(NaturalNews) 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.
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.
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`.
Scientists found that the two nutrients work synergistically to lower cancer risk in aging healthy women. The authors conducting the study concluded, "these findings highlight the importance of promoting optimum vitamin D status and underscore the value of achieving and maintaining a high serum 25(OH)D concentration." This study demonstrates the importance of maintaining multi-nutritional status to prevent chronic illness.
Vitamin D is only one of a very small number of natural nutrients that are known to prevent and treat many types of potentially life-threatening conditions. Up until the age of 40 sun exposure provides the best source of vitamin D, but conversion of the nutrient declines as we age and supplementation using an oil-based gelcap is necessary to maximize blood saturation and lower cancer risk.
