That would be me...cashews, peanuts, popcorn, tomatoes, cucumbers, poppy seeds...I've had 3 bouts with it and it is very painfull and uncomfortable...because of the inflamation in the colon you cannot poop which causes more discomfort...my doctor puts me on 1000 mg p/day of Cipro and 500 mg of Flagl antibiotics, soft, bland foods and clear liquids for about a week...after the antibiotics kick in and you can poop again you start feeling better...usually after a couple of days...next flair up and I have to have surgery to remove the part of my colon that has the diverticuli...about 6 inches in lenght.
