Vitamin E Shows Potential for Prostate Cancer Prevention
A new animal study has found new evidence that vitamin E may help prevent prostate cancer. The findings of the study were published in the July 2010 issue of the journal Nutrition and Cancer.
Researchers from Rutgers, the State University of New Jersey used approximately 40 mice for the study. All of the mice were 8 weeks old at the beginning of the study, and all came from a strain of mice that are genetically wired to develop prostate cancer.
The mice were divided into 5 separate groups and were fed the same diet. 3 of the groups were also given 0.1%, 0.3%, or 1% of a combination of four forms of vitamin E. They remained on this vitamin E supplemented diet for 24 weeks.
By the end of the study 73% of the mice in the control group developed palpable tumors compared to between 22% and 38% in the groups given the vitamin E supplement.
The mice taking the vitamin E supplemented diet also saw the suppression of high-grade prostatic neoplastic lesions to fully developed tumors. These lesions are an abnormality of the prostate glands, and are believed to precede the development of prostate cancer.
This study adds to a growing body of science linking vitamin E with prostate cancer prevention. The researchers plan to conduct further studies with humans to determine if vitamin E also acts as a preventative measure in humans.
Currently over half a million men are diagnosed with prostate cancer every year and over 200,000 deaths result from the disease yearly.
Beyond consuming more vitamin E, eating a low fat diet, consuming more foods high in antioxidants (especially green tea) and consuming more omega-3 fatty acids are other ways to potentially lower your prostate cancer risk.
