"Dear A Moment Of Science, Can you settle a debate between my friend and me?
She says thatgreen tea has some magic property that fights cancer.
I say this is bogus. What's the scoop?"
Well, it's not magic, but it can help in the fight against cancer.
Studies have shown that peoplewho drink green tea develop fewer cancerous tumors, and animal studies also support this idea.
Some researchers at Purdue University have a guess why.
Green tea contains a powerful antioxidant called EGCg, whose full name is just too darn long to write out.
But this chemical seems to counteract an enzyme called quinol-oxidase.
That's anenzyme cancer cells need in order to reproduce.
When they can't reproduce, cancerous cells dieoff instead of becoming dangerous.
Green tea isn't the only beverage that contains EGCg; black tea has it as well, just not as much of it.
Again, there's no magic pill for avoiding cancer.
Drinking green tea may be a good counter-measure, but bear in mind that it takes a lot to get the possible benefit.
And of course there is theold stand-by good-health stuff: diet and exercise.
译文：
"亲爱的科学时刻，你能解决我和我朋友之间的辩论吗？
她说绿茶有一些神奇的特性，可以抗击癌症。
我说这是假的。有什么秘诀吗？"
好吧，这不是魔术，但它可以帮助抗击癌症。
研究表明，喝绿茶的人患癌症的肿瘤较少，动物研究也支持这一观点。
普渡大学的一些研究人员猜到了原因。
绿茶含有一种叫做EGCg的强大抗氧化剂，其全名太长，无法写出来。
但这种化学物质似乎能抵消一种叫做喹啉氧化酶的酶。
那是一种癌细胞需要的酶，以便繁殖。
当它们不能繁殖时，癌细胞就会消亡，而不是变得危险。
绿茶不是唯一含有EGCg的饮料；红茶也有EGCg，只是含量没有那么多。
同样，没有避免癌症的神奇药丸。
喝绿茶可能是一个很好的对策，但要记住，需要很多才能获得可能的好处。
当然还有老生常谈的有益健康的东西：饮食和运动。
