　　研究人员由此得出结论：肉类长期食用史对评估癌症危险很有价值，这也证明，长期大量食用红肉和肉制品会增加大肠远端癌症危险。

　　Long-term high consumption of red and processed meat may increase the risk of cancer in the colon and rectum, according to research.

　　US researchers followed a cohort of 148,610 adults, with an average age of 63 years from 1982.

　　Participants completed questionnaires at 10-yearly intervals regarding their diet, exercise, medical history and other lifestyle habits.

　　By 2001, there were 1667 new cases of colorectal cancer in the group, according to the report published in the Journal of the American Medical Association.

　　Prolonged high consumption of poultry and fish was marginally associated with about a 25 percent lower risk of colon cancer, but not rectal cancer.

　　The researchers conclude that: 'Our results demonstrate the potential value of examining long-term meat consumption in assessing cancer risk and strengthen the evidence that prolonged high consumption of red and processed meat may increase the risk of cancer in the distal portion of the large intestine.'
