No Link Between Coffee and Psoriasis

Studies have linked drinking beer and smoking cigarettes to developing the skin ailment psoriasis.  Not so with coffee!  Researchers at Brigham and Women’s Hospital in Boston looked at more than 82,000 participants over 14 years to determine there is no link between drinking coffee and developing psoriasis.

Initially it did appear caffeine might have played a role in the development of psoriasis; however, those who drank more coffee typically also drank more alcohol and smoked cigarettes. Over time it became apparent the link was to the alcohol and smoking, not coffee.

Psoriasis is caused by an abnormal immune system attack on one’s own body, causing red, scaly patches on the skin.  A group of Irani researchers also applied caffeine directly to the skin of volunteers with psoriasis and found an apparent benefit; however, that wasn’t investigated in this study.
