"The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation...As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes...After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off... The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down... The research was led by Dr. Dean Ornish, head of the Preventive Medicine Research Institute in Sausalito, California, and a well-known author advocating lifestyle changes to improve health..."often people say, 'Oh, it's all in my genes, what can I do?' Well, it turns out you may be able to do a lot"..." "'In just three months, I can change hundreds of my genes simply by changing what I eat and how I live?"..."

Showing yet again how pliable our genome is. If this story doesn't further the message that genes are not a fixed fate, I'm not sure what will.
