Reading and my discussions with vegans has been helpful, inflammation and gut health are highly correlated. My zoom meeting with a nutritionist was expensive and disappointing. She was selling supplements.
After many hours of research on autoimmune and GERD gut health and months of trial and error I asked my rheumatologist questions and found his responses helpful.
Fortunately I do not get a reaction from diary and I like the taste of Keifer. Before each meal I drink 2-3 ounces of 1% fat no added sugar plain Keifer. Nuts are not an option, I don't like the smell, taste or texture.
Eating at a chain restaurant doesn't work for me and sometimes I don't have a choice. I'm comfortable not eating - this will not be my last meal. It can be difficult finding something to eat at a fine restaurant and I don't want to get sick. Now I call ahead of time and ask if they will cook unseasoned protein and fresh vegetables on a clean grill. My friends are kind, let me determine the restaurant choices.
With that said I believe flexibility is important, just like autoimmune symptoms vary person to person so do the reactions to different foods. I found removing one food product from my diet and adding it back in a month later helps me figure out what foods I can eat without a reaction. My diet is a moving target, and viable options are more limited than they were a year ago. I work at being creative and thinking outside of the box.
The results are not perfect, by working on diet I hope to reduce the flare ups and intensity by 50%. Autoimmune drugs are Plaquenil and Cellcept.
May your health improve and you find doctors that give you confidence that your health plan is appropriate. Be well.
