The box of pie-sized Jell-O Chocolate Pudding we’ve got sitting here waiting to make the pie on Tuesday.  In the corner it’s advertised: “A Good Source of Calcium (as Prepared)”

The parenthetical bit is really just a smaller typeface on the box.

As prepared?  As in… with milk?  Yep, a quick check of the nutrition facts panel confirms there’s absolutely no calcium in pudding.  However, if you mix it with milk, you’ll get to have all the calcium that was already in the milk.
