In a recent study which involved 176 participants with rheumatoid arthritis (RA), those who consumed fish twice weekly had lower disease activity (number of swollen and tender joints as well as other assessments) compared with those who ate fish never to once a month.
In a recent systematic review, researchers found that omega 3 fatty acid intake is effective in reducing pain in rheumatoid arthritis patients. The analysis of 18 randomized, controlled trials showed a dose of between 3 and 6 g daily had the best effect.
