“A critical weekly review of important new research findings for health-conscious readers”
VITAMIN D, CARDIOVASCULAR DISEASE, CANCER AND DEATH
Among all of the vitamins, only Vitamin D appears to have clinically significant health benefits in reducing the risk of death associated with cardiovascular disease, fractures, and cancer, based upon numerous recent clinical research study findings (for a comprehensive update on the role of Vitamin D as part of a cancer prevention lifestyle, please see my new book, A Cancer Prevention Guide for the Human Race, which is now available from Amazon and Barnes & Noble).
A newly-published clinical research study, which appears in the current issue of the American Journal of Clinical Nutrition, prospectively evaluated 1,194 elderly men (average age was 71 years) over a period of nearly 13 years. Blood levels of Vitamin D were measured in these elderly male men, and the results of these blood tests were then correlated with subsequent health outcomes.
In this prospective public health study, with extensive long-term follow-up, very low and very high blood levels of Vitamin D were associated with a significantly increased risk of death. In fact, a whopping 50 percent increase in the risk of death was associated with both very low (<46 nmol/L) and very high (>98 nmol/L) concentrations of Vitamin D in the blood. Death due to cancer was two times more common with very low Vitamin D levels, while very high levels of Vitamin D increased the risk of death due to cancer by almost three-fold. At the same time, death due to cardiovascular disease was nearly twice as likely in elderly men with very low Vitamin D levels, but not in men with very high levels of this hormone-like vitamin.
The findings of this prospective public health study add to the enormous volume of previously published clinical research data on the health effects of Vitamin D. As this study suggests, there may be an optimal concentration of Vitamin D in the blood that is associated with a decreased risk of death from both cardiovascular disease and cancer. Meanwhile, a healthy diet that emphasizes fresh fruits, brightly-colored fresh vegetables, whole grains, and fatty fish (and minimal red meat and other animal-based foods) is your best bet for a long and healthy life!
