RESUMEN
Many dermatologic diseases are chronic with no definitive cure. For some diseases, the etiology is not completely understood, with treatment being difficult and associated with side effects. In such cases, patients may try alternative treatments to prevent onset, reduce symptom severity, or prevent reoccurrence of a disease. Dietary modification, through supplementation and exclusion, is an extremely popular treatment modality for patients with dermatologic conditions. It is, therefore, important for dermatologists to be aware of the growing body of literature pertaining to nutrition and skin disease to appropriately inform patients on benefits and harms of specific dietary interventions. We address the role of nutrition in psoriasis, atopic dermatitis, urticaria, and bullous diseases and specific dietary modifications as an adjunct or alternative to conventional therapy.

Nutritional supplementation may provide a viable treatment alternative in patients with psoriasis. Randomized, controlled trials have shown the effectiveness of topical vitamin A and D derivatives, intravenous ω-3 fatty acids, oral inositol, and various combined therapies. Dual therapies of ultraviolet B phototherapy and fish oil, retinoids and thiazolidinediones, and cyclosporine and a low-calorie diet were effective in the treatment of psoriasis in randomized, controlled trials. This contribution also reviews the potential negative effect of alcohol and the potential positive effects of vitamin B(12), selenium, retinoic acid metabolism-blocking agents, and a gluten-free diet in the treatment of psoriasis.
