The effect of various dietary regimens and nutrient supplementation on rheumatoid arthritis (RA) has been previously explored, with the majority of the evidence supporting the beneficial effect of n-3 polyunsaturated fatty acids (PUFAs), consumed mainly as fish oil supplements. However, many capsules should be taken on a daily basis (10 - 15) in order to improve health status, increasing, thus, the high drug burden these patients may encounter; inability to comply with supplementation, as depicted in drop-out rates and adverse reactions, is also of concern. On the other hand, the so far investigation of specific dietary patterns, namely elemental or vegetarian diets, revealed similar limitations regarding inability to comply, without producing clear benefit.
