Since the first edition was published in 1990, much has changed
in the science of nutrition. But the purpose of the text to provide thorough
coverage of normal metabolism for upper-division nutrition students - remains the
same. We continue to strive for a level of detail and scope of material that
satisfy the needs of both instructors and students. With each succeeding
edition, we have responded to suggestions from instructors, content reviewers,
and students that have improved the text by enhancing the clarity of the
material and by ensuring accuracy. In addition, we have included the latest and
most pertinent nutrition science available to provide future nutrition
professionals with the fundamental information vital to their careers and to provide
the basis for assimilating new scientific discoveries.
Just as the body of information on nutrition science has increased,
so has the team of authors working on this text. Dr. James Groff and Dr. Sara
Hunt coauthored the first edition. In subsequent editions, Dr. Sareen Gropper
became a coauthor as Dr. Hunt entered retirement. In the fourth edition, Dr.
Jack L. Smith joined the author team now led by Dr. Gropper. In this seventh
edition, Dr. Tim Carr has provided additional expertise and co-authorship on
several chapters.
