Foods to avoid with Rheumatoid Arthritis (RA)
For rheumatoid arthritis, guidance focuses on fat quality and inflammatory load rather than a single trigger. Trans fats, hydrogenated oils and high-sugar sweeteners are the most consistently flagged, while omega-3 rich fish and whole foods tend to be favoured for joint inflammation.
