Fish oil is renowned for its numerous health benefits, primarily attributed to its rich content of omega-3 fatty acids, specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These essential fatty acids play crucial roles in promoting cardiovascular health by reducing triglyceride levels, lowering blood pressure, and decreasing the risk of heart disease and stroke.
Consuming higher levels of omega-3 fatty acids (EPA/DHA) has been shown to have a protective role against cardiovascular disease (CVD), but the role of EPA/DHA in modifying CVD risk associated with a family history of CVD is unknown.
What the study showed: This study pooled the results from 15 observational studies (for a total of >40,000 adults without CVD), analyzed blood levels of EPA/DHA, and collected family history of CVD. The authors report a significant interaction between low EPA/DHA and family history of CVD, in which low EPA/DHA plus a family history was associated with a relative risk of 1.41 (95% CI: 1.30–1.54), higher than for either low EPA/DHA (RR=1.06; 95% CI: 0.98–1.14) or family history of CVD (RR=1.25; 95% CI: 1.16–1.33) alone.
CONCLUSIONS:
A significant interaction between biomarkers of low EPA/DHA intake, but not the other PUFA, and a family history was observed. This novel finding might suggest a need to emphasize the benefit of consuming oily fish for individuals with a family history of CVD.
Put differently, these findings suggest that EPA/DHA offers enhanced protection for individuals with a family history of cardiovascular disease (CVD) compared to the general population. This underscores the importance of prioritizing the consumption of fish oil (EPA/DHA) as a significant strategy for reducing the risk of CVD in patients with a family history of the condition.
If you don’t consume lots of cold-water fish or other food that contain high levels of EPA/DHA, a great source of EPA/DHA is from Standard Process.
