In men with recurrent prostate cancer, drinking 8 ounces per day of pomegranate juice significantly increases the time it takes for prostate specific antigen (PSA) levels to rise, according to research presented Monday at the annual meeting of the American Urological Association in San Antonio.Before the men in the study began consuming pomegranate juice, the average PSA doubling time, a measure of tumor activity, was 15 months, lead author Dr. Allan J. Pantuck, from the University of California at Los Angeles, told Reuters Health. “The average time after treatment was 37 months. So, there was almost a 2-year increase in the doubling time."Pomegranate juice contains a number of antioxidants thought to have anti-cancer effects, Pantuck noted. In addition, the juice contains estrogen-like plant substances called phytoestrogens that could be useful in combatting prostate cancer, in particular.
