While “omega-3” is often used as a catch-all term, the fatty acids that fall under that omega-3 umbrella have varying and unique benefits, as we’ve discussed in our recent overview of the 6 key omega-3 fatty acids. However, recent research indicates that most of the omega-3s have at least one thing in common: they support good heart health.

In a study published last year in the journal Nutrients, “Circulating Omega-3 Polyunsaturated Fatty Acids Levels in Coronary Heart Disease: Pooled Analysis of 36 Observational Studies,” researchers analyzed fatty acid and heart health data from 36 studies of nearly 29,000 people, conducted in 11 countries.

Their analysis found that higher levels of the omega-3s DHA, EPA, ALA, and DPA were all associated with lower rates of cardiovascular heart disease:

• DHA: 25% reduced risk
• DPA: 20% reduced risk
• EPA: 17% reduced risk
• ALA: 11% reduced risk

The study also found that higher overall levels of omega-3s were associated with a 20% reduction in the risk of cardiovascular heart disease, and that people with cardiovascular disease had lower levels of DHA, EPA, and DPA. In addition, they found that higher DHA and EPA levels correlated with lower likelihood of both non-fatal and fatal cardiovascular heart disease.

The study’s authors credited these risk reductions to omega-3 fatty acids’ widely recognized roles in reducing and regulating blood lipid levels, blood pressure regulation, and mediating inflammation and oxidation.

This study is just one of countless studies published in recent years connecting improved dietary levels of omega-3s with good heart health, and we look forward to elevating and exploring ongoing research into how omega-3 fatty acids complement heart health and lifelong wellness.
