Psoriasis is chronic skin condition that causes dry, reddish, scaly patches on the scalp, knees, elbows, lower back, groin or other areas. A healthy diet that supports weight management is important for psoriasis sufferers, according to the National Psoriasis Foundation. A healthy diet can also strengthen your immune system and help prevent infections and disease. For optimum results, seek specified guidance from a qualified health-care professional.
Fruits and Vegetables
Fruits and vegetables provide rich amounts of disease-fighting antioxidants. As fiber-rich, low-calorie foods, fruits and vegetables can help you stay satiated between meals and enhance weight management. To obtain appropriate amounts of vitamins, minerals and antioxidants, the American Dietetic Association recommends eating at least 2 cups of fruit and 2-1/2 cups of vegetables daily. Consume colorful vegetables and fruits most often, which tend to provide richest amounts of nutrients. Examples of nutrient-rich fruits and vegetables include berries, citrus fruits, apples, pears, plumbs, bananas, kiwi, papaya, cantaloupe, tomatoes, spinach, kale, broccoli, sweet potatoes, baked potatoes, string beans, Brussels spouts, bell peppers and carrots.
Whole grains, such as oats, wild rice, brown rice, quinoa, whole wheat, popcorn and barley, provide rich amounts of nutrients and fiber. As low-glycemic carbohydrate options, whole-grain foods have a milder impact on blood sugar levels than processed grains. For this reason, whole grains can enhance appetite control, weight management, sustained energy levels and digestive health. Numerous whole grains provide significant amounts of folate -- a B vitamin important for cell production and physical growth and development. According to the University of Maryland Medical Center, a medication often used to treat psoriasis known as methotrexate can reduce your body's supply of folate. Whole-grain foods rich in folate include fortified cereals, brown rice and whole-grain bread.
Lean Protein and Fatty Fish
Protein provides amino acids, which contribute to lean tissue production and tissue repair. The National Psoriasis Foundation recommends watching your fat and cholesterol intake. Since red, processed and fried meats contain dense amounts of saturated fat, opt for lean sources most often. Lean protein-rich foods include egg whites, low-fat dairy products, fish, skinless white-meat poultry and legumes, such as beans and lentils. Fatty fish, such as Alaskan salmon, tuna, herring, halibut, lake trout, mackerel and flounder are rich in omega-3 fatty acids -- healthy fats known to reduce inflammation and enhance cardiovascular health. Consuming fatty fish regularly may help reduce inflammation of your skin and your joints. Since psoriasis increases your risk for arthritis, omega-3 fatty acids may provide multiple benefits.
