Omega-3 May Help Reduce Risk of Rheumatoid Arthritis

If individuals at risk for rheumatoid arthritis (RA) consume more omega-3 fatty acids, they may be able to decrease their chance of developing the disease. Rheumatoid arthritis is a chronic inflammatory disorder that usually affects the small joints in the hands and feet. Unlike osteoarthritis, rheumatoid arthritis affects the lining of joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. Investigators analyzed selfreported data about omega-3 consumption from 30 people who had autoantibodies for rheumatoid arthritis and 47 control patients who did not. They found only 6.7% of patients who had the autoantibodies for RA were taking omega-3 supplements, compared with 34.4% in the control group. Furthermore, they found blood levels of omega-3 fatty acids to be lower in those at risk for RA. Based on the findings, researchers recommend a healthy diet that includes fish rich in omega-3 fatty acids, as well as one to three grams of fish oil a day, for those who may be at risk for RA and perhaps other inflammatory diseases.
