Foods to avoid with diverticulitis. In the past, doctors had recommended that people with diverticular disease (diverticulosis or diverticulitis) avoid hard-to-digest foods such as nuts, corn, popcorn or seeds, because of the risk that these foods may get stuck in the diverticula and lead to inflammation.
The best way to avoid developing diverticulosis in the first place (aside from the impossibility of staying young) is by eating a proper healthy diet With plenty of fiber. A diet high in fiber keeps the bowels moving, keeps the pressure within the colon within normal limits, and slows or stops the formation of diverticula.
