Omega-3s May Help Rheumatoid Arthritis
Omega-3 fatty acid-rich fish oil supplements may provide modest improvement in rheumatoid arthritis (RA), according to a double-blind, placebo-controlled study conducted at the University of Newcastle in Australia. In this study, 50 people with RA were randomly assigned to take either 40 mg/kg body weight of fish oil (containing 60 percent omega-3 fatty acids) or placebo daily for 15 weeks. The fish oil group had an average age of 54 and an average disease duration of 12 years, whereas the placebo group was 60 years old on average and had RA for an average of 15 years. Because omega-6 fatty acids, found in most vegetable oils, compete with omega-3 fatty acids, the researchers included only subjects who generally ate less than 10 g/day of omega-6 fatty acids.
