A new study finds that women who drink beer regularly have a higher risk of psoriasis by over 70 percent. Therefore women who are susceptible to the skin syndrome psoriasis should decide to reduce their intake of beer and also switch to light beer.

Psoriasis is an auto-immune skin disease which causes scaly lesions, redness and inflammation of the skin. The National Psoriasis Foundation says that 2.5 percent of Caucasians and 1.3 percent of African-Americans suffer from this skin disease.

The exact cause of the disease is till not known but doctors believe that something triggers the immune system, which in turn sets off a chain reaction that causes skin cells to reproduce too quickly.

Dr. Abrar A. Qureshi of Brigham and Women's Hospital and Harvard Medical School assessed years of follow-up data from 82,869 women who participated in a 1991 study done to analyze the link between various types of alcohol and psoriasis.

By the year 2005 the women reported 1,150 diagnoses. After analyzing the statistics the researchers found that women who reported averaging at least 2.3 drinks per week had a 72 percent higher chance of psoriasis than women who do not drink.
