Bobert:

I have IBS and Diverticulosis. All I can say is eat plenty of fiber. Fruits veggies and stuff made with whole grains. Everybody's IBS is different but for me fiber works. I used to take Citricell fiber pills as recommended by the Doc but now I don't need them.

As far as certain foods that trigger it, I can't nail down anything in particular.

Eating more fiber will also help with Diverticulitis. It will prevent getting it if you don't have it yet and prevent Diverticulosis if you already have it. Diverticulosis is the condition of having diverticulii and Diverticulitis is when they get infected.

One food the be avoided for people with Diverticulitis is popcorn. Those little hulls get into the diverticulii and won't come out.
