> > 7. Vitamins are included, but this is the part I don't know about. I don't really know if vitamins should count as food. Would a vitamin work to satiate hunger at least as well as a breath mint does? And yet, while it's ingested and digested, and it's intended to be ingested and digested, it's not treated as sustenance.

Oh. Well, there you go. A definition of food that, IMHO, appropriately excludes vitamins, drugs, and gum, and which appropriately includes candy, vegetables, and, only when eaten, playdough.
