There are lots of different fibres with different functions, and I have ended up on eating a supplement that mostly lets the stool keep is moisture content, and I have not been constipated once since I started with it: hydrolysed guar gum. This way I can avoid other fibres which are horrible to my gut. I used to try eating fibre to keep from getting constipated, but often I happened to eat some fibre that instead gave me extremely runny stool.
