The impact of diet on psoriasis is not well studied but it is of interest to many patients. A hypocaloric diet with corresponding weight loss can reduce psoriasis severity in overweight or obese patients and should be considered an important supplement to conventional therapy, as argued in this review. Gluten-free diet might improve severity of psoriasis in patients with coeliac disease or merely presence of coeliac-specific antibodies. Mediterranean diet might also be beneficial. Overall, studies do not support a beneficial effect of micronutrient supplements (i.e., vitamin D, selenium, vitamin B12) in patients with normal serum levels.
饮食对银屑病的影响尚未得到充分研究，但许多患者对此很感兴趣。如本综述所述，低热量饮食及相应的体重减轻可降低超重或肥胖患者的银屑病严重程度，应被视为传统治疗的重要补充。无麸质饮食可能改善患有乳糜泻或仅存在乳糜泻特异性抗体患者的银屑病严重程度。地中海饮食可能也有益处。总体而言，研究不支持血清水平正常的患者补充微量营养素（即维生素D、硒、维生素B12）会有有益效果。
