Prevent Cancer, Use Olive Oil: New Year's Resolution No. 1
预防癌症，食用橄榄油：新年决心的首选
If you want to avoid developing cancer, then you might want to add eating more olive oil to your list of New Year's resolutions. In a study to be published in the January 2007 issue of The FASEB Journal, scientists from five European countries describe how the anti-cancer effects of olive oil may account for the significant difference in cancer rates among Northern and Southern Europeans.
如果你想避免癌症的发生，那就把多食用橄榄油列入你的新年决心吧。在即将发表的2007年元月刊的FASEB杂志上，来自欧洲5个国家的科学家发表了有关橄榄油抗癌作用与北欧和南欧不同癌症发病率之间关系的文章。
The authors drew this conclusion based on the outcomes of volunteers from Denmark, Finland, Germany, Italy, and Spain, who consumed 25 milliliters (a little less than a quarter cup) of olive oil every day for three weeks. During this time, the researchers examined urine samples of the subjects for specific compounds known to be waste by-products of oxidative damage to cells, a precursor to cancer. At the beginning of the trial, the presence of these waste by-products was much higher in Northern European subjects than their Southern European counterparts. By the end of three weeks, however, the presence of this compound in Northern European subjects was substantially reduced.
文章作者的结论基于对来自丹麦、芬兰、德国、意大利和西班牙志愿者为期3周的研究，期间他们每日食用25毫升（比1/4茶杯略少）的橄榄油。研究人员对受试者尿样中的一种特殊成分进行检测，该成分是细胞氧化损伤产物的底物，也是癌症前体。在试验初期，北欧受试者该物质含量远远高于南欧受试者，但是，3周试验结束时，北欧受试者该物质含量明显降低。
"Determining the health benefits of any particular food is challenging because of it involves relatively large numbers of people over significant periods of time," said lead investigator Henrik E. Poulsen, M.D. of Rigshospitalet, Denmark. "In our study, we overcame these challenges by measuring how olive oil affected the oxidation of our genes, which is closely linked to development of disease. This approach allows us to determine if olive oil or any other food makes a difference. Our findings must be confirmed, but every piece of evidence so far points to olive oil being a healthy food. By the way, it also tastes great."
“确定任何一种特殊食品的保健作用都是一种挑战，因为这涉及相对众多人群以及有意义的食用时间。”首席研究员、来自丹麦Rigshospitalet的Henrik E. Poulsen博士说。“在我们的研究中，我们通过对观察橄榄油是如何影响与癌症发生有关基因的氧化作用，以克服这些挑战。该方法使得我们能够确定橄榄油或其他食品的不同作用。我们的发现还应得到证实，但是截止目前，每项证据都表明橄榄油是一种健康食物。顺便说的是，它的味道也非常棒。”
Another interesting finding in the study suggests that researchers are just beginning to unlock the mysteries of this ancient "health food." Specifically, the researchers found evidence that the phenols in olive oil are not the only compounds that reduced oxidative damage. Phenols are known antioxidant compounds that are present in a wide range of everyday foods, such as dark chocolate, red wine, tea, fruits, and vegetables. Despite reducing the level of phenols in the olive oil, the study's subjects still showed that they were receiving the same level of health benefits.
此项研究另外一项有趣的发现表明，研究人员仅刚刚揭开这一古老“健康食物”的神秘面纱。特别一提的是，研究人员发现酚类物质并非是橄榄油中能够降低氧化损伤的唯一成分。酚类物质被认为是存在于诸如黑巧克力、红酒、茶、水果以及蔬菜等众多日常食物中的抗氧化成分。尽管受试者减少橄榄油中酚类物质的摄入量，他们仍能同样受益于健康。
"Every New Year people make resolutions that involve eating less fat to improve their health," said Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal. "This academically sound, practically useful study shows that what you eat is just as important as how much you eat. No wonder Plato taught wisdom in an olive grove called Academe."
“每逢新年，人们都制定新年决心，包括少吃脂肪以促进健康，” FASEB杂志主编Gerald Weissmann说道，“这一学术上可靠、有指导意义的研究表明，吃什么与吃多少同样重要，无怪乎柏拉图在橄榄树林里教授的学者称为学院派。”
