【健康常识】红葡萄酒的四大好处 [复制链接]

http://www.redwinelife.com/new/viewnews.asp?id=9849

从医学的最新研究结果看，经常饮用红葡萄酒，起码有四大好处。

  第一是延缓衰老

  人体跟金属一样，在大自然中会逐渐“氧化”。金属氧化是铁生黄锈，铜生铜绿，人体氧化的罪魁祸首不是氧气，而是氧自由基，是一种细胞核外含不成对电子的活性基因。这种不成对的电子很易引起化学反应，损害DNA（脱氧核糖核酸）、蛋白质和脂质等重要生物分子，进而影响细胞膜转运过程，使各组织、器官的功能受损，促进机体老化。

  红葡萄酒中含有较多的抗氧化剂，如酚化物、鞣酸、黄酮类物质、维生素C、维生素E、微量元素硒、锌、锰等，能消除或对抗氧自由基，所以具有抗老防病的作用。

  葡萄酒中维生素B12的含量是其它食物无法比拟的，同时它也是人体内造血功能的必需物质，不仅如此，葡萄酒还含有丰富的铁质，这为缺铁性贫血病人提供了最好的补品。因此葡萄酒具有补血之功效。

  据调查统计表明，生活在盛产葡萄酒区域的人们，由于饮用葡萄酒的机会较多，所以平均寿命较长。在葡萄种植园工作的农民，平均寿命达90岁以上。

  第二是预防心脑血管病

  红葡萄酒能使血中的高密度脂蛋白（HDL）升高，而HDL的作用是将胆固醇从肝外组织转运到肝脏进行代谢，所以能有效的降低血胆固醇，防治动脉粥样硬化。

  不仅如此，红葡萄酒中的多酚物质，还能抑制血小板的凝集，防止血栓形成。虽然白酒也有抗血小板凝集作用，但几个小时之后会出现“反跳”，使血小板凝集比饮酒前更加亢进，而红葡萄酒则无此反跳现象。在饮用18个小时之后仍能持续的抑制血小板凝集。

  第三是预防癌症

  葡萄皮中含有的白藜芦醇，抗癌性能在数百种人类常食的植物中最好。可以防止正常细胞癌变，并能抑制癌细胞的扩散。

  将白藜芦醇加到人工培养的人类白血病细胞中，结果发现这些血癌细胞丧失了复制能力。科学家已经从葡萄、桑树、花生等70多种植物中发现了白藜芦醇，其中以葡萄制品含量最高。

  在各种葡萄酒中，又以红葡萄酒的含量最高。因为红葡萄酒是用果皮、果肉果仁、果梗共同酿制的，而有些葡萄酒则仅用果肉酿制，所以红葡萄酒是预防癌症的佳品。

  第四是美容养颜

  自古以来，红葡萄酒作为美容养颜的佳品，倍受人们喜爱。有人说，法国女子皮肤细腻、润泽而富于弹性，与经常饮用红葡萄酒有关。

  红葡萄酒能防衰抗老，这就包括延缓皮肤的衰老，使皮肤少生皱纹。除饮用外，还有不少人喜欢将红葡萄酒外搽于面部及体表，因为低浓度的果酸有抗皱洁肤的作用。

  红酒还具有缓解痛经的作用，按中医理论，葡萄酒味辛甘，性温，对寒湿凝滞的痛经可以起散寒祛湿，活血通经补暖的作用，起到温阳补血缓解止痛的效果。

  据记载，过去的法国宫廷贵妇人，如今的影视明星和服装模特，常将陈年红葡萄酒外用，以此来保养皮肤，使皮肤更加光泽、细腻，富有弹性。

CDEP: A Half Glass of Wine Daily May Add Years to Life

ORLANDO, Fla., March 1 -- Men who limited alcohol intake to less than a glass of wine a day lived about four years longer than those who consumed similar amounts of beer or spirits, researchers here reported.

A number of studies have linked alcohol consumption-especially red wine consumption-to decreased risk of cardiovascular events, but Martinette T. Streppel, a Ph.D., student at Wageningen University in Bilhoven, The Netherlands, said this study may be the first to suggest that wine itself confers a survival benefit. Action Points

Explain to interested patients that this report was derived from an observational study and the findings need to be confirmed in a prospective study.

