The field of pediatric nutrition has developed into an area essential to components of academic pediatric program throughout the world. Among the pediatric texts available, none deals with the physiologic or pathophysiologic basis of nutrition in pediatric health and disease in children of all ages. Nutrition in Pediatrics, Fourth Edition , fills this void, extending physiologic and pathophysiologic considerations to their coverage of nutritional needs with respect to disease and covers diagnosis of nutritional imbalance and management as well. The 4th edition includes an entirely new section on pediatric obesity: epidemiology, pathophysiology, assessment and treatment. It includes new chapters on celiac disease, food allergies and iron. This edition includes updated growth curves, including the newly released WHO growth curves for exclusively breastfed infants. It contains expanded and updated chapters on international nutrition, including protein energy malnutrition and community nutrition. This edition of this textbook continues to be dedicated to establishing a comprehensive and accessible approach to pediatric nutrition. Sections include basic concepts in the development of nutritional requirements of infants and children and a pathophysiology section examining cardinal manifestations and development. These sections will augment a comprehensive approach to perinatal nutrition, nutrition of specific disease states and nutritional management.
