I was on a low-fiber/low-residue diet for three years. It was incredibly boring, but, along with the 6MP, it seems to have made my stricture disappear. (Admittedly, that would mean that we caught the stricture when it was still inflammation and edema, rather than scar tissue.) Basically, you just eat carbohydrates and very well cooked veggies and fruit. Dairy, if you aren't lactose intolerant--and I suppose meat or fish (I'm a vegetarian, so I don't know). No whole grains, nuts, or any of the usual Crohn's no-nos. I told people that it was the diet you asked for when you were four years old and someone asked you what you'd like to eat for the rest of your life. Lots of mac and cheese, white bread, apple juice . . . ugh. But it worked.
