I've been wondering how exactly can crohn's patients rebalance gut flora. It's been reported that people with IBD in general have much reduced diversity of gut bacteria, so can we restore the balance only by eating a wide range of healthy foods? If, for example, 20% of the species in my gut have completely died out, I don't think eating healthy would bring them back alive, or are there many "good" bacteria living in plants that when we eat them, it gets introduced back to our intestines? what do you think?
