If you're thinking about trying a psoriasis diet, talk to your doctor first. He’ll probably tell you any diet that cuts down on the amount of junk food and alcohol you eat and drink is OK.
Stay away from extreme diets that claim to cure psoriasis. They won't work. Avoid those that require you to fast, get enemas, or take other extreme steps. These diets can be time-consuming, expensive, hard to maintain, and sometimes, even dangerous.
Don't assume that supplements you buy in the supermarket are helpful or even safe. Taking supplements in extremely high doses, which some shady psoriasis "diet experts" suggest, can be toxic. Always talk to your doctor before going on any diets or using any supplements or alternative medicines.
