Olive Oil Added To Fish Oil Works Better For Rheumatoid Arthritis

Olive oil can significantly benefit rheumatoid arthritis (RA) patients who are already taking fish oil supplements, according to a study conducted in Brazil.

RA is an inflammatory condition caused by an autoimmune reaction that targets the joints; symptoms include joint pain, stiffness, swelling and fatigue. Supplementing with fish oil has demonstrated a positive effect on RA symptoms. Fish oil contains high amounts of two fatty acids EPA and DHA, polyunsaturated omega-3 fatty acids that have been shown to have anti-inflammatory properties. Olive oil is rich in the monounsaturated fatty acid oleic acid, which is also believed to have anti-inflammatory properties. Also, extra-virgin olive oil contains vitamin E and numerous other compounds that act as antioxidants and could contribute to its beneficial effects.

In the study, 43 patients with RA were randomly assigned to one of three groups: one group received a total of 3,000 mg of omega-3 fatty acids from 20 capsules of fish oil per day; a second group received the same amount of fish oil fatty acids, plus 6.8 grams (about two teaspoons) of extra virgin olive oil per day, taken on salads; and a third group received a soy oil placebo. Symptoms (pain, stiffness and fatigue) and ability to function (hand grip strength and limitations to daily activities and self-care) were evaluated at clinic visits at the beginning of the study, after 12 weeks and after 24 weeks.

At the end of the study, both groups supplementing with oils experienced significantly more improvement than the placebo group. The improvements noted at 12 weeks, however, were seen more in people using fish oil, plus olive oil than those using just fish oil. Furthermore, those using fish oil and olive oil had a significantly greater improvement in a blood marker of RA than those using placebo, but those using fish oil alone did not.

Results of the study suggest that extra-virgin olive oil might enhance the benefits of fish oil in people with RA.
