Heralded for its heart-healthy actions, fish oils offer high concentrations of polyunsaturated fats called omega-3-fatty acids. While all fish contain these fats, cold-water fish--salmon, sea bass, tuna, trout, mackerel--are particularly rich sources because of their diet: plankton packed with omega-3s. Interestingly, the colder the water, the more omega-3s in the plankton. Cold-water fish also boast the most potent forms of omega-3s: the essential fatty acids known as eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA). Consumed as part of a fish-filled diet or in supplement form, omega-3s have myriad healing powers.
Health Benefits
Scientists are constantly discovering new health benefits for fish oils and their essential fatty acids (EFAs, including omega-3s). In addition to their more notable properties as heart-healing substances, there's evidence that these fatty acids ease menstrual cramps and the pain and heavy bleeding of endometriosis. Omega-3s may even aid mental disorders such as schizophrenia. Preliminary findings in people with manic depression (bipolar disorder) link fish oil supplementation to fewer mood swings. Some experts even contend that the rising tide of depression in the United States can be traced to the increasingly fish-poor diet people tend to follow.
Specifically, fish oils may help to:
Prevent and treat cardiovascular disease, including complications of high blood pressure. Several years ago scientists discovered why Greenland Eskimos suffer little heart disease despite their high-fat diets: They eat a lot of cold water fish. Closer examination revealed that it was the omega-3s in the fish that were protecting the hearts of these far-north inhabitants. Subsequent research revealed that the omega-3s discourage platelets in the blood from clumping together, reducing the risk that blood will clot and cause a heart attack. The omega-3s also ease strain on the heart and reduce the risk for angina (chest pain) by, among other things, reducing high blood pressure, keeping arteries flexible (they control inflammation within artery walls), lowering LDL ("bad") cholesterol and triglycerides (blood fats), and possibly even raising HDL ("good") cholesterol. Now there's evidence that omega-3s can prevent heart-rhythm abnormalities (arrhythmias). In a large, recently published Lancet study, fish oil supplements (1 gram a day) significantly reduced the incidence of arrhythmias in heart attack survivors. There were many fewer deaths (and deaths from heart problems specifically) as a result.
Prevent certain cancers. Anticancer actions have been identified in omega-3s, with some recent studies reporting that even small amounts of fish (as part of the diet) can reduce the risk for colon, breast, prostate, and other cancers.
Treat rheumatoid arthritis. Joint stiffness and swelling caused by this painful condition may lessen because of the inflammation-fighting actions of omega-3s. Some sufferers find that they can even get by with lower doses of conventional medications. In one recent study, participants taking fish oil supplements daily for 12 weeks or more noticed that they were experiencing less morning stiffness and had fewer tender joints. Improvements increased even more after 18 to 24 weeks of taking fish oil supplements, with the benefit lingering for up to 8 weeks after the supplements were stopped.
Control diabetes. Nerve problems and heart disease are complications of this chronic condition. Fish oils may help by preventing nerve damage and possibly raising HDL ("good") cholesterol. On a basic, cellular level they may also improve the body's metabolic use of its own insulin.
Ease symptoms of lupus, psoriasis and eczema. In people with lupus, omega-3s appear to control inflammation in the joints, skin, kidneys, and other body tissues. Those suffering from psoriasis or eczema may find that the angry, itchy patches common to these ailments respond to treatment with fish oils after about a month. Interestingly, research indicates that psoriasis sufferers tend to have low levels of omega-3s.
Minimize Crohn's disease symptoms. This often painful bowel condition tends to flare up and then subside in cycles over time. When taken long term for preventive purposes, the essential fatty acids in fish oils will keep inflammation in the digestive tract under control. In a recent Italian study, fish oil supplements (about 3 grams in enteric-coated form a day) significantly reduced the number of flare-ups in Crohn's disease sufferers. All of the study participants were initially in remission but had signs of inflammation. By the end of the study, nearly 70% of the participants given a placebo had a relapse while only about 30% of those taking the fish oils capsules did.
Delay the onset of Raynaud's disease symptoms. Omega-3s inhibit inflammation within vessels, making fish oils potentially useful in stalling the numbness, tingling, and other symptoms resulting from exposure to cold air. One placebo-controlled study of 32 Raynaud's sufferers found that fish oil supplements slowed the appearance of such bothersome symptoms by an average of 15 minutes (often enough time to allow sufferers to avoid painful symptoms by getting to a warm place).
Note: Fish oils have also been found to be useful for a number of other disorders. For information on these additional ailments, see our Dosage Recommendations Chart for Fish Oils
