Psoriasis is a chronic skin disease characterized by patches of skin that are itchy, red and covered with thick white scales. Scientists believe that a genetic susceptibility and chronic inflammation are the cause of the disease. For some psoriasis patients, symptoms can improve with dietary changes. Nutrients that suppress inflammation may improve symptoms, according to the article "Diet and Psoriasis: Experimental Data and Clinical Evidence" published in 2005 in "British Journal of Dermatology." Before making any dietary changes, consult with your doctor.
Gluten-Free
Some psoriasis patients have a sensitivity to gluten as evidenced by antigliadin antibodies. For these patients, symptoms improved after three months on a gluten-free diet. Eating cereals containing the protein gluten may cause small bowl inflammation in these psoriasis individuals. The cereals that should be avoided on a gluten-free diet include rye, oats, barley, wheat, semolina, bulgur, durham, farina, triticale, spelt and kamut. The Mayo Clinic recommends avoidance of a number of other foods unless the label says gluten-free. These foods include beers, cakes, pies, breads, cookies, crackers, pasta, soy sauce, soups, salad dressing, imitation meat and seafood. If you would like to try a gluten-free diet for your psoriasis, consult with your doctor.
Restrict Alcohol
The article "Diet and Psoriasis" notes that psoriasis patients are often alcohol drinkers as well. Alcohol stimulates the release of histamine, which in turn can worsen psoriasis skin plaques. It is recommended that you restrict your consumption of alcohol if you have psoriasis.
Avoid Arachidonic Acid
Arachidonic acid is a polyunsaturated essential fatty acid and one of the omega-6 oils. While omega-3 oils tend to reduce inflammation, some omega-6 oils, like arachidonic acid, promote inflammation. The "British Journal of Dermatology" study states that psoriasis improves when patients fast or are on a low-energy diet. The article notes that this beneficial effect is likely due to a low intake of arachidonic acid. Arachidonic acid occurs mainly in fatty red meat, egg yolks and organ meat. Avoiding these foods may help relieve psoriasis symptoms. A vegetarian diet, which is naturally low in arachidonic acid, has also been beneficial for some psoriasis patients. Consult with your doctor before making dietary changes.
Include GLA
Gamma-linolenic acid, or GLA, is an omega-6 oil that may reduce inflammation. Reducing inflammation in the body may relieve psoriasis symptoms. GLA is available from several plant oils including evening primrose oil, black current seed oil and borage oil. Ask your doctor about using GLA dietary supplements for your psoriasis.
