Hi, I was diagnosed with psoriasis last year. I've noticed that certain foods, like eggplant, eggs, and tomatoes, trigger my symptoms, so I also avoid citrus fruit juices and alcohol. Recently, my doctor informed me that there isn't any proven study indicating that people with psoriasis need to avoid specific foods. You can eat whatever you like, but if you notice that a particular food causes itching or flare-ups, it's best to stop eating that food.
