While numerous studies have highlighted the need to approach anorexia nervosa from a multidisciplinary perspective, the dietary and nutritional aspects of the disorder are rarely considered in depth. Basic guidelines to monitor food intake of patients, are available. A literature review was performed in Medline, searching for articles related to the dietary and nutritional management of anorexia nervosa and published over the last five years. The final analysis focused on 102 articles. This review summarizes the different therapeutic contexts and objectives, nutritional support, the use of dietary supplements, the role of artificial nutrition, refeeding syndrome, involuntary treatment and nutritional education.
