This article describes the effects of malnutrition on surgical disease and the metabolic response to injury, focusing on the relationship between nutritional status and the outcome of surgery. The article also shows the scientific evidence supporting the modern specialized nutritional therapy and its impact on surgical morbidity and mortality A review of the evidence on the relationship between diet and cancer is presented as a reason for surgeons to assume the nutritional and dietary advice of their own patients.
