Researchers conclude that vitamin supplements are probably useless for heart disease and cancer prevention, but how true is that?
It seems that NBC News has demonstrated their investigative journalistic incompetence in reporting that ‘vitamins don’t prevent heart disease or cancer’. As Dr. Andrew Saul, editor of the Orthomolecular Medicine News Service, points out “NBC's supplement-bashing headline article... displays an ignorance of clinical nutrition that is difficult to ignore, and, thanks to its media prominence, can't be.”
Dr, Saul brings to attention the following studies that clearly show that vitamin supplements do have positive effects:
- JAMA 2012: Multivitamin supplements were found to reduce cancer risk by 8%.
- International Journal of Cancer 2011: A mere 10 ng/ml increase in serum vitamin D levels was associated with a 15% reduction in colorectal cancer incidence and 11% reduction in breast cancer incidence.
- International Journal of Cancer 2011:10 While the NBC declared that “Vitamin E does no good at all in preventing cancer or heart disease,” this study found that gamma-tocotrienol, a cofactor found in natural vitamin E preparations, decreases prostate tumor formation by a respectable 75%.
- International Journal of Cancer 2008: Here, 300 IUs of vitamin E per day reduced lung cancer risk by 61%.
There are a growing number of studies showing that vitamin D has tremendous protective effect against cancer. A study published in the American Journal of Preventive Medicine concluded that a serum 25(OH)D level of more than 33 ng/mL was associated with a 50% lower risk of colorectal cancer.
Another study published in the American Journal of Clinical Nutrition found that after four years of follow up, cancer-free survival was 77% higher in women who received 1,100 IU vitamin D and 1,450 mg calcium per day, compared to those who received either a placebo or calcium by itself. Theories linking vitamin D deficiency to cancer have been tested and confirmed in more than 200 epidemiological studies, and understanding of its physiological basis stems from more than 2,500 laboratory studies.
Research has shown that optimizing your vitamin D levels can reduce your risk for as many as 16 different types of cancer, including pancreatic, lung, ovarian, breast, prostate, and skin cancers.
A recent report on vitamins produced by the Council for Responsible Nutrition Foundation, titled: “Smart Prevention—Health Care Cost Savings Resulting from the Targeted Use of Dietary Supplements”concluded that, based on the scientific evidence of benefit, supplementation at preventive intake levels could save the American healthcare system more than $11 BILLION each year.
So there is absolutely no doubt about the positive effects of vitamin supplementation. Anybody concerned about cancer should be aware of the benefit of supplementing with Vitamin D.
