Foods To Avoid For Psoriasis

Psoriasis is a condition characterized by raised, pink patches of skin that are covered with silvery scales, according to Dr. James F. Balch, author of "Prescription for Nutritional Healing." White blood cells, called T cells, attack healthy skin cells, causing them to shift to the skin's outer layers too quickly. Although the cause of psoriasis is unknown, it is thought to be triggered by several factors, including heavy tobacco and alcohol use, obesity, emotional stress and streptococcal infections. Certain foods also might trigger psoriasis outbreaks, according to the University of Maryland Medical Center.

Nutritional changes should not replace conventional medical treatment. Talk to your doctor if you plan to change your diet to help control psoriasis.

Wheat Gluten

Wheat gluten is a water-insoluble protein left over after the starch has been washed away during wheat flour processing. It is used to make seitan, a meat replacement for vegetarians and vegans. It is also an ingredient in breads, pastas and pastries. Wheat gluten might trigger an allergic reaction that can cause T cells to attack skin cells and produce psoriasis outbreaks, according to the University of Maryland Medical Center. Avoiding products that contain wheat gluten might help control psoriasis.

Saturated Fats

These might trigger psoriasis outbreaks and extend the time necessary to heal painful skin patches, according to Balch. Some medical researchers believe that this is because saturated fats can clog arteries, impairing blood flow and reducing the levels of nutrients available to skin tissues. People with psoriasis should limit or avoid foods that contain saturated fats, including red meat, pork, milk, cheese and yogurt.

Simple Carbohydrates

White breads, pastas, doughnuts, fast foods and many packaged snack foods such as crackers and cakes contain white flour and sugar, both of which are simple carbohydrates. These carbohydrates are quickly converted by the body into glucose, which can trigger psoriasis outbreaks, according to Balch. Whole-grain breads and pastas that do not contain wheat gluten make excellent replacements for simple carbohydrate-laden foods.
