I am sharing this in case someone still needs advice.
When I was diagnosed with RA, I made some changes to my diet and it really helped how I felt day to day. There is no single RA diet, but eating more vegetables, fruits, fish, nuts and whole foods seemed to reduce my joint pain and stiffness. Cutting down on sugary foods, processed meals and too much red meat also helped. I also saw a rheumatologist here in Singapore. Dr Leong Keng Hong is my doctor, and he explained that diet is part of managing RA along with proper treatment. Small diet changes can make a real difference.
