[单项选择]　Study Confirms Red Meat Link with Bowed （结肠） Cancer 　　People who eat more than 160 grams of red or processed meat a day are 35 percent more likely to develop bowel cancer than those who ear less（51） 20 grams a day， according to one of the biggest nutrition investigations ever carried out. 　　The European Prospective Investigation into Cancer and Nutrition followed 478，040 men and women （52）35 to 70 from 10 European countries. 　　All subjects were free of cancer at enrollment between 1992 and 1998， but （53） an average follow-up of almost 5 years 1，329 bowel cancers had been reported. 　　The subsequent analysis， published in the Journal of the National Cancer Institute， confirms the long-held suspicion （54） high intakes（纳入量） of red meat are associated with increased bowel（55） risk. After taking into consideration factors like age, sex, height, weight, energy intake physical activity, smoking, and alcohol consumption, the investigators found that bowel cancer was (56) with intake of re

[单项选择]Study confirms that moderate drinking reduces stroke risk. Similar to the way a drink or two a day protects against heart attacks, moderate alcohol consumption wards off strokes, a new study found.
The study also found that the type of alcohol consumed—beer, wine or liquor-was unimportant. Any of them, or a combination was protective, researchers reported in today’s Journal of the American Medical Association. "No study has shown benefit in recommending alcohol to those who do not drink", cautioned the authors, led by Dr. Ralph L. Sacco of Columbia University College of Physicians and Surgeons in New York. But the new data support the guidelines of the National Stroke Association, which say moderate drinkers may protect themselves from strokes by continuing to consume alcohol, the authors said.
The protective effect of moderate drinking against heart attacks is well established, but the data had been conflicting about alcohol and strokes, the authors said. The new study helps
A. different wines work differently on drinkers at stroke risk
B. nondrinkers should also consume a moderate amount of alcohol
C. drinkers should keep to one kind of alcohol to ward off strokes
D. moderate alcohol consumption protects against strokes
