1. A study from the Harvard T.H. Chan School of Public Health followed 926 men aged 40 to 84 who were diagnosed with prostate cancer, but whose cancer had not yet spread. The patients were monitored for approximately 10 years. The diet of the patients was analyzed 5 years after the diagnosis of the prostate cancer using detailed questionnaires. Men who followed a Westernized diet with red meat, refined grains, high-fat dairy products and processed foods had a probability of dying that was 2.5-times higher than men who were on the healthiest diet. In terms of dying from any cause the men on the Westernized diet had a 1.5- fold higher risk than the men on the healthiest diet.
The same recommendations that are made regarding prevention of cardiovascular disease to the general public are the very same dietary recommendations that helped men with diagnosed, but localized prostate cancer to keep the prostate cancer from spreading and killing the patients.
Dr. Jorge Chavarro, the lead investigator said that men who have been diagnosed with prostate cancer should choose a Mediterranean type diet with vegetables and fruit, fiber and less dairy products and meat. This will help them improve their chances of survival.Another study published in Cancer Prevention Research (April 14, 2015) found that green tea catechins in capsule form were effective in preventing the development of prostate cancer in 23 of 26 men; at the time of enrolment into the study they all had high-grade prostatic intraepithelial neoplasia and three men developed prostate cancer after one year of observation. In the control group who only received placebo pills 10 men came down with prostate cancer. The patients on green tea catechins also had a reduction of their PSA (a prostate marker) values in comparison to the placebo group.
2. The question is how the Mediterranean diet compared to the Standard American diet can protect men from prostate cancer. And the same question can be asked regarding the green tea catechins. At the 23rd Annual World Congress on Anti-Aging Medicine in Las Vegas (Dec. 11-13) Dr. Mark Rosenberg may have answered this question. He spoke about the ENOX-2 gene located on the X-chromosome, which is only expressed during embryogenesis and then in adulthood only again when cancer develops. A test has been developed to check for the ENOX-2 gene, which becomes positive 5 to 7 years before cancer can be detected clinically. This is called Oncoblot test. As sensitivity of ENOX-2 is high and false positives are negligible, this makes the ENOX-2 marker ideal for cancer screening. There are various isoelectric points for various cancer tissues, so the lab physician can tell the treating physician from which tissue a positive cancer test originates. The interesting thing is that a combination of green tea and capsicum has been able to suppress the expression of the gene, and the cancer gene was turned off. Corresponding biopsy samples showed that the cancer cells had disappeared. This is an entirely new concept.
We are entering a new era, where cancer is seen from a different angle. It appears that there are cancer inducing foods and chemicals (called carcinogens) that turn cancer genes like the ENOX-2 gene on. But there are other substances like catechins in green tea and capsicum (derived from hot pepper) that can turn off cancer genes (like the ENOX-2 gene). In this light the effect of green tea in the second trials described above and the effect of the Mediterranean diet regarding the first trial seem to make more sense. It underlines the old principle that prevention is more powerful than any attempt to heal.
