Up to 60% lower incidence
Researchers interviewed 753 prostate cancer patients and 703 healthy men in the Seattle area. The data showed that men who consumed four or more glasses of red wine per week reduced their risk of prostate cancer by 50%. Among men who consumed four or more four-ounce glasses of red wine per week, there was a 60% lower incidence of the more aggressive types of prostate cancer. The scientists found that it was in the more clinically aggressive prostate cancer where the strongest reduction in risk was observed.
The study found that beer, hard liquor, and white wine had no impact on prostate cancer risk.
