Does wheat cause psoriasis?
Bread is a popular source of carbohydrates in many countries around the world. Although it may take on different shapes, forms, and flavors, the main ingredients of bread are typically the same: flour, water, milk, eggs, yeast, and sugar. The flour used in bread is usually derived from wheat, and contains high amounts of the protein gluten. Gluten is the component found in flour that allows the bread to be kneadable. However, some people are allergic to gluten and are required to avoid bread, cereals, and other gluten-containing products. There are gluten-free flours and breads available on the market that allow people to enjoy many baked goods, pastas, and sauces without the risk of triggering an allergic reaction to the gluten. The eggs that are contained in some bread, may also be a source of pro-inflammatory substances such as arachidonic acid and certain proteins that may trigger an allergic reaction in some individuals.
For people with psoriasis, it is recommended to avoid or limit the amount of bread ingested. Studies show that in people with both psoriasis and a gluten allergy, their psoriatic symptoms are relieved when consumption of gluten is stopped. It is best for a person with psoriasis and pre-existing allergies, to avoid the allergens to prevent any allergic reaction which may also trigger a flare up. Although there seems to be an improvement of symptoms of psoriasis when gluten and other allergens are avoided, there is no direct connection with providing a cause or cure for psoriasis itself.
