When you eat more whole grains instead of processed ones (think brown rice instead of white), you may lower your level of C-reactive protein (CRP), a sign of inflammation in the body.
In people withrheumatoid arthritis (RA), CRP levels may go up during a flare-up. Doctors sometimes measure CRP to see how RA is progressing or to see how well treatment works.
Whole-wheat pasta and breads also contain an antioxidant called selenium. Some people with rheumatoid arthritis have lower levels of selenium in their blood.
Another advantage of eating whole grains is that their fiber fills you up, which makes it easier to manage your appetite. That can help you stay at a healthy weight so you don’t have extra pressure on your joints.
