The omega-3 fatty acids eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA, are referred to as essential fatty acids, since they must be obtained through diet or supplementation. Omega-3 fatty acids are associated with several benefits, including reducing inflammation and better nervous system function. In addition, research indicates that omega-3 fatty acids might also improve heart health.
Cardiovascular Disease
Researchers from Columbia University in New York reviewed the literature regarding the relationship between omega-3 consumption and cardiovascular disease. They reported in the July 2006 issue of the "American Journal of Clinical Nutrition" that subjects consuming omega-3 supplements EPA and DHA experienced a decrease in all causes of mortality, cardiac death and sudden death.
Triglycerides
Scientists from the University of California Davis, Veterans Affairs Northern California Health Care System and U.S. Department of Agriculture studied the impact of DHA on high triglyceride levels in men, a risk factor for artery hardening. At the end of the study, which was published in the August 2007 issue of the "American Journal of Clinical Nutrition," researchers found that patients consuming 3 g of DHA per day for 45 days lowered their triglycerides compared to those receiving a placebo.
Arteries
In research reported in the March 2010 issue of the journal "Clinical Nutrition," scientists from the University of Reading in the United Kingdom examined the impact of EPA and DHA on arterial stiffness after a medium fat meal. They discovered that healthy women and men consuming 4.7 g of EPA and DHA experienced less arterial stiffness after the meal compared to those with a placebo. Keeping arteries healthy allows for the maximum amount of oxygen and blood to reach the heart, which boosts heart health.
Side Effects and Interactions
Although omega-3 fatty acids might have heart benefits, side effects have been reported, including bloating, stomach upset and diarrhea. Furthermore, omega-3s may interact with certain medications such as blood thinners and cholesterol-lowering medications. Consult your health care provider before consuming omega-3 fatty acids.
