ABSTRACT
How do we identify and quantify dietary requirements? We begin by asking some basic questions about dietary requirements. What is a Dietary Reference Intake (DRI) and what is a Recommended Dietary Allowance (RDA)? How do we assess the needs for calcium, phosphorus, other minerals, and vitamin D? The heart of this discussion involves developing an understanding of the new guidelines for calcium and vitamin D that were released on November 30, 2010, and published in 2011 by the Institute of Medicine (IOM 2011).
