Essential fatty acids

Encyclopedia of Alternative Medicine, Apr 06, 2001 by Douglas Dupler

EFA supplementation is recommended for over 60 health conditions. EFAs are used therapeutically to treat and to prevent cardiovascular problems, including heart disease, high cholesterol, strokes, and high blood pressure. EFAs also have anti-inflammatory effects in the body, and are used in the nutritional treatment of arthritis, asthma, allergies, and skin conditions (e.g., eczema). EFAs are used as support for immune system disorders including AIDS, multiple sclerosis , lupus, and cancer.

Other conditions that may improve with EFA supplementation include acne and other skin problems, diabetes, depression, menopausal problems, nervous conditions, obesity, memory and learning disabilities, eye problems, and digestive disorders. EFAs are recommended for weight loss programs, as they may assist fat metabolism in the body. EFA supplementation is a recommended preventative practice, as well.

Common EFA supplements are flaxseed oil, evening primrose oil , borage oil , black currant seed oil , hemp seed oil, and cod liver oil. Consumers should search for supplements that contain both omega-3 and omega-6 EFAs, because imbalances of EFAs may occur if either is taken in excess over long periods of time. Flaxseed oil is a recommended supplement, because it contains the highest percentage of omega-3 fatty acids with some omega-6 EFAs, as well. Flaxseed oil is generally the least expensive source of omega-3 EFAs as well, generally much cheaper than fish oil supplements. Evening primrose oil is a popular supplement as well, because the GLA it contains has shown benefits in treating premenstrual syndrome and other conditions. However, evening primrose oil contains no omega-3 EFAs. Hemp seed oil is a well-balanced source of both EFAs.

Supplements are available from health food stores in liquid and capsule form. The recommended daily dosage is one to two tablespoons (13-26 capsules), taken with meals. EFAs can also be obtained from a diet that includes cold-water fish consumed twice per week, whole grains, dark green leafy vegetables, walnuts, pumpkin seeds, wheat germ , soy products, canola oil, and other foods mentioned above. Whole flaxseeds are a wholesome source of EFAs as well, and can be freshly ground and added to salads and other dishes.

EFA supplements are generally fragile products, and must be produced, packaged and handled properly. Consumers should search for quality EFA supplements produced by reputable manufacturers. Products that are organically grown and certified by a third party are recommended. EFA products should be produced by "cold or modified expeller pressing," which means that they were produced without damaging temperatures or pressure. Products should be packaged in light-resistant containers, because sunlight damages EFAs. Packages should include manufacturing and use-by dates on them, in order to assure freshness. Stores and consumers should keep EFA products under refrigeration, because heat damages them, as well. Taste can indicate the quality of EFA oils: those that have no flavor usually are overly refined, and those that taste bitter are old or spoiled. Because of their low temperature threshold, nearly all the oils that are used as EFA supplements are not suitable for use as cooking oils.
