Green tea and cancer prevention

19-08-2013

Written by Sally Shi Po Poon (Registered Dietitian)

Green tea contains the active ingredient polyphenol, which has a subgroup known as catechins. Catechins are powerful antioxidants and may have cancer-preventative effects. A large study in Japan found that males aged between 40 and 69 who drank five cups of green tea daily were less likely to develop advanced prostate cancer than those who drank only one(1). 

However, despite promising results of the current study, it does not provide strong enough evidence that green tea can definitely reduce the risk of prostate cancer. This is due to the differences between the people who drank green tea frequently and those who drank it occasionally such as their eating habits and lifestyles. 

There is insufficient and conflicting evidence to give any firm recommendations regarding green tea consumption for cancer prevention by far(2). Overall, drinking green tea appears to be safe at moderate, regular and habitual use. Those who enjoy a cup of green tea should continue its consumption.
