230x9 is pretty damn good!
Not trying to give you diet advice but I'll tell you something my wife and I noticed about our son with Crohns (he knows it too). If he eats something with lots of sugar, like donuts, cookies, etc., he ends up in the bathroom a lot more often than on the days he doesn't. Dr said it's probably due to the gut bacteria (and it's different for those with IBS and Crohns) and how it interacts with sugar.
Seems odd that its just heavy sugar items as he can eat lots of bread, potatoes, chips, etc., with lots of simple carbs and it doesn't bother him all that much. Doesn't mean he doesn't eat donuts, etc., but it's only a couple times a week.
