"Dear A Moment Of Science, Can you settle a debate between my friend and me?
親愛的科學(xué)一刻,您能否解決我和朋友之間的一場(chǎng)爭(zhēng)論么？
She says thatgreen tea has some magic property that fights cancer.
她說(shuō)綠茶具有抗癌的魔力，我覺得這不切實(shí)際。
I say this is bogus. What's the scoop?"
事實(shí)的真相到底如何呢？
Well, it's not magic, but it can help in the fight against cancer.
它當(dāng)然沒(méi)有魔力，但是的確有助于抗癌。
Studies have shown that peoplewho drink green tea develop fewer cancerous tumors, and animal studies also support this idea.
研究顯示，喝綠茶的人激發(fā)惡性腫瘤較少，動(dòng)物研究也支持這一說(shuō)法。
Some researchers at Purdue University have a guess why.
普渡大學(xué)的一些研究者對(duì)此進(jìn)行了猜想。
Green tea contains a powerful antioxidant called EGCg, whose full name is just too darn long to write out.
綠茶包含了一種有效的抗氧化物茶多酚，這里就不贅述其冗長(zhǎng)的全名了。
But this chemical seems to counteract an enzyme called quinol-oxidase.
但這種化合物似乎可以抑制苯二酚氧化酶。
That's anenzyme cancer cells need in order to reproduce.
復(fù)制癌細(xì)胞需要用到這種酶。
When they can't reproduce, cancerous cells dieoff instead of becoming dangerous.
若癌細(xì)胞無(wú)法復(fù)制，它們就會(huì)消亡從而不（對(duì)人體）造成威脅。
Green tea isn't the only beverage that contains EGCg; black tea has it as well, just not as much of it.
綠茶并非唯一含有茶多酚的飲料；紅茶也包含這種物質(zhì)，只是沒(méi)那么多。
Again, there's no magic pill for avoiding cancer.
再次澄清一下，沒(méi)有避免癌癥的神奇藥片。
Drinking green tea may be a good counter-measure, but bear in mind that it takes a lot to get the possible benefit.
喝綠茶可能是一個(gè)好對(duì)策，但記住，這可需要喝很多才能起效。
And of course there is theold stand-by good-health stuff: diet and exercise.
當(dāng)然，還得佐以老生常談的健康措施：均衡飲食，合理運(yùn)動(dòng)。
