Updating and supplanting the 1997 edition, this reference compiles research findings on the dietary needs and biological activities of the two essential nutrients, particularly addressing recent controversies over their use. After an introduction and overviews of calcium and vitamin D, it discusses potential indicators of adequacy and the selection of indicators, dietary reference intakes for adequacy, tolerable upper intake levels, dietary intake assessment, implications and special concerns, and information gaps and research needs. The CD contains appendices B-K (also available online) which, though listed in the table of contents, are not printed in the book. Annotation ©2011 Book News, Inc., Portland, OR (booknews.com)
