 Prostate cancer strikes 200,000 men each year and kills 29,000. Diet may play an important role in the incidence and risk of death from the disease. A review of literature by J.J. Johnson from the University of Wisconsin and colleagues concluded that green tea extract might reduce the risk of prostate cancer. Green tea is high in antioxidants such as flavonoids and phenolic acids. Asian men who drank a lot of green tea and then moved to the United States increased their risk of prostate cancer when they consumed a Western diet and cut down on green tea intake. The authors cited five studies showing that green tea extract reduced the risk of prostate cancer. A critical issue is the amount of flavanoids and phenolic acids contained in the tea or extracts. Levels must be high enough to suppress cancer cell growth. (Phytomedicine, 17: 3-13, 2010)
