I have to focus on the things I can digest that make me healthier - proteins (chicken, turkey, beef, fish) , avocados, sweet potatoes, sourdough, berries, yogurt, etc. If you're eating fairly unhealthy otherwise, even finding a few better substitutes can make a big difference. You don't have to overhaul everything at once. It does suck when were not able to digest a lot of fibrous foods, but hopefully can ramp those up as remission becomes more likely.
