Diverticulitis Diet – 10 Worst Diverticulitis Foods

10. Seeds, Popcorn and Coconut

While the verdict is still out on whether or not eating seeds, popcorn and coconut cause diverticulitis attacks, many people report that they have severe discomfort after eating these items. Tiny seeds like sesame and poppy seeds, or bits of popcorn and coconut, could possibly become trapped in diverticula and cause inflammation. It hasn’t been proven scientifically that this is true, but it is certainly better to be safe than sorry and cut them out of your diet until you are feeling better.
