New evidence indicates that a daily touch of the grape can have astounding health benefits.Salud（注：salud祝您健康；干杯）!
"DRINK A GLASS of wine after your soup,"an old Russian proverb says,"and you steal a ruble（注：ruble卢布（苏联货币）） from the doctor." It's a sentiment（注：sentiment意见；感情；感想） that nutrition re searchers now toast with a raised glass.
You've probably heard that drinking a glass or two of wine a day can lower your risk of dying from heart disease-by 30 to 40 percent,according to Harvard University scientist Walter Willett,author of Eat,Drink and Be Healthy and one of the country's leading nutrition experts.But wine's benefits go further:Howard University Hospital researchers reported last year that moderate wine drinkers are less likely to develop macular（注：macula=yellow spot（视网膜的）黄斑；macular有黄斑的）degeneration,an age-related eye condition that can lead to partial blindness.Other recent studies suggest postmenopausal women who consume moderate amounts of alcohol every day-the equivalent of one to two glasses of wine-have stronger bones than non-drinkers.Wine may also lower the risk of diabetes and gallstones.
How does wine bestow（注：bestow赠与；给予） its remarkable bene fits? In the case of heart disease,research shows that alcohol opens up arteries and increases blood flow.That's important,since a heart attack usually occurs when a blood clot（注：blood clot血块） robs heart muscles of oxygen.Moderate drinking also increases levels of HDL（注：HDL high density lipoprotein高密度脂蛋白） cholesterol-so-called good cholesterol- which helps the body get rid of LDL（注：LDL low density lipoprotein低密度脂蛋白）cholesterol,the artery-clogging form.The antioxidants（注：antioxidant抗氧（化）剂；防老（化）剂） abundant in some forms of alcohol,especially red wine,can prevent LDL cholesterol from oxidizing; this damages artery walls,setting the stage（注：set the stage for为……创造条件，使成为可能）for heart disease.
Despite these glad tidings,many public health experts are reluctant to recommend a glass or two of wine.The reason? "For one thing,too much of a good thing can be dangerous," says Willett.Forty percent of all traffic accidents are alcohol-related.Alcoholism（注：alcoholism酗酒；酒精中毒） can also be deadly.
"If you don't drink,don't feel compelled（注：compel强迫；使不得不）to start," says Willett."There are plenty of ways to get many of the same benefits." Exercise and a better diet top the list.
If you already drink,remember another piece of age-old wisdom:moderation in all things.Beyond two or three drinks a day,the risks begin outweighing the benefits.
新的证据表明每日少量葡萄酒对健康的益处令人惊讶。为您的健康，干杯！
有一句古老的俄罗斯谚语说，“汤后一杯葡萄酒，等于偷走医生一卢布。”这也是营养学家们举杯祝酒时的祝愿。
你可能听说过，根据哈佛大学科学家瓦尔特·威莱特的说法，每天一至两杯葡萄酒可以使死于心脏病的风险降低30%至40%。威莱特是美国最杰出的营养学家之一，《饮食与健康》一书的作者。但是葡萄酒的益处还不限于此：哈佛大学附属医院研究人员在去年的报告中指出，适度饮用葡萄酒者较少发生视网膜黄斑性退化，这是一种随年龄增长而产生的可能导致部分失明的眼疾。最近还有其他的研究表明绝经妇女每日适量饮相当于一至两杯葡萄酒的酒精，其骨质比不饮酒者强壮。葡萄酒还能降低患糖尿病和胆结石的风险。
为什么葡萄酒会带来如此大的益处呢？就拿心脏病来说吧，研究表明酒精能使动脉舒张增加血流量。这非常重要，因为突发心脏病多是因血液凝块使心肌缺氧所致。适量饮酒同时还会增加高密度胆固醇的含量，人们将这种胆固醇称为好的胆固醇，因为它有助于排除造成动脉血管堵塞的低密度胆固醇。在有些酒类里，特别是红葡萄酒里含有丰富的抗氧剂，它可防止低密度胆固醇氧化，这种氧化会对动脉血管壁造成伤害，成为心脏病的隐患。
虽然这些消息令人鼓舞，但许多公共卫生问题专家却并不愿提倡每日一至两杯酒。原因何在？“首先，好东西太多也有危险，”威莱特说。40%的交通事故都与饮酒有关，而酗酒更有致命的危险。
“如果你不饮酒，千万别勉强为之，”威莱特说，“有很多其他途径可以取得同样好的效果”。加强锻炼和合理饮食始终应为强身健体的首选之道。
如果你本来就饮酒，那么也请记住另一句古老的智慧名言：凡事皆有度。一天饮酒超过两三杯，害处就会大于益处。
