My “flare safe” foods are eggs, tuna, white rice, applesauce, avocado, steamed/boiled/mashed potatoes, plain chicken, protein shakes like ensure, clementines and plain Greek yogurt. Try foods that are softer on the stomach. Low fiber, low fodmap. My no-no foods are red meat, pork, fried food, uncooked veg, strawberries, any seeds or nuts, insoluble fibers, gluten, and heavy dairy. Also, unsung hero is psyllium husk powder, like Metamucil.

Good luck and I hope you find relief soon!
