Increased psoriasis risk for women who drink beer

Tuesday 17th August, 2010

Women who are regular beer drinkers are more likely to develop psoriasis, according to a new US study.

Results from the study found that drinking just five beers a week doubled the risk of developing the skin condition compared to women who didn’t drink.

The drinking habits of over 82,000 female nurses aged 27-44 between the years 1991 and 2005 were studied. Researchers observed a 72 per cent increased risk of psoriasis in women who consumed more than 2.3 drinks per week. For those who drank five beers per week the risk was nearly double again.

In the study, which was published in Archives of Dermatology journal, author Dr Abrar Qureshi wrote:

‘Non-light beer was the only alcoholic beverage that increased the risk of psoriasis, suggesting that certain non-alcoholic components of beer, which are not found in wine or liquor, may play an important role in new-onset psoriasis.’

Researchers believe the risk comes as a result of gluten-containing barley which is used in the fermentation process of beer. This is consistent with previous studies which have shown psoriasis may be improved by eating a gluten-free diet.
