According to Lawrence E. Gibson, M.D. from Mayo Clinic, “although there’s no special psoriasis diet, some people find that certain foods worsen their symptoms or that others improve skin inflammation.”
It can be difficult to determine what exactly is changing your psoriasis symptoms because the condition itself tends to fluctuate over time — with periods of remission alternating with times when your psoriasis becomes worse.
Gibson adds: “Studies have found that some people who have psoriasis may also be sensitive to gluten — a protein found in wheat, barley and rye. In these people, avoiding gluten may ease their psoriasis symptoms.”
If you are concerned about gluten sensitivity, ask your doctor about tests you can take to either confirm or rule out this condition.
