Sammanfattning
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease affecting 0,5-1% of the population. Several genetic
and environmental factors are implicated in the aetiology of RA. The only well-established environmental risk factor is tobacco
smoking. In this review we examine data linking intake of fatty acids, meat, antioxidants and vitamin D with the risk of RA.
Although there is some tendency to show a protective effect of fatty acids from fish on RA, generally, evidence on dietary risk
factors is scarce with a lack of statistical significance and reproducibility.
