Vitamin D for Breast and Colon Cancer Protection

Two new studies suggest that up to half of all cases of breast cancer and two thirds of all cases of colorectal cancer in the United States could be prevented with vitamin D supplements and a little bit of sun exposure. For the breast cancer study, researchers at the University of California, San Diego pooled data from two big studies, the Harvard Nurses' Health Study and the St. George's Hospital Study, and found that participants with the highest blood levels of vitamin D had the lowest risk - half the cancer incidence of those with the lowest vitamin D levels. For the colorectal study the same investigators analyzed data from five studies. In all the studies, blood samples were taken from healthy volunteers who then were followed for up to 25 years. Here, too, those with the highest blood levels of vitamin D were half as likely to develop colorectal cancer as those with the lowest blood levels. Researchers projected that raising the vitamin D level even higher would cut risk by two-thirds. To cut your risks of both types of cancer the investigators recommended taking 2,000 IU of vitamin D3 daily and spending 10 to 15 minutes in the sun daily when the weather permits.
