I mush my fruit up so that they cannot pick and choose their favorites and so that any vitamin supplements are evenly distributed throughout. I suppose it's like a fruity nectar mix, fruit is soft anyway so I'm not against mushing it up. Mine get hard food in the form of cat biscuits, they're placed on top of the fruit mush so they're still nice and crunchy when the suggies get to them

branches as said earlier are good too.
The soft diets that do concern me are the ones that contain no crunch at all like the leadbeater diets and they are high in sugar so will coat the teeth, and then add the fruit sugars and acids on top of that, their little mouths must feel just awful!
You know I read on the large US forum once that we shouldn't be feeding hard bugs like beetles because the exoskeleton might scratch the roof of the mouth and cause infection!!! How BAD is that
