When my psoriasis is not flaring, it does not bother me very much, and I don’t think about it. But when a flare starts, it bothers me a lot. If I decide to follow a gluten-free diet, should I do it all the time or only during flares?
Although the evidence suggests that a gluten-free diet may be useful for certain people with psoriasis, many studies are not totally conclusive. For this reason, it is not exactly clear if or when following the diet would be helpful.
If a person finds that a gluten-free diet helps their psoriasis and prevents flares, they may wish to pursue the diet even when they are not flaring. Remember that a gluten-free diet is not meant as a replacement to conventional therapies for psoriasis. A person should discuss the risks and benefits of this diet beforehand with their doctor and a dermatologist.
