Iron-fortified cereal contains iron... particles!

Well done (except for misspelling "coarse" at the end), interesting, and somewhat unexpected. Some of you will want to locate your keyboard's "mute" button...

I believe I have always assumed that the "iron" in such food items was organic iron, not metallic. I wonder if the "%RDA" on the label reflects the small proportion of such particulate metal one would normally absorb, or the gross metal content.
