Best Foods for Psoriasis

  1. Fatty Fish: Omega-3 fatty acids found in fish such as salmon, mackerel, and sardines are anti-inflammatory and can help reduce psoriasis flare-ups. Omega-3s work by decreasing the production of inflammatory chemicals in the body.
  2. Avocado: Avocados are not only delicious but are also packed with vitamins E and C, both known to support skin health. Furthermore, their natural fats are anti-inflammatory, which can help soothe psoriasis symptoms.
  3. Turmeric: Curcumin, the active compound in turmeric, has potent anti-inflammatory properties. Studies have shown that it can help reduce the symptoms of psoriasis. Consider incorporating turmeric into your dishes or taking curcumin supplements.
  4. Berries: Strawberries, blueberries, and raspberries are rich in antioxidants and vitamin C. These compounds can help combat inflammation, potentially easing psoriasis symptoms.
  5. Nuts and Seeds: Almonds, flaxseeds, and chia seeds are excellent sources of omega-3 and other nutrients that can help combat inflammation and promote healthy skin.
  6. Olive Oil: Olive oil is rich in antioxidants and has anti-inflammatory properties. Applying it directly to the skin can soothe psoriasis patches, and consuming it can promote overall skin health.
  7. Leafy Greens: Vegetables like spinach, kale, and Swiss chard are packed with vitamins A, C, and K. These nutrients can help support skin health and combat inflammation.
  8. Sweet Potatoes: These are a rich source of beta-carotene and antioxidants, both of which can support skin health and reduce inflammation.
  9. Broccoli: Broccoli is high in sulforaphane, an antioxidant that fights inflammation. Incorporating more of this vegetable into your diet can help manage psoriasis symptoms.
