过食加工肉类增加癌症风险_报刊文摘
los angeles (reuters) - a diet containing lots of processed meats, like hot dogs and sausages, raises the risk of pancreatic cancer, according to a large multiethnic study unveiled on wednesday.
the researchers found that heavy consumers of processed meats -- 40 grams a day or more -- were 67 percent more likely to develop cancer of the pancreas than study participants with the lowest intake.
in addition, a diet rich in pork and red meat -- 70 grams a day or more -- also increased pancreatic cancer risk by about 50 percent, according to the survey-based study.
but the american meat institute disputed the findings, pointing out that a study published earlier this week in the journal of the national cancer institute reached an opposite conclusion.
"the most important fact is that the larger body of evidence has shown that processed meats are a healthy part of a balanced diet," the trade group said in a statement.
dr. ute nothlings, the study’s lead investigator from the cancer research center at the university of hawaii in honolulu, said "the results suggest that carcinogenic substances related to meat preparation, rather than their inherent fat or cholesterol content, might be responsible ...."
she suggested that chemical reactions that occur during the preparation of processed meats might be responsible for the association.
she noted, however, that the study did not examine cooking methods and her team is now working to collect that data.
the results were reported a meeting of the american association for cancer research in anaheim, california.

本周三，一项跨多种族的大型调查研究指出，含有大量加工肉类的饮食，如热狗和香肠，会增加患胰腺癌的风险。
研究者发现，食用大量加工肉类（每天40克或更多）的消费者患胰腺癌的几率比加工肉类摄入量最低的受测验人员要高67个百分点。此外，富含猪肉和红色肉类的饮食（每天70克或更多）也将患胰腺癌的风险提高了约50个百分点。
但美国肉类协会就这一说法提出了异议。该协会指出，本周《美国国家癌症研究所杂志》发表的一篇研究报告得出了截然不同的结论。该贸易协会在一篇报告中说，“一个重要的事实是，大量证据表明加工肉类是均衡饮食的一个卫生健康的组成部分。”
该项研究的领导研究员员、来自夏威夷大学癌症研究中心的ute nothlings博士说，“研究结果表明，致癌物质与肉类调制品有关，而与其含有的脂肪和胆固醇成分无关……” 她提出，可能在加工肉类的调制过程中所发生的某些反应应对这种加工肉类与胰腺癌之间的关联负责。
但她强调，该研究未考虑烹饪方法的因素，现正在搜集此方面的数据。
该研究结果是在位于加利福尼亚州阿拉罕的美国癌症研究协会的一次会议上发布的。
