Nutrition is an interdisci- plinary, interprofessional field par excellence. It is noted by its broad range and diversity. We trust that the titles and authorship in this series will reflect that range and diversity. Published for a scholarly audience, the volumes in the CRC Series in Modern Nutrition are designed to explain, review, and explore present knowledge and recent trends, developments, and advances in nutrition. As such, they will also appeal to the educated general reader. The format for the series will vary with the needs of the author and the topic, including, but not limited to, edited volumes, monographs, handbooks, and texts. Contributors from any bona fide area of nutrition, including the con- troversial, are welcome. We welcome the contribution Vegetarian Nutrition, edited by Joan Sabaté with the collaboration of Rosemary Ratzin-Turner. There is a great deal of interest regarding vegetarianism as an alternate dietary pattern. This book discusses that issue in detail and will appeal to nutritionists, dietitians, physicians, students, and professionals in the health sciences and health services arenas.

As a result, numerous scientific and professional questions have arisen. Currently, professional interest in vegetarian nutrition has reached unprecedented levels. This is only partly explained by the growing number of vegetarians and the increased popularity of vegetarian diets. As disease patterns shifted away from nutrient deficiencies and toward diet-related chronic diseases, vegetarian nutrition research also changed emphasis, and the benefits of vegetarian diets have begun to emerge. In the past 30 years, scientific endeavors in the area of vegetarian nutrition seem to have progressively shifted from investigating concerns held by nutritionists and other health professionals to a fertile area of investigation in which creative solutions for various medical conditions and preventive approaches to chronic diseases may be found. Despite this broadening shift in the focus and study of nutrition, current knowledge regarding the relationship between vegetarian diets and human health is far from complete. However, scientific advances made during the last few decades have noticeably changed the role of vegetarian diets and other diets largely based on plant foods in human nutrition and public health. This book on vegetarian nutrition is an attempt to summarize the large body of literature accumulated on the topic. Although most of the information presented in this book centers on the dietary practices of vegetarians, it has sweeping implications for the general population. In the past few years, scientific literature has exten- sively reported on the health effects of plant foods such as whole grains, legumes, vegetables, fruits, and nuts. Although they are essential compo- nents, these dietary factors are not unique to vegetarian diets. Thus, the information reviewed on plant foods and health has direct applications for all persons.
