Effect of 'Northern California' diet on PCa may be known soon

What have we learned from the work of Dean Ornish, MD about the effect of diet on prostate cancer prevention?
Session moderator Peter Carroll, MD, of the University of California, San Francisco, referred to a study he co-authored with Dr. Ornish (J Urol 2005; 174:1065-9).

"Men on a low-fat vegetarian diet, taking supplements, exercising, reducing stress-your typical Northern California approach to disease management-lowered their PSAs a bit and were less likely to require treatment than those men who were not on intervention," Dr. Carroll said.

"We are close to finishing a randomized trial focusing on gene expression, and those results will hopefully be reported in the next 3 months," he added. "That will really tell us whether the use of supplements or lifestyle intervention changes the prostate cancer micro-environment based on serial gene expression analysis."
