Ask the Doctors: Healthy diet can restrict psoriasis flare-ups

Dear Doctor: I’ve had psoriasis for close to seven years, and lately it has been flaring up more often. Is there anything I can do with my diet to control this, or even prevent it from happening?

Dear Reader: That’s a good question. Thanks to the growing body of research detailing the link between inflammation and chronic disease, there are some equally intriguing answers. To explore it further, let’s start with what psoriasis is.

When you have psoriasis, your immune system has gone a bit haywire. It’s sending faulty danger signals that cause skin cells to grow at 10 times their normal rate. That’s much faster than your body can process and shed them, and the result is raised and itchy patches of red skin, often covered with silvery scales. Typically, these appear on the knees, elbows and scalp, but may also be present on the palms of the hands, soles of the feet and along the torso.
