 少しアルコール度の低いワインを毎日1杯飲むことで、いくつかのガンのリスクが下げられるという。
 World Cancer Research Fundによれば、研究成果をみると、14%よりも10%のアルコール濃度のワインを飲む方が効果的である。
 2007年に、アルコール消費とガンの関連が報告され、男性では1日に2杯以上、女性では1杯以上は飲まないように推奨していた。
 このデータを基に推計すると、1日1回250mlのワインを飲む場合に14%よりも10%の強度のワインにすると7%の腸ガンリスクが下げられるという。100人がそうすれば腸ガンの発症を1人減らせる。さらには、咽頭・食道・乳ガンなどのアルコールと関連するガンも減らせるだろう。

Weaker wine 'may lower the risk of some cancers'

Drinking a glass of wine at a lower strength could cut bowel cancer risk

Swapping a daily glass of wine for a slightly weaker alternative could be enough to lower the risk of some cancers, a charity suggests.

Studies suggest that people who drink wine with an alcohol content of 10% rather than 14% might benefit, says the World Cancer Research Fund.

The charity called for more low-alcohol wines and beers to be available for sale.

An industry expert said UK consumers were asking for "lighter" wines.

The calculation was based on figures in a 2007 report which looked at the evidence for a link between alcohol consumption and cancer.

That report recommended that men should have no more than two drinks a day, and women no more than one.

The figures used to reach that conclusion were detailed enough to reveal the likely extra risk posed by each extra 10 grams of alcohol - just over one unit - regularly consumed.

From this, scientists calculated that, in theory, a person drinking one large 250ml glass of wine a night would have a 7% lower risk of bowel cancer if they normally drank 10% strength wine rather than 14%.


From a cancer prevention point of view it is best not to drink at all. But we have to be realistic and the fact is that many people in the UK enjoy a drink and see it as part of their social life.

This is only a modest decrease of risk for an individual, and there is no clear evidence about how long someone would need to substitute weaker wine for their usual tipple in order to reap this benefit.

However, the charity said that for every 100 people who did it, one case of bowel cancer would be avoided.

While the detailed studies only applied to bowel cancer, it said that there was no reason to believe that the risk of other cancers linked to alcohol, such as throat, oesophageal and breast, would not respond in a similar way.

'Minor change'

Dr Rachel Thompson, science programme manager for WCRF, said: "From a cancer prevention point of view it is best not to drink at all.

"But we have to be realistic, and the fact is that many people in the UK enjoy a drink and see it as part of their social life.

"Making this change might seem quite minor to do, but it could have a real impact on cancer risk.

"If everyone who drinks 14% wine at the moment switched to lower-alcohol wine tomorrow, for example, it is likely hundreds of cancer cases in the UK a year could be prevented."

She said that while it was possible to find weaker alternatives, most wines still had a strength of 13% or 14%, and called on retailers to make more weaker wines available.

She said that beer drinkers could also expect similar benefits if they switched from premium strength to lower-alcohol brands.

More popular

Dr Peter Sasieni, a researcher in cancer prevention statistics from Queen Mary's University of London, said that while it was difficult to be precise about how a decision to change drinking lifestyle would affect individual cancer risk over the years, a move to lower-strength wines could offer protection.

He said: "Given that alcohol can be bad for you even in fairly low amounts, that would start to suggest that people should take note of the percentage of alcohol in their wine.

"If they are enjoying the 10% glass as much as the 14% one, it would make sense to opt for the 10%."

Gavin Partington, from industry body the Wine and Spirit Trade Association, said that the rise in the alcohol content of the wine sold in the UK was due to the increasingly popularity of southern hemisphere wines from countries such as Argentina, Chile and Australia, which, due to the climate, tended to have a higher content.

He said: "What we are noticing is that 'lighter' wines - such as Pinot Grigio - seem to be becoming far more popular, and these tend to have a lower alcohol content.

"This means that it is likely that more of these lower alcohol wines will be more available in the supermarket, simply as a product of changing consumer demand."

Press releases
Cancer charity urges switch to lower-alcohol wines

18 January 2010
People who drink a large glass of wine a day could reduce their risk of developing bowel cancer by seven per cent just by switching to a lower alcohol alternative, according to a cancer charity.

World Cancer Research Fund (WCRF) is urging drinkers to make the switch after calculating the impact of people who drink a large glass (250ml) of wine every day switching from a wine with an alcohol content of 14 per cent wine to a 10 per cent wine.

This reduction in risk could have a real impact on cancer in the UK. Roughly speaking, a seven per cent reduced risk of bowel cancer would mean that out of 100 people the number that would go on to develop bowel cancer would be reduced from six to five.

As well as reducing risk of bowel cancer, which affects about 37,000 people a year in the UK, there is also strong evidence that switching to a lower-alcohol wine would reduce risk of breast cancer, liver cancer, oesophageal cancer and cancers of the mouth, pharynx and larynx. The reduction in risk for each type of these cancers is thought to be similar to that for bowel cancer.

Overall, scientists estimate about 20,000 cases of cancer are diagnosed every year that are linked to alcohol. This is why WCRF recommends that if people drink at all, they limit consumption to two drinks a day for a man and one for a woman.

Dr Rachel Thompson, Science Programme Manager for WCRF, said: “From a cancer prevention point of view it is best not to drink at all. But we have to be realistic and the fact is that many people in the UK enjoy a drink and see it as part of their social life.

“If you drink quite a lot at the moment, the best advice is to reduce the number of drinks you have. But if people do not want to do this, switching to a lower alcohol alternative is still something positive they can do. Making this change might seem quite minor do, but it could have a real impact on cancer risk. If everyone who drinks 14 per cent wine at the moment switched to lower-alcohol wine tomorrow, for example, it is likely hundreds of cancer cases in the UK a year could be prevented.

“It is true that most wines in the supermarket these days tend to be 13 or 14 per cent, which means finding lower-alcohol alternatives can be difficult. But it is worth the effort because switching to a lower-alcohol alternative is the kind of lifestyle change that can make a real difference because it is easy to stick to in the long term.

“Of course, this does not just apply to wines. You can also reduce your cancer risk by switching from premium strength lager to weaker alternatives and this also applies to any alcoholic drink.”

“Also, it will hopefully become easier to find lower-alcohol drinks because the food and drink industry does now seem to taking the issue more seriously. But there is still much more it should be doing. We would like to see supermarkets and off-licenses make it easier for their customers to choose less unhealthy options.”
