Glee Gum

Stocking stuffer / gift basket possibility for children on restricted diet:
"Glee Gum is made with all natural ingredients .... Our gum base has super chewy natural chicle harvested from Sapodilla trees in the rain forests of Central America."
They also have Verve's candy making kits

* of course, if you're not the parent or guardian of the child on a restricted diet you'd better check first before giving any sort of food gift.
