A new study finds that eating a weekly portion of salmon or other fatty fish, such as trout or mackerel, could reduce your risk of developing rheumatoid arthritis by more than half.

In a study published Monday in the Annals of Rheumatic Diseases, the Karolinska Institute in Stockholm found that the omega-3 fatty acids in fish can cut the risk of chronic inflammatory disease by 52 per cent.

Prior research from 2009 suggests that consuming fish oils could help reduce inflammation that leads to a variety of diseases, including rheumatoid arthritis. In this study, researchers highlighted the benefit to long-chain omega-3 polyunsaturated fatty acid (Pufa) content in fish.

If you prefer lean fish, such as cod or canned tuna, the same benefit could be found in eating four servings a week, the researchers found. Long-term, weekly consumption of any type of fish was associated with a 29 per cent lower risk of the disease.

However you'll need to sustain a regular diet of fish for at least 10 years to enjoy the health prevention against the condition, they added.

To reach their findings, head researcher Alicja Wolk and her team analyzed the diets of 32,232 Swedish born between 1914 and 1948. Subjects completed questionnaires about their food intake and lifestyle in 1987 and 1997. Women who consumed at least 0.21g of omega-3 Pufas daily had the 52 per cent reduced risk, the study found.
