Psoriasis is a chronic condition that causes dry, rough, reddish areas on the skin of your scalp, lower back, knees, elbows and/or groin. According to the University of Maryland Medical Center, psoriasis affects more than 6 million Americans. In addition to topical creams, oral medications and stress management, a healthy diet, inclusive of particular foods, many help reduce the frequency or severity of your symptoms. For best results, seek specific guidance from your doctor or dietitian.
Whole Grains
Whole grains supply rich amounts of antioxidants -- nutrients that help your body protect itself from infections and disease. As fiber-rich, low-glycemic foods, meaning they have a mild impact on your blood sugar levels, whole grains enhance fullness between meals. Appetite and weight control are important, because excessive weight gain increases your risk for psoriasis symptoms, according to the Mayo Clinic. Examples of nutritious whole-grain foods include 100 percent whole grain breads, pasta and cold cereals, long-grain brown rice, wild rice, quinoa, barley, air-popped popcorn and oatmeal. For heightened benefits, replace refined carbohydrate sources, such as enriched flour products and sugary sweets, with whole-grain foods most often.
Plant-Based Protein
Plant-based protein sources, such as lentils, beans, split-peas and tofu, enhance lean tissue growth and repair and positive brain function, and provide heart-healthy alternatives to protein sources high in saturated fat, such as red meat and whole milk. Adopting a vegan lifestyle, which typically emphasizes plant-based protein, has reduced symptoms in some psoriasis sufferers, according to a research review published in the "British Journal of Dermatology" in October 2005. Healthy dishes based upon plant-based protein include baked, steamed or grilled tofu with vegetables, lentil or split-pea soup, chilled bean salads, low-fat vegetarian chili and vegetable and bean burritos served in whole-grain tortillas.
Fatty Fish, Flaxseed and Walnuts
Fatty fish, such as albacore tuna, salmon, herring, lake trout and flounder, are prime sources of omega-3 fatty acids -- healthy fats that promote positive heart health and brain function. Though research results are mixed, according to the University of Maryland Medical Center, omega-3 fats may help relieve pain, inflammation and redness associated with psoriasis. Incorporate grilled, baked, broiled or steamed fatty fish into nutritious meals routinely for maximum potential benefits.
If you do not consume fatty fish regularly, incorporate ground flaxseed and/or walnuts into your diet. Among the few plant-derived omega-3 fat sources, flaxseed and walnuts provide nutritious snacks or additions to other foods, such as baked goods, cereals, yogurt, salads and smoothies. Because the omega-3 fat benefits of flaxseed and walnuts are not as potent as those derived from fatty fish, regular intake of one or both foods is important.
