Psoriasis is a persistent skin inflammation that affects millions of Americans. Unfortunately, there is no cure. However, lifestyle factors, including regular exercise, stress management, topical medications and a healthy diet rich in omega-3 fatty acids, antioxidant nutrients (such as vitamins C and E) and B vitamins may offer some protection against flare-ups and pain.
What is it?
Normally, skin cells flake off from the surface of the body and are replaced by new ones formed in the deepest layer of the skin. This process is repeated every 28 days. For those suffering from psoriasis, new cells form much too quickly (4 to 5 days) to be shed--causing red, irritated, scaly, itchy spots on the skin.
Omega-3s
Omega-3 fatty acids, particularly those found in cold-water fish (such as mackerel, salmon, tuna and herring), can help reduce the inflammation that is a characteristic of psoriasis, particularly in milder cases. Take a daily fish oil supplement of 1,000 to 3,000 mg to help relieve your symptoms.
Helpful Vitamins
Vitamins E and C and beta-carotene stimulate the immune system, offering possible protection against developing psoriasis. People who eat orange, red and green vegetables and fruits appear likely to get it. Foods that offer the most antioxidant protection include carrots, sweet potatoes, sweet bell peppers, apricots, tomatoes and tomato products, fresh fruits and dark green, leafy vegetables, such as spinach and kelp.
B vitamins, such as thiamine, are beneficial because they play a role in the repair and healing of skin tissue. The richest source of vitamin B1 is pork. Wheat germ, sunflower seeds and whole wheat pasta are also good sources. Good food sources of pantothenic acid, another B vitamin important for healthy hair, skin and nails, are bananas and avocados.
Folic Acid
Some research has shown people with psoriasis have elevated homocysteine levels. This amino acid compound is naturally found in the bloodstream. Elevated levels increase the risk of heart disease. In a study published by the British Journal of Dermatology, researchers found blood homocysteine levels correlated directly with the disease's severity. However, folic acid (vitamin B9) levels were inversely correlated with psoriasis severity. Folic acid helps regulate and decrease homocysteine levels. Foods fortified with folic acid include breads and cereals. Foods rich in the natural form of folic acid (folate) include beans, legumes and dark green, leafy vegetables. Add these foods to your diet.
Healing Herbs and Vitamin D
Herbs are not just for flavoring foods. They offer healthy benefits whether taken in with food or applied topically. For instance, the gel derived from the aloe plant is known for its soothing skin benefits. Using aloe gel topically may reduce or alleviate psoriasis symptoms. In addition, the active form of vitamin D has been successfully used in the topical treatment of psoriasis.
