A leading expert on lifestyle and nutrition spoke to the Army War College Class here Sept. 9 as a component of the Senior Leader Development & Resiliency Program. "… Eat well, stress less, move more and love more," was the overarching message that cardiologist Dr. Dean Ornish presented to the class. He emphasized that looking at underlying causes is key to good health and healing, rather than treating the symptoms which often return.Learn what the Army War College officers and civilian leaders learned about healthy lifestyles for those with significant leadership responsibilities.

His own study with men diagnosed with prostate cancer showed that healthy choices could slow, stop or even reverse tumor growth. "The more people changed, the more they improved," said Ornish. This prompted Ornish to take the next step and study the mechanisms that might explain these results. "We looked at their gene expression," said Ornish. "What we found was that 501 genes were changed. When you change your lifestyle it actually changes your genes." A healthier lifestyle turns on the genes that protect you and turns off the genes that cause prostate or breast cancer, he explained. Even meditation can positively affect gene expression. Elite athletes meditate to gain a competitive advantage, and meditation also calms your mind, said Ornish."When you can focus your awareness, you gain power. You can perform better on the battlefield, in the [school room] and the boardroom," said Ornish.Dr. Ornish is the founder and president of the Preventive Medicine Research Institute and a clinical professor of medicine at the University of California, San Francisco.
