Calcium heart attack link is found

CALCIUM supplements, taken by millions of elderly people and postmenopausal women to prevent bone thinning, may double the risk of having a heart attack, a study has found. Researchers warned that the pills should be “taken with caution”, and experts commenting on the findings questioned their safety. Previous studies linked higher calcium intake with a reduction of heart disease risk factors such as high blood pressure, obesity andtype 2 diabetes. But the new research from Germany points to a vital difference between dietary calcium from sources such as milk, cheese, greens and kale, and supplements.
