A charity suggests swapping a daily glass of wine for a slightly weaker alternative could be enough to lower the risk of some cancers. The World Cancer Research Fund says studies suggest that people who drink wine with an alcohol content of 10 per cen rather than 14 per cent might benefit. <br/><br/>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. <br/><br/>From this, scientists calculated that, in theory, a person drinking one large 250ml glass of wine a night would have a 7 per cent lower risk of bowel cancer if they normally drank 10 per cent strength wine rather than 14 per cent. The charity called for more low-alcohol wines and beers to be available for sale.
