The more serious your episode of diverticulitis, the less fiber you should eat. No peas (skin), no blueberries (skin), etc, carrots very well cooked are good. When I was awaiting my colon resection because of a perforated colon, caused by diverticulitis, I would make an instant pot chicken soup with carrots and chicken thighs. I could eat the soft carrots and the juicy, but cooked chicken. I would add noodles to the broth another night and just have soup. When feeling better, I'd take the soup, make a gravy with it and have an open-faced hot chicken sandwich smothered in soup gravy with Bob Evans ready made mashed potatoes... all low fiber, several different meals for the week. I tried to keep portions smaller and eat more frequently.
