Omega-3s Linked to Longer Lifespan

Omega-3s have been linked with a host of individual health benefits, ranging from heart health to better immunity. Now, for the first time ever, a study has found that people with higher blood levels of omega-3s may actually live up to 2.2 years longer than those with lower blood levels.

Participants in the study included 2,700 Americans who were 65 or older at the start of the Cardiovascular Health Study (CHS). Data for that study was collected over the course of 16 years.

The researchers measured levels of three types of omega-3 fatty acids in the participant’s blood: DHA, EPA and DPA. They found that higher DHA levels were correlated with a 40% lower risk of coronary heart disease (CHD). The reduction in risk rose to 45% when looking only at CHD death due to electrical disturbances of the heart rhythm (arrhythmias).

They also noted that EPA was more strongly associated with a lower risk of a nonfatal heart attack and DPA was linked with a lower risk of death by stroke.

The participants with the highest levels of all three omega-3s had a 27% lower risk of total mortality overall.

Researchers at the Harvard School of Public Health conducted the study. It was published on April 2, 2013, in Annals of Internal Medicine.

Omega-3s have been linked to a number of health benefits, including improved brain health, alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s, while ALA omega-3 fatty-acids are plant derived and can be found in flaxseed oil, vegetable oil, and walnuts.
