Green Tea Tied to Reduced Digestive System Cancers in Older Women

A study of more than 69,000 Chinese women found that older women who regularly drink green tea might have slightly lower risks of developing digestive system cancers.

The women, who drank green tea at least three times a week, were 14 percent less likely to develop colon, stomach or throat cancer.

The researchers also refer to "strong evidence" from other animal and human studies that seemed to point to green tea having the potential to fight cancer.

Green tea is considered safe in moderate amounts, but the tea and its extracts do contain caffeine, which some people need to avoid. Green tea also contains small amounts of Vitamin K, which can interfere with warfarin and other drugs that prevent blood clots. Older people are encouraged to talk to their doctors before using green tea as a health tonic.
