In their prospective study in a recent issue of the Archives, Qureshi et al1 provide convincing evidence that intake of nonlight beer increases the risk of developing psoriasis. Since there are several other factors known to negatively influence psoriasis, such as obesity and smoking,2 it seems reasonable to counsel patients on lifestyle modification, as proposed by Shelling and Kirshner3 in a “Practice Gaps ” article in the same issue of the Archives. However, the effectiveness of such counseling is somewhat questionable because of personality traits rendering patients with psoriasis susceptible to addictive behavior concerning alcohol and food intake.4
