Scientific research continues to examine all the possible benefits of fish oil. What has been demonstrated time and again in studies are the beneficial properties of fish oil regarding its antioxidant properties and the protection afforded your heart against conditions such as high triglyceride levels and plaque build-up in arteries. Fish oil supplementation is recommended by a variety of health experts for many conditions.
Background
Essential fatty acids are separated into two groups: omega-3 fatty acids and omega-6 fatty acids. Fish oil has high levels of two of these fatty acids, referred to as DHA and EPA. These two fatty acids have been determined through research to provide the known benefits of fish oil.
Considerations
The American Heart Association, or AHA, advises that omega-3 fatty acids are of benefit both to those with healthy hearts and those who have or are at-risk for cardiovascular disease.
An important component of a heart-healthy diet, as recommended by the AHA, is to eat at least two portions of fish each week. The American Heart Association further advises that obtaining omega-3 through diet is the preferred method, but those with coronary artery disease or high triglyceride levels should consult their health-care provider to discuss fish oil supplements.
Expert Insight
Fish oil supplementation is also recommended for those with chronic diseases such as diabetes, rheumatoid arthritis and Crohn's disease, advises Tanya Edwards, M.D., Director of the Center for Integrative Medicine at the Cleveland Clinic. Dr. Edwards explains that the antioxidant properties of fish oil help to eliminate inflammation in the body that is caused by free radicals. Edwards states, "Every disease has inflammation as part of its process -- even heart attacks." With the use of fish oil supplements, she adds, "many age related diseases brought on by inflammation become less inevitable."
Recommendations
The Heart Center of the Rockies agrees with the American Heart Association's recommendations for fish oil supplementation: People with currently diagnosed coronary heart disease should get at least 1 gram daily of DHA and EPA, preferably from dietary sources, but supplementation may be desired; people with currently diagnosed elevated triglycerides should get 2 to 4 grams daily of DHA and EPA using fish oil supplements.
Both the AHA and the Heart Center advise that you consult your physician before beginning supplementation.
Features
Not all fish oil supplements are equal. Dr. Edwards advises that you "look for the highest levels of docosahexaenoic acid (DHA) and eicosapentenoic acid (EPA). The combined amount of DHA and EPA should make up more than 50 percent of the total milligrams of the dosage."
