The study was conducted at the non-profit Preventive Medicine Research Institute and followed 500 men diagnosed with Prostate Cancer. The men, for reasons unrelated to the study, were not receiving any other treatments at the time. They changed their eating habits to mostly plant-based foods (fruits & veggies, soy, legumes, whole wheat), walked for 30 minutes per day, did one hour of yoga-type stretching or meditation each day, and met once a week for a group support session.
"After three months, we repeated the biopsy and looked at changes in normal tissue within the prostate. We found that many disease-promoting genes (including those associated with cancer, heart disease, and inflammation) were down-regulated or "turned off," whereas protective, disease-preventing genes were up-regulated or "turned on." For example, a set of cancer-promoting oncogenes called RAS was down-regulated in these men. The Selectin E gene (which promotes inflammation and is elevated in breast cancer) was down-regulated. Another gene that suppresses tumor formation called SFRP was up-regulated, thereby reducing the risk of cancer. These genes are the target of many new drugs that are being developed. Clearly, changing lifestyle is less expensive, and the only side-effects are good ones. "
Because the study looked at the healthy tissue, not cancerous tissue, it is likely that the results can be generalized beyond just men with prostate cancer. The end of the era of genetic nihilism is upon us.
