Fish oil has been touted as a remedy for a number of conditions.
Data from at least a few randomized double-controlled studies have demonstrated a beneficial effect of dietary fish oil in rheumatoid arthritis In fact, more than nine studies overall have shown statistically significant reductions in the number of tender joints. In many of these studies, patients were able to lower the amount of non steroidal anti-inflammatory medications and corticosteroids. One study suggested that combining fish oil with olive oil may enhance the anti-inflammatory effects of fish oil. (Kremer J, et al Dietary fish oil and olive oil supplementation in patients with rheumatoid arthritis. Clinical and immunologic effects. Arthritis Rheum 1990; 33:810-820).
\"fish Oil\"
Fish oil works by reducing inflammation. Scant evidence indicates it may retard progression of rheumatoid arthritis... although the effect, if it exists, is relatively mild.
Fish oil is a great source of omega-3 fatty acids which can reduce inflammation. Fish oil also lowers triglycerides and reduces blood pressure therefore protecting against cardiovascular disease as well. This is noteworthy because of the known increase in cardiovascular risk, patients with rheumatoid arthritis have.
It is difficult to get therapeutic amounts of fish oil by eating fish alone. Supplements are advised.
The type of fish oil is important. The oil should be derived from cold-water fish such salmon, cod, mackerel, halibut, tuna, and herring.
Fish oil comes in a variety of preparations. The most common is gel caps. Each gel cap should contain at least thirty per cent EPA/DHA, which are the active compounds. For rheumatoid arthritis about 2.6 grams of fish oil containing 1.6 grams of EPA should be taken twice a day.
A few words of caution. Patients on anticoagulant therapy with warfarin may notice their clotting times will bounce around. Pregnant woman may want to avoid eating cold water fish because of the danger of mercury toxicity. On a lighter note, burps often have a fishy taste and odor.
