The Nutrition and Health series has been very fortunate to have each of the volumes recognized by rating services, such as Doody's, as valuable contributions for health professionals and individuals interested in the most up-to-date and balanced information from the experts in nutrition. These independent accolades may have occurred because the Nutrition and Health series has as its overriding mission to provide health profession­ als with texts that are considered essential because each book includes: (1) a synthesis of the state of the science, (2) timely, in-depth reviews by the leading researchers in their respective fields, (3) extensive, up-to-date fully annotated reference lists, (4) a detailed index, (5) relevant tables and figures, (6) identification of paradigm shifts and the con­ sequences, (7) virtually no overlap of information between chapters, but targeted, inter­ chapterreferrals, (8) suggestions of areas for future research, and (9) balanced, data-driven answers to patient questions, which are based upon the totality of evidence rather than the findings of any single study. The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate.
