Rheumatoid arthritis is a long-term condition that causes pain, swelling and stiffness in the joints.
Instead, you should opt for a diet rich in long-chain omega-3 polyunsaturated fatty acids, derived from fish and fish oil, the study researchers said.
This diet is associated with a reduced risk of rheumatoid arthritis, probably due to its anti-inflammatory properties, they noted.
This suggests the Mediterranean diet, which is rich in plant-based foods such as whole grains, legumes, fruit, vegetables, extra-virgin olive oil and low in red meat consumption, might have the potential to reduce the risk of rheumatoid arthritis.
