Studies have shown that omega-3 fatty acids in fish oil have an anti-inflammatory property and can relieve tender joints and ease morning stiffness. The best source is found in cold-water fish such as herring, mackerel, trout, salmon and tuna. A serving size of 3 ½ ounces of fish contain about one gram omega-3 fatty acids.
If you choose to try fish oil supplements, talk to your doctor about dosage. People with RA can often take a higher level of fish oil than is recommended for the general public, but there can be side effects. Higher doses of fish oil may interact with certain drugs, including those for high blood pressure.
Increasing your intake of fiber from fruits, vegetables and whole grains may also help reduce inflammation. Studies show that adding fiber to the diet results in lower levels of C-reactive protein (CRP) in the blood; CRP is an indicator of inflammation.
Extra-virgin olive oil may contain a compound called oleocanthal that blocks the enzymes that cause inflammation. But, it would take 3 ½ tablespoons of olive oil – 400 calories worth – to equal the anti- inflammatory properties of one 200-mg ibuprofen tablet. Instead, use the oil as an alternative to other cooking oils and butter.
