Rheumatoid is different from the plain arthritis. I only know about the one from autoimmune issues. Pretty much cut out any and all things that can a cause inflammation. I did the AIP (autoimmune protocol) one for a while and eventually modified it based on what actually caused me issues and what didn't. I also have always had blood sugar issues and thyroid problems from other vax induced autoimmune problems so it's probably way different for someone else. I need a very meat heavy diet and for my mom it was more plant based (not vegan by any stretch but she had gout flare ups eating like me). She doesn't/didn't have other autoimmune problems. She also did the AIP and modified it. I end up 'sensitive' to anything I eat too much of, so say eating green beans at lunch every day for 3 days can cause me problems. I constantly have to change stuff up. I can have a few eggs a week but not daily. It's completely weird for me.
