Soluble and Insoluble fibre.

Hi all, I'm getting to the bottom of this fibre ratio, so I've been having quite a few Chia Seeds, high in soluble fibre, seems to work well to stop bloating, only downside large stools pretty tough to pass, soluble fibre slows transit time, but I was ok, so now I'm adding Bran which is high in insoluble fibre and speeds up transit time, so basically I'm trying to find the right ratio of fibre, I'm trying more or less 50 50 just now, will post results for better or worse.
