Hi Monica,
The foods I have either completely eliminated or try to reduce as much as possible: gluten, dairy, processed industrial oils (canola, soybean etc) and processed sugars. I also limit red meat.
I focus mostly on whole foods, lots of vegetables, healthy fats and carbs, grass-fed or wild-caught animal proteins.
Those changes have been and are still very beneficial to reduce my pain. I've been mostly pain free the last two years. So definitely worth it to reduce inflammation via this way 😀
It takes time and patience but you really get used to eating this way.
Let me know if you have any questions. Best of luck!
