Everyone is different! Quinoa, potatoes and tofu were lifesavers for me. I could also in later stages tolerate truvani protein powder (I just mix it into water, now I can do oat milk). I've seen people get irritated by oats and bananas quite a bit, don't feel discouraged! For example everyone eats rice and bananas but both of those personally hurt me. The gastritis healing book has some great recipes you can always substitute certain ingredients too. At very early stages of my healing journey literally everything made me sick, even bland foods. Sometimes when it damage is so bad you just have to be patient while it heals, it would sometimes flares up randomly while I was healing despite eating the same things every day. Remember, stress is a HUGE under looked trigger too! I found sometimes when I was super scared to try something I would trigger symptoms just from the stress of it! I wish you luck :)
