Answer

Some research suggests that drinking pomegranate juice may slow the progression of prostate cancer.

For example, in one study, the length of time it took for prostate-specific antigen (PSA) to double after surgery or radiation for prostate cancer was significantly longer in men who drank 8 ounces (237 milliliters) of pomegranate juice daily for up to two years. A longer PSA doubling time indicates that the cancer may be progressing less rapidly. Other studies have found that certain compounds in pomegranate juice inhibited growth of prostate cancer cells in the laboratory.

Although these results are encouraging, they're only preliminary. Clinical trials are under way, and it's too early to say if pomegranate juice can definitely slow the growth of prostate cancer. It's also unclear whether drinking pomegranate juice alters the course of prostate cancer overall so that men live longer or better.

If you choose to drink pomegranate juice, talk with your doctor first. Although pomegranate juice is generally safe, there is evidence that it affects the metabolism of several prescription medications, including the blood thinner warfarin (Coumadin) and some drugs used to treat high blood pressure and high cholesterol.
