Omega-3s and heart health

Published: 30-Jan-2017

With heart disease being the leading cause of death in the US, it’s time to listen to your heart according to the Centers for Disease Control and Prevention

As part of a healthy lifestyle that includes exercising, getting enough sleep, not smoking and having a healthy diet, omega-3s – and specifically EPA and DHA – may help maintain healthy blood pressure, support healthy triglyceride levels and manage risk of heart disease.

Omega-3s at work in the heart

The omega-3s EPA and DHA found in fatty fish and omega-3 dietary supplements help to maintain healthy blood vessels and may help reduce chronic inflammation throughout the body.

This inflammation can damage your blood vessels and potentially lead to heart disease.

With more than 2000 studies conducted on omega-3s and heart health, the totality of evidence suggests that there is a positive correlation between increased omega-3 intake and heart health benefits.

Omega-3s and blood pressure

Emerging research has shown important vascular effects of omega-3s, including a reduction in blood pressure, increased dilation of the coronary arteries and improved function of the (endothelial) cells that line the inner surface of the blood vessels.

Omega-3s and triglycerides

One of the most important and consistent effects of EPA and DHA is evident in their role in reducing blood triglyceride levels as high triglycerides are a risk factor for cardiovascular disease.

The triglyceride-lowering effect of omega-3s is observed in individuals with normal blood lipid levels, but is even more dramatic in those with elevated triglycerides.

For example, a study published in the American Journal of Clinical Nutrition found that high-doses of EPA and DHA omega-3s (3000 mg per day) compared to placebo may help lower blood triglyceride levels.

Omega-3s and cardiovascular events

EPA and DHA omega-3s are integral as structural components of cells within your heart and we are still learning about all of their heart health benefits.

Unfortunately, most people do not get enough EPA and DHA omega-3s in their daily diet. A scientific paper published in PLoSMed (Public Library of Science)  estimated that in 2005 between 72 and 96 thousand people – in the U.S. alone – died from cardiovascular events due to insufficient intake of omega-3s.

Cardiovascular events are characterised by any incident that may cause damage to the heart muscle.
