The role of the RD is to perform dietary assessments and provide counseling to help patients undergo dietary changes consistent with surgery. In anticipation of surgery, the RD helps patients prepare their kitchens with the needed appliances (eg, food processor, blender, and standardized measuring cups and spoons) and appropriate foods for a transition diet upon discharge from the hospital. The RD also pro- vides counseling for patients as they advance their diet during the early (3 months) postoperative period and, periodically thereafter, especially when the patient has difficulties meeting his or her nutritional goals
