Some potentially good news for us vegan men. A new study by Dr. Dean Ornish suggests that a low fat vegetarian diet coupled with exercise and stress management techniques, like yoga, actually shuts down prostate cancer triggering genes and stimulates cancer preventing genes. What is the science behind it, and how does it all work? I have no idea. You can link to the news story I saw here and here, and to the study itself here. If Ornish's findings are correct, this means good things for exercising, yoga-doing, plant-eating men like myself.
