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.
Lifestyle Changes. For a milder case of diverticulitis, once you have your medications in hand, the best thing you can do is climb into bed and rest until youâre feeling better. Watch your diet, too. Initially, youâll need to stay on liquids and soft foods. In a few days, your doctor will probably start you on a low-fibre diet.
