Up close and edible:Green tea
　　Green tea is one of the most popular beverages to hit the U.S. market in the last decade. Unlike black tea or oolong, green tea is made from unfermented tea leaves. Because it does not go through a fermentation process, research suggests that it contains the highest concentration of polyphenols, antioxidants that rid of the body of free radicals. Some preliminary research shows that green tea’s polyphenols, particularly ECGC, stop the free-radical damage that may lead to cancer and heart disease.
　　But even though green tea gets a lot of props for its reputation as a healing brew, most of the studies on its effects have been done in the laboratory or in animals. The bulk of human studies have been population-based, those that follow large groups of people over a specified period of time. The results of those studies have been inconsistent. Because of that data, the Food and Drug Administration says there is no scientific evidence that drinking green tea reduces heart disease, and the agency rejected a petition last year that sought to allow the claim on tea labels. The FDA previously said that green tea probably does not reduce the risk of breast, prostate or any other type of cancer. “Green tea has a lot of wonderful active compounds that may play a role in fighting cancer and heart disease and even protecting the lining of the arteries,” says Dave Grotto, spokesperson for the American Dietetic Association. “But there needs to be a lot more research.”
　　Despite many claims to the contrary, it probably doesn’t help with weight loss, either. Some studies suggest that green tea’s polyphenols may boost metabolism and help burn fat. Unfortunately, “there’s nothing magic about green tea,” says Dr. Frank Greenway, head of the outpatient clinic at the Pennington Biomedical Research Center in Baton Rouge, La., who studies herbal supplements and obesity. “I’ll be surprised if it is shown to have any profound effect on weight loss.”
　　Don’t throw out your green tea just because the studies have been less than impressive. “Herbs always play catch-up when it comes to research,” says Greenway. “Green tea won’t hurt you.” And maybe it will do some good. Some studies show that some green-tea drinkers may actually get more health benefits than others. Try it freshly brewed, which provides more antioxidants than bottled green-tea drinks.

　　背景常識介紹：
　　近幾年,越來越多的科學(xué)研究資料表明了茶葉的營養(yǎng)價值及保健作用、如抗癌作用、降血脂、減肥、預(yù)防心血管疾病、抵抗輻射、抗氧化、延緩衰老、增進精神健康、助消化、護齒、護膚等等。
　　參考譯文：
　　綠茶面面觀
　　綠茶是近十年來沖擊美國市場的最流行的飲料之一。和紅茶與烏龍茶不一樣的是，綠茶是由沒有發(fā)酵過的茶葉制成的。因為它沒有經(jīng)過發(fā)酵處理，研究表明它富含茶多酚以及去除人體自由肌的抗氧化劑。某些初步研究表明，綠茶的茶多酚，尤其是ECGC可以防治可能導(dǎo)致癌癥和心臟病的自由肌對于人體的損壞，考試大。
　　雖然綠茶有很多好處使它享有保健品的美譽，但是，對于它的影響的實驗仍然在實驗室或者動物身上大量進行著。以人為實驗對象這一塊，是以特定時期的特定人群為基礎(chǔ)的，但是，實驗的結(jié)果卻是不一致的。因此，根據(jù)這一數(shù)據(jù)，食品和藥品管理局表示稱喝綠茶可以減少心臟病是沒有科學(xué)根據(jù)的，并且拒絕了去年要求把這一說法寫在茶葉包裝上的申請。FDA在這之前就提出過，綠茶很有可能不會降低乳腺、前列腺或者任何其他癌癥的風(fēng)險。美國食品衛(wèi)生聯(lián)合會的發(fā)言人Dave Grotto表示：“綠茶里含有很多大量的非常棒的人體所需的化合物，這些化合物可能對預(yù)防癌癥及心臟病起到一定的作用甚至?xí)Ｗo我們的動脈內(nèi)壁。當(dāng)然，這些結(jié)論都還需要更多的研究來給予證明。”
　　綠茶似乎也并不能幫助減肥，雖然，也有很多說法與之相反。有一些研究表示，綠茶的茶多酚可能會加快新陳代謝以幫助燃燒脂肪。但是，非常不幸的是，美國路易斯安那州巴吞魯日Pennington生物醫(yī)學(xué)研究中心，研究草藥補給與肥胖的臨床門診部主任Frank Greenway博士說：“綠茶沒有任何神奇之處。如果它對減肥有任何實質(zhì)性的影響的話，我將會感到驚訝不已。”
　　不要因為研究所表明的證據(jù)不足就把綠茶給扔了。Greenway說：“對草藥的研究結(jié)果總是表現(xiàn)的姍姍來遲，綠茶是不會有壞處的”。也許它還有某些好處。某些研究結(jié)果表明一部分喝綠茶的人的確要比不喝綠茶的人身體健康。新鮮的綠茶要比瓶裝的綠茶含有更多的抗氧化劑。
