Although researchers haven’t found a definitive link between diet and psoriasis, certain foods may trigger flares in some people at large. If you believe a particularized food or food group affects your flesh, try ridding yourself of the offending food item for a period of time.. Other than that, the greatest dieting strategy is the same one that’s recommended for most people: well-balanced meals that emphasize fresh fruits and vegetables, whole grains and meats that are low fat. Especially helpful are the right kinds of lipids, especially omega-three fatty acids, which are important for healthy skin. Your body doesn’t produce omega-3s, instead you obtain them from food or supplements. The best dietary sources are fatty fish or fish oil capsules particularly salmon and salmon oil, flaxseeds and flaxseed oil, walnuts, and soybean and canola oils. Some dark green leafy vegetables such as spinach, kale and broccoli contain modest amounts of omega-3s. Incorporating these foods into your daily food intake can help dry skin, but it does even more for your overall health. Omega-3s lower triglyceride levels and mitigate your risk of heart hit and stroke. They also lower blood pressure and may reduce the pain and inflammation of psoriatic arthritis.
