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 study published in the American Journal of Clinical Nutrition, researchers investigated whether potato consumption (including fried and unfried potatoes) is associated with increased premature mortality risk. The study included 4440 participants with an 8-year follow-up from the Osteoarthritis Initiative cohort study. During the 8-year follow-up, 236 participants died. The results showed that participants who consumed fried potatoes 2–3 times per week and ≥3 times per week were at an increased risk of mortality. The consumption of unfried potatoes was not associated with an increased mortality risk.
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.
