Don’t Ignore Vitamin D to Dramatically Slash Cancer Risk
Evidence in support of the health-promoting properties of vitamin D continues to mount as new research shows a direct link between blood levels of the super-nutrient and the risk of developing colon cancer. The National Cancer Institute provides statistics showing that colon cancer is the second most deadly form of the disease, taking the lives of more than 50,000 each year in the US. The International Journal of Cancer has published a meta-analysis from nine comprehensive studies showing dramatic reductions in colon cancer risk with higher blood concentrations of the sunshine vitamin.
Cancer Risk Reduction is Linked to Vitamin D Blood Saturation
The pooled data from the studies reviewed showed that for every 10 nanograms per milliliter increase in vitamin D blood level saturation, there was a corresponding decrease in colon cancer incidence of 15%. Breast cancer risk was lowered by 11% with the same increase in vitamin D. Researchers made note that they were testing the biologically active form of vitamin D known as cholecalciferol (vitamin D3) and not the less active precursor (vitamin D2 or ergocalciferol). Vitamin D was tested using the more accurate 25(OH)D blood test.
The role of vitamin D in cancer prevention has been theorized since the early 1940`s when scientists discovered that cancer rates were much lower in countries closest to the equator. At the time they believed that sunshine played an important role in `cancer immunity`. Over time the link between vitamin D production in the skin and sun exposure has become increasingly apparent and extensive research demonstrates how this crucial nutrient can protect DNA integrity and prevent cancer-causing mutations.
Ensure Proper Vitamin D Levels With a Simple Blood Test
Research studies over the past decade have provided conclusive evidence that vitamin D blood levels in the 50 to 80 ng/ml range are associated with a significantly reduced cancer risk from all lines of the disease. The American Journal of Clinical Nutrition published the results of a study showing that vitamin D (1100 IU per day) combined with calcium (1400 to 1500 mg per day) `substantially reduces all-cancer risk in postmenopausal women`.
