An interesting article I found via the Torygraph of all places:
Vegan diet and yoga fight cancer
By Roger Highfield, Science Editor
“A vegan low fat diet combined with yoga and exercise can help fight prostate cancer, new findings show.
Researchers found that combining a diet low in fat and rich in fruit and vegetables with regular moderate exercise seems to switch on genes that fight disease, while effectively turning off others that can promote cancer.
The evidence that genes are not your fate, undermining what the authors call “genetic nihilism,” comes from a study of men with early stage prostate cancer but could be of relevance to a wide range of cancers, such as breast cancer.
This is according to Dr Dean Ornish, founder and president of the non-profit Preventive Medicine Research Institute and clinical professor of medicine at the University of California, San Francisco.
Inspired by studies that show prostate cancer is rarer in parts of the world where people eat a predominantly low-fat plant-based diet, he devised a vegan diet for patients, along with exercise, and a resulting “striking” effect on the way genes are used in the body is reported in the Proceedings of the National Academy of Sciences by Prof Ornish, working with Dr Christopher Haqq and Prof Peter Carroll….
… Ed Yong, health information manager at Cancer Research UK, said: “People often think that their odds of getting cancer are written in their genes. But studies like this suggest that changing your lifestyle can change the activity of your genes, and that nature can be changed by nurture.
“This study tells us that men with low-risk prostate cancers can change the levels of certain genes that are relevant to cancer by making positive lifestyle changes, like keeping active, eating a healthy, balanced diet and managing their stress levels.
