Vegan Diet Puts Brakes on Prostate Cancer
A combination of a vegan diet, regular exercise, and stress management caused prostate-specific antigen (PSA) levels to retreat in a group of prostate cancer patients, according to new data presented by Dean Ornish, M.D., at the Scientific Conference on Complementary, Alternative and Integrative Therapies at Harvard University on April 13, 2002. In the 42 men assigned to an untreated control group, PSA levels rose over the three-month study period, and seven required additional treatment. But, in the 42 men assigned to the diet and lifestyle intervention, the average PSA level dropped from 6.3 to 5.8, and none required further treatment.
