==Q: Dietary minerals vs. nondietary minerals== 

 This article lists some things which are "dietary minerals", and then some other elements which aren't (like calcium).  To count as a dietary mineral, does something have to scientifically be a mineral (crystalline structure, etc.)?  This page seems to disagree with the mineral page on whether calcium is a dietary mineral (that page says it is).    8 July 2005 13:47 (UTC)
