A new study seems to show that non-light beer may boost risk of psoriasis in women. But yet others say that it is vitamin D deficiency that could be the culprit, beer having only an incidental role to play.
Psoriasis is a chronic, autoimmune disease that occurs on the skin when the immune system send out wrong signals that speed up the growth of skin cells.
The study led by Abrar A. Qureshi, M.D., M.P.H., of Brigham and Women's Hospital and Harvard Medical School, Boston found women who drank five or more non-light beers per week were 2.3 times as likely as those who did not drink beer to be diagnosed with psoriasis.
The authors of the study said in their report that alcoholic beverages have been suspected for a long time as a risk factor for psoriasis onset and psoriasis worsening. Alcohol drinkers are known to be more likely to suffer the disease and alcohol may exacerbate the severity of the disease.
For the study, the researchers surveyed 82,860 women aged 27 to 44 who participated in the NUrses' Health Study II for the amount and type pf alcohol they consumed through biennial questionnaires and participants reported also whether they were diagnosed with psoriasis.
Women who had an average of 2.3 drinks or more each week were 72 percent more likely than those who did not drink alcohol to report they suffered psoriasis, the study found.
