Psoriasis is a common skin condition that causes red, scaly skin patches. Five percent of people with psoriasis develop psoriatic arthritis, according to the University of Maryland Medical Center, which causes swelling, pain and stiffness in your joints. Symptoms of both conditions may come and go episodically and flare up in times of stress. In addition to medical treatments, a healthy diet, inclusive of certain foods, may help minimize your symptoms.
Whole Grains
Whole grains provide significant amounts of vitamins, minerals and fiber. As low-glycemic foods, whole grains digest slower and provide greater satiation than refined grains, such as white flour. Eating a nutritious, plant-based diet that emphasizes whole grains is a useful means of managing your weight, which is important since excess weight gain adds undue strain to your joints, according to MayoClinic.com. For heightened benefits, replace enriched breads, pasta and snack foods in your diet with whole grains. Examples of nutritious whole-grain foods include 100 percent whole-grain breads, pasta and cold cereals as well as pearled barley, quinoa, brown rice, wild rice, steel-cut oatmeal and air-popped popcorn.
Cold-Water Fish
Cold-water fish, such as salmon, albacore tuna, herring, halibut, mackerel, lake trout, flounder and sardines, are top food sources of omega-3 fatty acids -- essential fats associated with positive brain function and heart health. Omega-3 fats may help reduce inflammation associated with arthritis and psoriasis, according to a report published in the "Journal of the American College of Nutrition" in 2002. Since fatty red meats may worsen inflammation, rely upon cold-water fish as a protein source more often. Healthy cooking methods include broiling, steaming, baking and grilling fish atop nonstick cooking spray or light amounts of olive oil.
Flaxseed, Walnuts and Canola Oil
Second only to cold-water fish, flaxseed, walnuts and canola oil provide valuable omega-3 fat benefits. Dietary fats also promote nutrient absorption, so consume flaxseed, walnuts and canola oil as parts of nutritious meals for added wellness benefits. The University of Maryland Medical Center recommends grinding whole flaxseed within two days of use and storing it your refrigerator for preserved freshness. Sprinkle ground flaxseed atop yogurt, hot or cold cereal, or muffins before baking to add anti-inflammatory benefits. Since flaxseed is also high in fiber, regular consumption may support appetite control and digestive function. Enjoy walnuts on their own or as healthy additions to salads, snack mixes and baked goods. Canola oil provides a heart-healthy alternative to margarine, shortening and butter.
Fruits and Vegetables
Fruits and vegetables are prime sources of antioxidants -- nutrients that help your body defend itself from infections and disease. As nutritious, fiber-rich, low-calorie foods, fruits and vegetables support weight management for psoriatic arthritis sufferers, according to MayoClinic.com. Fresh varieties may also help alleviate inflammation. For best results, choose colorful fruits and vegetables over high-calorie, low-nutrients foods, such as candy, fried chips and pastries, most often. Choose whole varieties over juices and canned fruit stored in heavy syrup, which provide fewer nutritional benefits and may offset blood sugar levels and appetite control. Fruits and vegetables particularly high in protective nutrients include berries, citrus fruits, kiwi, cantaloupe, tomatoes, leafy greens, broccoli, Brussels sprouts, bell peppers and winter squash.
