The field of epigenetics is exploding. We now know that DNA changes in response to environmental exposures and causes major changes in gene expressivity. It is well known that prostate cancer genes (oncogenes) are turned on and off by diet, exercise, relation, sleep, meditation and more. The work of Dean Ornish, MD on prostate cancer proved this. We now have evidence that eating a diet high in fruits and vegetables can significantly weaken the effect of a gene that increases the risk for heart disease.
