[阅读理解]

【题干】We have heard a lot about the health benefits of tea, especially green tea. It is high in poly-phenols, compounds with strong antioxidant activity that in test-tube and animal models show anti-cancer and heart-protective effects. Good clinical studies are few, however, and although physi-cians tell their patients to drink green tea, there hasn 't been any definite proof of the value of that advice.
A team of Japanese researchers was able to link green tea consumption with decreased mortali-ty from many causes- -including heart disease. The researchers tracked 40，530 healthy adults ages 40 to 79 in a region of northeaster Japan where most people drink green tea, following them for up to 11 years. Those who drank five or more cups of green tea a day had significantly lower mor-tality rates than those who drank less than one cup a day. There were also fewer deaths from cardiovascular disease.

[A] young adults
[B ] Asian people
