Psoriasis is a common inflammatory skin condition characterized by reddish-pink patches with silver scales on your scalp, elbows, back, knees or groin. More than 6 million Americans have psoriasis, according to the University of Maryland Medical Center. Though no known cure exists, topical creams, medications, ultraviolet light therapy, physical activity and a healthy diet may improve your symptoms.
Protein-Rich Foods
Protein provides amino acids -- the building blocks of lean tissue. A diet high in protein, particularly animal-derived protein, is linked with increased psoriasis symptoms, according to a report published in the "Indian Journal of Dermatology" in 2010. Red meat and high-fat dairy products contain omega-6 fatty acids, which may increase skin inflammation and your risk for symptom flareups. Coldwater fish, such as salmon, trout, halibut and sardines, on the other hand, provide omega-3 fatty acids, which may help reduce inflammation. For potential benefits, cut back on high-fat protein sources and opt for fish, beans and lentils more often.
Starches
Starches, such as breads, cereals, rice and pasta, provide glucose -- your body's main dietary source of energy. Whole grain starches promote positive blood sugar levels and provide more fiber and nutrients than refined starches, such as white bread. Many people with psoriasis struggle with blood sugar imbalances, according to author of "The Psoriasis Cure" Lisa LeVan, who recommends whole grains as valuable sources of zinc and for anti-inflammatory benefits. For best results, examine nutritional labels on foods and choose those that list whole grains, such as whole wheat, oats or long-grain brown rice, as main ingredients. If gluten, a protein found in wheat, barley and rye, worsen your symptoms, stick to gluten-free foods, such as rice, popcorn and oats.
Fruits and Vegetables
Fruits and vegetables provide antioxidants, which support a strong-functioning immune system. As relatively low calorie, fiber rich foods, increasing your intake of fruits and vegetables may help you manage your calorie intake and weight. Low calorie diets may improve psoriasis symptoms, according to the "Indian Journal of Dermatology" report. Leafy green vegetables, broccoli, cantaloupe and citrus fruits provide the added benefit of folate -- a B vitamin some people with psoriasis lack. Choose whole fruits and vegetables over juices and sweetened canned or dried fruit, which provide fewer nutrients and more calories.
Salty Foods
The body requires sodium for proper function. However, many Americans consume excessive amounts. Salty foods, such as potato chips, french fries, crackers and pretzels, and canned soups, tomato juice and frozen entrees often contain exorbitant amounts of sodium, which may increase inflammation. Certain psoriasis medications, such as corticosteroids, can cause imbalanced mineral levels in your body, according to LeVan. Consuming too much salt can worsen these effects. Other psoriasis medications can cause iodine deficiencies. If this is the case for you, iodized salt and seafood may help prevent complications. If you're unsure whether salty foods are a concern for you, seek guidance from your doctor.
