Women who had an average 2.3 drinks or more per week had a 72% greater risk of having psoriasis than women who didn't drink. But when various types of alcohol were assessed, there was a higher risk for the disease among women who drank regular beer. Drinking light beer, red or white wine, or liquor were not linked with a risk of psoriasis. Women who drank at least five regular beers a week were 1.8 times more apt to contract psoriasis than women who did not drinkPsoriasis causes "cells to build up rapidly on the surface of the skin, forming thick silvery scales and itchy, dry, red patches that are sometimes painful."
I guess it should be pointed out that only 2.2% of the population has psoriasis, so even the consumption of beer isn't going to cause many women to develop it--proportionately, anyway. Still, not the greatest news ever.
