If you have psoriasis, you may find that certain foods cause flare-ups or make your condition worse, while others seem to ease your symptoms. Scientific data has not shown that any specific diet is guaranteed to improve or worsen psoriasis.
Try these diet strategies to find out what works best for you.
Consider these foods reported by some people as positively affecting their psoriasis:
Omega-3 essential fatty acids, which are found in fatty fish including salmon, mackerel and sardines, are believed to reduce inflammation. Since psoriasis is caused by an overactive immune system, reducing inflammation may reduce psoriasis symptoms.
Plant sources of omega-3s include flaxseed, olive oil, pumpkin seeds and walnuts.
People with psoriasis can also benefit from a diet rich in omega-3 fatty acids to reduce their risk of heart disease.
Fruits and Veggies
Colorful fruits and vegetables contain vitamin A which may help reduce inflammation and is known to improve the health of skin. Try to include carrots, squash, sweet potatoes, kale, spinach and broccoli in your diet.
Fruits that reduce inflammation include blueberries, mangoes, strawberries and figs.
Whole grains contain antioxidants and fiber that help fight inflammation. Good sources of whole grains include whole-grain bread, cereal and pasta, as well as oatmeal and brown rice.
Some herbs are believed to help reduce inflammation and support the body’s immune system. Some people report reduced psoriasis symptoms with evening primrose oil, milk thistle and oregano oil.
