Diverticulitis Diet – 10 Worst Diverticulitis Foods

5. Red Meat

It takes a long time for the human digestive system to process protein, especially red meat. In a diet for diverticulitis, it is best to eliminate red meat which is high in saturated fat. Take a break from all protein during painful episodes and slowly add lighter proteins, like chicken or turkey breast, fish, or vegetarian sources like tofu and tempeh, back into your diet when symptoms subside.
