Having had gut issues and cautious about what I would eat, I continued with gluten free bread and gluten free everything, ate scrambled eggs and started making smoothies since they are easily digested. You can find clean protein powders, add fruit like bananas and blueberries, I used nut milks without any additives, and collagen. Start with a small portion and see how you feel. During this time I also went dairy free (fat in dairy can sometimes be hard to digest) and sugar free (substituted Stevia as I need some sweetness). This really helped until I could find a doctor who would look for the cause of my symptoms and not treat just the symptoms. Mediation and doing breath work also helped with being stressed and anxious. Both stress and anxiety effect our gut. Read about the brain gut connection to learn about this.
Best to you, I know it’s difficult going through this.
