Even though there's no proof they work, you'll find dozens of psoriasis diets described in books and on websites. At some point almost every food has been blamed for an outbreak -- sugar, junk food, wheat products, tomatoes, coffee, and eggs are often called out.
There are just as many theories about what foods might be good, among them herbal teas, some fruit juices, and fish oil supplements. It’s no surprise that psoriasis diets disagree about what's good and what's bad.
