If you have psoriasis, an important part of keeping your condition under control is working with your doctor to develop a treatment plan that’s right for you. And you may be wondering if there’s anything else you can do to help manage your disease—such as altering your diet.

There’s lots of talk about eating habits and how they may or may not affect psoriasis, and the truth is, there’s no one-size-fits-all food plan that’s going to clear up everyone’s symptoms.

“We have no good studies that prove whether one particular diet can affect psoriasis,” explains Laura Ferris, M.D., Ph.D., associate professor of dermatology at the University of Pittsburgh.
