Psoriasis is a skin disorder where the skin produces new cells too quickly and the old cells are not shed, so there is a build up of tissue. The new cells are on top of the old, forming a swollen red patch on your skin that is usually covered with whitish scales. Psoriasis usually appears on your scalp, knees, elbows, back of your wrists and on your buttocks. The condition appears in cycles and is aggravated by certain foods. By knowing which foods to avoid, you can lessen your psoriasis flare-ups.
