Why rheumatoid arthritis sufferers should start taking fish oils

Reading time: 1 minute

If you have rheumatoid arthritis (RA), start taking omega-3 fish oils.

The supplements combat atherosclerosis, or hardening of the arteries, which is common in RA sufferers.

The fish oils contain a molecule, RvT4, that boosts our body’s ability to reduce localised inflammation and remove blockages in the blood vessels, say researchers from Queen Mary University in London.

That’s especially important for people with RA as they’re twice as likely to suffer from blood vessel disease such as atherosclerosis, and that’s because they have low levels of RvT4 molecules.

In laboratory tests with mice, the researchers found that the molecules started to reverse biological processes that trigger blood vessel disease.  They ‘reprogrammed’ macrophages, a group of white blood cells, to release lipids, or blood fats, that had been blocking them from clearing away dead cells.
