Oh I don't know, wouldn't wright them off, a useful sugar hit if pushed and a nice addition to a snack. You could even mix a couple through a "pocket salad" - where you collect leaves and edibles in a pouch/pocket as you wander for eating at snack time. Just be careful. Remember over 20 odd years ago being out at this time of year on a training weekend with just a pocket knife and a lighter and being desperately short of edibles. Eventually came across a patch of brambles and got quite giddy with the sugar rush they gave. Sitting giggling in a damp thorny wet bramble patch sticks in the head, and a sugar hit can be quite important.
Hmmm. You're right, I guess as long as I'm careful, in that sort of situation of hunger, I might wolf some down in a frenzy of hunger, forgetting that they're poisonous..
