I have both diverticulosis and a tortuous colon. The colon is from adhesions from a colon resection from a perforated colon and peritonitis from diverticulitis. Fiber One cereal is my saviour! I don't eat popcorn, which is the worst food for diverticulosis; but I eat pretty much everything else and have no symptons from either condition. The secret is to eat a lot of fiber. I just had a colonoscopy, and was put to sleep with propofol ( think Michael Jackson ), but had no ill effects. Even though in three colonoscopies I have not had polyps, the doctor says I should have a colonoscopy every 5 years. If you have any kind of digestive trouble try Fiber One. I never miss a day!
