Overview

A powerful all-in-one resource for students, clinicians and researchers, Nelms/Roberts' NUTRITION THERAPY & PATHOPHYSIOLOGY, Cengage International Edition, 5th Edition, clearly connects nutrition therapy practices and expected outcomes to underlying disease processes at every level -- from cells to organ systems. Emphasizing the nutrition care process, it reflects the latest research, evidence-based practice guidelines and scope and standards of dietetics practice. Detailed illustrations enhance student understanding of disease pathophysiology and progression, surgical procedures and treatment protocols, while Practitioner Interviews provide real-world insight for working with patients. Emphasizing concepts and advice most useful to students, it's the ideal text for instructors who want to focus on "clinical" or "diet therapy" topics without basic nutrition chapters.
