People with rheumatoid arthritis (RA) have immune systems that harm the lining of their joints. This damage causes chronic inflammation, stiffness, and pain.
Research shows the Mediterranean diet's tasty fare -- like olive oil, fish, greens, and other vegetables -- can lower inflammation, which is good for your whole body.
In one study of women with RA, those who took a cooking class on Mediterranean-style foods (and ate that way for 2 months) had less joint pain and morning stiffness and better overall health compared to those who didn’t take the class.
