Diet May Help Fight Prostate Cancer
 (Washington, AP, 8/11/05)

Dr. Dean Ornish and associates at the University of California, San Francisco, recruited 93 men who had chosen the option of “watchful waiting” for their early-stage, non-aggressive prostate cancer. The researchers randomly assigned half of the subjects to follow Ornish’s lifestyle regimen, which includes a vegetarian diet, severe limitation of fat intake; exercise and stress management. The others maintained their usual habits. When PSA (prostate specific antigen) tests were performed on the participants’ blood, the investigators found that, after a year, those on the Ornish regimen had a 4% drop in PSA levels, which is “unusual for untreated patients.” On the other hand, PSA levels rose an average of 6% for the control group. In addition, six of the controls had undergone conventional treatment because their cancer was progressing; whereas none on the Ornish regimen underwent such treatment. The scientists will continuing tracking the men to gauge longterm effects.
