I am not sure about diverticulitis diet, but I have IBS too, I am suppose to eat Fiber One cereal...it tastes bad to me (too sweet), but it has helped ease some of my pain. It is the highest fiber cereal on the market, but I do not like the nutrasweet being in it, I had cleansed my body of nutrasweet, now I have to put it back in. Good Luck
