Calcium and Vitamin D Can Help Postmenopausal Women
Research in the June 2007 issue of the American Journal of Clinical Nutrition has shown a reduction in cancer rates among postmenopausal women taking vitamin D combined with calcium.
This four-year, double blind, randomized placebo-controlled study involved over 1,100 postmenopausal women who were divided into three treatment groups. The first group received a supplement containing calcium and vitamin D, the second group received just calcium, and the third group received a placebo. The researchers found that the women taking the calcium and vitamin D supplement had a 60 percent lower incidence of all cancers than women not taking the supplement.
This study takes an important step in extending several decades of research involving the role of vitamin D in health and disease. The results further strengthen the case made by many specialists that vitamin D may be a powerful cancer preventive and that it is commonly found lacking in the general population, particularly the elderly.
