I haven't used it yet, but I picked up some LOCKTITE brand "Houseware Repair" from Home Depot for this same purpose. (It's a tube of glue. Costs just a few bucks.) It says it is for plates, porcelain, ceramics cups, etc, etc. It prominently says that it is "Dishwasher Safe". It also says the bond is inert (i.e., will not react with other chemicals) and safe once it is dry, so it should be safe to eat from. Good luck!
