Many fatty fish like salmon, mackerel and herring also contain these valuable oils. Omega-3s convert in the body into hormone-like substances that decrease inflammation and pain. Fish oil is an anti-inflammatory agent. Fish oil acts directly on the immune system by suppressing 40 to 55 percent of the release of cytokines, compounds known to destroy joints. Many other studies also demonstrate that eating moderate amounts of fish or taking fish oil reduces pain and inflammation, particularly for arthritis sufferers.

Preliminary studies suggest that omega-3s may help quell the aches and pains of rheumatoid arthritis. And that’s no surprise, since omega-3s are touted for their ability to reduce inflammation. In addition to soothing aching joints, omega-3s can also tame your troubled tummy (especially when caused by stress) according to a 2005 Scandinavian Journal of Nutrition study.
