The researchers, led by the Basque Public Health Department, placed the participants into six categories – from never having drunk to drinking more than 90g of alcohol each day. This would be the equivalent of consuming about eight bottles of wine a week, or 28 pints of lager.

For those drinking little – less than a shot of vodka a day for instance – the risk was reduced by 35%. And for those who drank anything from three shots to more than 11 shots each day, the risk worked out an average of 50% less.
