This comprehensive text focuses on the nature of malnutrition in Cystic Fibrosis (CF), its manage-ment and prevention, and on the interrelated topic of gastroin-testinal manifestations of CF, many of which have only recently been characterized and defined. This valuable book serves as a basis for subsequent research and the institution of programs to reverse or prevent nutritional and gastrointestinal manifesta-tion. It is a welcome new text for direct-care givers of CF pa-tients, particularly physicians, gastroenterologists, and nutri-tionists as well as researchers.
