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 settle the question and is the first to find blacks and Hispanics benefit as well as whites, according to the authors. Further research is needed among other groups, such as Asian, whom past study suggested may get no stroke protection from alcohol or may even be put at greater risk.
Among the groups where the protective effect exists, its mechanism appears to differ from the protective effect against heart attacks, which occurs through boosts in levels of so-called "good’ cholesterol, the authors said. They speculated alcohol might protect against stroke by acting on some other blood trait, such as the tendency of blood platelets to clump, which is key in forming the blood clots that can cause strokes①.
The researchers studied 677 New York residents who lived in the northern part of Manhattan and had strokes between July 1, 1993 and June, 1997. After taking into account differences in other factors that could affect stroke risk, such as high blood pressure, the researchers estimated that subjects who consumed up to two alcoholic drinks daily were only half as likely to have suffered clot-type strokes as nondrinkers②. Clot type strokes account for 80 percent of all strokes, a leading cause of the US deaths and disability. Stroke risk increased with heavier drinking. At seven drinks per day, risk was almost triple that of moderate drinkers.
An expert spokesman for the American Heart Association, who was not involved in the study, said it was well-done and important information. But it shouldn’t be interpreted to mean, "I can have two drinks and therefore not worry about my high blood pressure or worry about my cholesterol," said Dr. Edgar J. Kenton, an associate professor of clinical neurology at Thomas Jefferson University Medical College in Philadelphia. Instead, he said, the study provides good reason to do further research and to add alcohol to the list of modifiable risk factors for stroke. [br] From the fourth paragraph we learn that ______
选项
A、heart attacks are more likely caused by alcohol than stroke
B、moderate drinking discourages blood platelets from clotting
C、boosting the levels of good cholesterol can lead to heart attacks
D、moderate drinking protects people by making the blood cell clump
答案
D
解析
推理判断题。选项A 与文章意思不符,尹以排除。根据文章第四段最后一句:酒防止中风的方式也许是通过作用于血液的其他特性——如血小板凝固来实现的,而这正是造成中风的关键,所以选择B “适量饮酒可防止血小板凝固”,而选项D 意思正好相反,所以排除。
