Prunes work for me as well as bananas...lucky for me I haven't had "true" constipation yet...
Bananas actually affect people differnt ways, some get very constipated while others have the opposite effect, like the poster quoted, so just be careful with that one.

Pears and pear juice is what ive been recommended. DS and I both have poor digestion and use tham as part of our regular diet to help.
