Editing Dietary Reference Intake (section)

==Standard of evidence==
In September 2007, the Institute of Medicine held a workshop entitled "The Development of DRIs 1994–2004: Lessons Learned and New Challenges".<ref>{{cite book|url=https://www.nap.edu/read/12086/chapter/1|title=Read "The Development of DRIs 1994-2004: Lessons Learned and New Challenges: Workshop Summary" at NAP.edu|year=2008|doi=10.17226/12086|isbn=978-0-309-11562-9|via=www.nap.edu}}</ref>  At that meeting, several speakers stated that the current Dietary Recommended Intakes (DRI's) were largely based upon the very lowest rank in the [[Levels of evidence|quality of evidence pyramid]], that is, opinion, rather than the highest level – randomized controlled clinical trials.  Speakers called for a higher standard of evidence to be utilized when making dietary recommendations. The only DRIs to have been revised since that meeting until 2011 are vitamin D and calcium.<ref name="vitD-Calcium2"/>
