Do remember the purpose of this study was to induce IBD with a proven agent.

The paper says guar gum is fine for healthy people, but taking it for four weeks set up substances in the colon wall that greatly exacerbated the IBD-making agent.

That said, if you already have IBD, guar gum would appear to increase the problem.

I see.

Thanks for that clarification.
