Physical exercise can change the DNA in certain genes that stimulate obesity and lessen their effects by about 30%. Epigenetics has a lot to do with how the DNA in our genes manifests itself. This challenges the widely held belief that what is in our DNA is not changeable...thank goodness that this is not true.
We have found the same epigenetic changes with heart disease and with prostate cancer. Studies have shown that a diet high in fruits and vegetables lowers the risk for progression of coronary artery disease. We also know that the oncogenes stimulating prostate cancer can be turned off by health lifestyle changes.
