 percent higher. This result includes an increase in the risk of death from heart disease by 19 percent and from diseases caused by cerebral blood flow by 14 percent. For women between increased calcium intake and mortality from diseases of the cardiovascular system is no relationship was found.
Contact increasing risk of death from cardiovascular disease, as the authors note, the consumption of calcium by sex to check for additional studies.
