GLUTEN FREE DIET

Supermarkets have recently seen an explosion of gluten-free foods. Gluten is a protein in wheat and some grains (like rye and barley). It is also found naturally in a wide variety of foods from bread to beer to soy sauce.

There is early evidence of an increased risk of celiac disease (intolerance to eating gluten) in patients with psoriasis. In those patients who do have both conditions, a gluten-free diet has been shown to help improve their skin.


If you have other symptoms of gluten intolerance, like diarrhea, gas, persistent fatigue, or low iron and anemia, discuss these with your doctor. Blood and other tests are available to check for celiac disease. A gluten-free diet can take some getting used to, and you have to be careful because many prepared or restaurant foods can have hidden sources of gluten. Usually three months of following the diet strictly should be enough to see if it will help your psoriasis.
