Ohio State study shows which healthy habits can prevent or improve psoriasis


COLUMBUS, Ohio (WEHT) – More than 8 million Americans suffer from psoriasis, and a new study from The Ohio State University Wexner Medical Center is giving insight into lifestyle choices that may prevent or improve psoriasis.

“Psoriasis is an autoimmune disease, so although it often presents as red, scaly patches on the skin, we know that the causes are more than skin deep,” said Dr. Benjamin Kaffenberger, a dermatologist at The Ohio State University Wexner Medical Center who led the study. “So we’re looking for some sort of trigger that sets off the immune system. And because strep throat is one of those triggers and there are millions of microbiome bacteria in the mouth, that is a good place to start.”

Researchers asked patients about their health habits.

Those with poor gum health or with oral pain were found to be more likely to have severe psoriasis symptoms.

According to the study, habits like losing weight, avoiding alcohol and cigarettes, and eating plenty of fruit were associated with less severe symptoms.
