fiber does not do well for me either, when i was younger the doctors told me to take fiber supplements to increase the amt i intake and it make me 100 times worse. over the years i just watched what i ate myself and learned what i could and could not tolerate. As well if your daughter is trying to put weight on high fibre will fill you up and make you feel full longer and therefor she will start to eat less and less often which im sure is not what you want either.
I would agree with everyone else if a low residue diet is working for her i wouldn't mess with it.
