Well, I always suspected that about lima beans. I haven't tried any as an adult, I confess.

As far as the, um, non-digesting of certain vegetables... (let's put that delicately, shall we? Or we have 'Spaw back in here discussing end-products again) that's basically the whole point of the high-fiber veggies. And it depends on to which degree the said veggie has been cooked and pulverized. If you sit down and eat a whole bag of raw carrots with the minimum of chewing, you're going to be seeing those carrots again later...

This is another thing that freaks out many unsuspecting parents of toddlers, especially if they're having a touch of the trots to start with. Things tend to come out in the diaper looking pretty much like they did went they went down, as toddlers seem to view chewing as optional. Or, as one of my partners so succinctly put it the other day, "If the kid's got diarrhea and you feed him green beans, he's gonna poop green beans. If you feed him raisins, he's gonna poop grapes."