This study was published as an abstract and presented orally at a conference. These data and conclusions should be considered to be preliminary as they have not yet been reviewed and published in a peer-reviewed publication.
Compared with non-drinkers, men who consumed wine, beer, or spirits had a 36% lower risk of all-cause mortality and a 34% lower risk of cardiovascular mortality, she said at the Conference on Cardiovascular Disease Epidemiology and Prevention, which is sponsored by the American Heart Association.

"But men who drank about a half a glass of wine a day had a 40% reduction in all cause mortality and a 48% lower incidence of cardiovascular death," said Daan Kromhout, Ph.D., a professor of public health at Wageningen University and vice president of the Health Council of The Netherlands. Dr. Kromhout was senior author of the paper.

The finding emerged from analysis of data collected in the Zutphen Study, a cohort study of 1,373 men born between 1900 and 1920, which Streppel and colleagues reported. The men were enrolled in the study at age 40 and were followed for an average of 40 years.

Information about alcohol consumption as well as dietary habits, smoking, body mass index, and prevalence of heart disease, stroke, diabetes, and cancer, was collected by seven surveys conducted over the course of the study.

Light alcohol intake was defined as 20 grams or less a day, or about two glasses of wine. The average long-term intake was six grams of alcohol daily, which was equal to four ounces of beer, two ounces of wine, or one ounce of spirits.

Compared with men who did not consume alcoholic beverages, wine drinkers lived 3.8 years longer.

Among the findings:

45% of the men used alcohol in 1960, when they were 40 to 60 years old, but 85% of the men who survived until the year 2000 used alcohol.
In 1960, the average consumption was eight grams of alcohol daily, which increased to 18 grams a day in 1985 and decreased to 13 grams.
In 1960, 2% of the men were wine drinkers versus more than 40% of the men in the final survey in 2000.

The study did not differentiate between type of wine consumed, said Dr. Kromhout, who added "the type of wine consumed-red or white-usually varies by the season with red wine being more popular during the winter months."

Streppel speculated that the benefit observed for light wine drinkers might be linked to an increase in HDL cholesterol-a finding that has already been reported in other wine studies-or to "inhibition of platelet aggregation associated with wine."

The study was funded by the The Netherlands Food and Consumer Product Safety Authority and The Netherlands National Institute for Public Health and the Environment.

Drinking a little wine linked to men's longer life

Wed Feb 28, 6:25 PM ET

WASHINGTON (Reuters) - Drinking a small amount of wine appears to extend men's life expectancy by a few years, Dutch researchers said on Wednesday in the latest study to find benefits in moderate drinking.

Dutch researchers sought to gauge the impact on health and life expectancy of long-term alcohol consumption, tracking 1,373 men born between 1900 and 1920 who lived in Zutphen, an industrial town in the Netherlands.

The researchers followed alcohol intake in seven surveys carried out over four decades starting in 1960, tracking some men until they died and the rest until 2000. The men were asked about drinking, eating and smoking habits, weight, and prevalence of heart attack, stroke, diabetes and cancer.

Drinking a small amount of alcohol -- less than a glass per day -- was associated with lower rates of death from cardiovascular causes and overall causes, the study found.

Drinking wine appeared to be more protective than spirits and beer. Drinking an average of about half a glass of wine per day was associated with lowest mortality levels, it found.

Unlike other studies on health effects of alcohol consumption, this one sought to measure any extension in life expectancy, the researchers said.

The study found that men who drank wine had a life expectancy 3.8 years longer than those who drank no alcohol. These wine drinkers also had a life expectancy two years longer than those who drank other alcoholic beverages, it found.

The study was not designed to look at the well-documented health risks of heavy alcohol consumption.

"The main message is that if you already consume alcoholic beverages, do so moderately -- one or two glasses per day maximum," Martinette Streppel, lead author of the study, said in a telephone interview.

"And if you have to choose a certain beverage, then at least drink wine, because it has an additional beneficial effect above just the effect of alcohol itself," added Streppel, of Wageningen University and the National Institute for Public Health and the Environment in the Netherlands.

The researchers found men's long-term consumption of up to two glasses of alcohol a day was associated with about a one-third lower overall mortality risk and risk of cardiovascular death compared to men who drank no alcohol.

The study did not look at how alcohol may provide health benefits, but Streppel said it could be due to an increase in high-density lipoprotein (HDL) cholesterol, or to a reduction in blood clotting. Also, red wine has compounds that may ward off the build-up of fatty tissue in the arteries that can cause a stroke or heart attack.

The findings were presented at an American Heart Association conference in Orlando, Florida.
