Eat Fish to Reduce Inflammation

If you have joint pain from rheumatoid arthritis (RA), eat more fish.

 Fatty coldwater fish like salmon and mackerel are good sources of omega-3 fatty acids. 

Omega-3s may help keep your joints healthy, as well as reduce inflammation, a cause of joint pain and tenderness in people with RA.

 Don't like fish? Try fish oil capsules instead.
