MedicalResearch.com: What are the main findings of the study?

Answer: Women whose long-term intake of omega 3 PUFAs exceeded 0.21 g a day, equivalent to at least one serving of fatty fish or four servings of lean fish a week, had half the risk (52% lower) of rheumatoid arthritis of women who consumed less.

MedicalResearch.com: Were any of the findings unexpected?

Answer: We expected this finding since previous studies showed an inverse association between fish consumption and rheumatoid arthritis. Moreover, the antinflammatory properties of omega3 suggested its role in the protection against RA.

MedicalResearch.com: What should clinicians and patients take away from your report?

Answer: Consumption of fish could be advised to decrease the risk of RA and also other diseases (cardiovascular diseases etc.)

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Answer: In this study we did not have data to evaluate the consumption of fish oil supplements. Therefore, future research should focus on evaluate if the consumption of fish oil supplements is protective against RA as it is the omega3 intake from diet.
