Hey pearlie,
Some of us have had some problems with uncooked fruit or veggies not digesting well and causing rougher/ scratchy bm's.
That may not be the case for you though... I couldn't eat any kind of nuts. They just didn't digest well and basically came out like they went in

Others have said they never had a problem

I've heard some say raw veggies caused problems for them. I ate apples in the beginning with my fissure. Things just weren't going so well for me as I didn't have a clue what I should or shouldn't be eating and just stopped eating anything that was raw or not cooked very soft...
Basically you may have to experiment and see how it goes for you. I'm sure juicing, pureeing or blending has to help but It's just hard to say what results it will give you personally. I know it can be really tough getting all the vitamins and nutrition when there's such a limit on what can be safe to eat...
ps...
I have a really hard time getting veggies into my little girl. I need to look into some smoothie recipes! Right now it's all green beans, broccoli (surprise) and green apples. She wont touch an apple that's not green and is very picky about her veggies?! Lol.
