Preterm birth is the leading cause of perinatal morbidity and mortality in developed countries. Many innovation in neonatology have raised survival rates in the two past decades, but despite progress in neonatal intensive care, nutrition and growth of preterm infants are still critical points for neonatologists around the world and extrauterine growth restriction remains a common problem. Since growth is recognized as a major problem, in 2010, the European Society of Pediatric Gastroenterology and Nutrition published recommendations on enteral nutrition for preterm infants. The aim of this review is to revise nutritional needs of premature infants, taking into consideration the recommendations of ESPGHAN and the recent international literature.
