Vitamin D and Calcium: What You Need To Know
Posted by admin on Jun 26, 2008
Every year many people die from stroke, heart attack and a host of other cardiovascular diseases. These diseases may stem from bad diet, unhealthy lifestyle, being overweight and basically not getting enough vitamins and minerals in the body such as Vitamin D and calcium.
Recent Studies show that enough Calcium and Vitamin D intake lowers the risk of dying from cardiovascular diseases and generally helps prevent many other health problems. A research led by Harald Dobnig, MD, of the Medical University of Graz, Austria, studied 3,258 patients with heart problems. The patients composed of both men and women were monitored for eight years.
After eight years, preliminary studies show that those with lower levels of Vitamin D had a higher risk of dying from cardiovascular diseases. Although the tests results were not conclusive, it was enough to show the link of low vitamin D intake to cause higher risk of dying from these diseases. In another study, calcium was also said to have the same effect.
