為健康飲酒?（通訊員稿）

我們常說飲酒有害身體健康，然而根據(jù)最新的醫(yī)學(xué)研究發(fā)現(xiàn)，每天適量飲酒可能會使患阿爾茨海默氏(早老性癡呆)或其它類型癡呆癥的危險減少一半，這又該作如何解釋呢？
 Daily, moderate drinking could almost halve the
risk of developing Alzheimer's disease or other types of dementia, according to
new research.
The finding adds to a growing body of evidence for the health benefits of
moderate drinking, which is already known to protect against heart disease and
stroke.
The study, published this week in The Lancet medical journal, also found that
it doesn't seem to matter what people drink - the effect is the same.
Experts say moderation - between one and three drinks a day - is the key.
The adverse effect of excess alcohol is beyond question.
Researchers suggested the blood-thinning and cholesterol-lowering properties
of ethanol in alcohol may ward off dementia, which is often caused by a blood
vessel problem.
Another possibility, the study speculated, is that low levels of alcohol
could stimulate the release acetylcholine, a brain chemical believed to
facilitate learning and memory.
