Consider a vegetarian diet

At least one study found that people who ate a vegetarian or vegan diet reported an improvement in RA symptoms, including pain score, morning stiffness, and grip strength compared to those who didn’t.

However, because these diets are restrictive, many of the participants were unable to maintain them for the yearlong study period. 

If you can’t give up meat, then at least try to get a few more greens on your plate. The antioxidants, such as those found in green peas, bell peppers, and broccoli, may protect against tissue damage around the joints caused by free radicals.
