A new pilot study shows that eating right, exercising and reducing
stress may help keep chronic diseases at bay by switching on beneficial genes, including tumor-fighters, and silencing those that trigger malignancies and other ills.
"We found that simple changes have a powerful impact on gene expression," Dean Ornish, founder and president of the Preventive Medicine Research Institute and clinical professor at the University of California, San Francisco (U.C.S.F.), said during a news conference. "People say, 'Oh, it's all in my genes, what can I do?' That's what I call genetic nihilism. This may be an antidote to that. Genes may be our predisposition, but they are not our fate."
