Abstract    Minimally invasive surgery and enhanced recovery after surgery （ERAS） have been widely applied. The concept and goals of perioperative nutrition are also changed. Avoiding long time fasting during the perioperative period， taking carbohydrates 2 hours before operation， resuming oral eating as early as possible， and early nutritional treatment for patients with malnutrition or nutritional risk are the basic strategies of clinical nutrition therapy in today's ERAS era. A series of optimized perioperative nutrition management can reduce surgical stress damage， effectively preserve loss of lean body mass，decrease the incidence of complications and mortality，and achieve rapid recovery.
