Is there a way to make a chemiluminescencent reaction that is safe for consumption by humans?

That is to say is it possible to make an item of food or drink that glows and is at worst non toxic? There are quite a few references available for general reactions of this kind (e.g. Wikipedia) but none of them are obviously safe to consume. It seems if I could find a way to make such things safe to consume then it would open the door to awesome punch and/or cake recipes.
