This scoping review explores the role of diet in managing psoriasis, a chronic inflammatory skin disease affecting 60 million people globally. It highlights that people with psoriasis (PLwP) often consume higher fat and lower fiber diets, with lower psoriasis severity linked to higher fiber intake. While PLwP believe diet impacts their symptoms and often adopt restrictive diets, systematic reviews and RCTs show dietary improvements mainly benefit specific groups, such as those with obesity or coeliac disease. The evidence for supplements is inconclusive, and current guidance focuses on weight loss. The review calls for larger, controlled trials to establish effective dietary strategies for all PLwP and suggests that understanding diet modification and experiences can improve holistic psoriasis care.
