Daily Omega-3 Fatty Acid Intake Recommendations
Adequate Intake of Alpha-Linolenic Acid (ALA)
The National Health and Nutrition Examination Survey (NHANES) 2017-2018 data indicates that American adults consume approximately 1.98 grams per day of alpha-linolenic acid (ALA), meeting the adequate intake (AI) values of 1.1 grams per day for females and 1.6 grams per day for males. This suggests that the general population is achieving the recommended levels of ALA, which is a plant-based omega-3 fatty acid.
Recommended Intake of Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA)
In contrast to ALA, the intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) among American adults is significantly lower than recommended. The NHANES data shows that the average consumption is about 35 milligrams per day of EPA and 76 milligrams per day of DHA. The American Heart Association (AHA) recommends consuming oily fish at least twice per week, which equates to approximately 500 milligrams per day of EPA plus DHA . For individuals with documented cardiovascular disease, the recommendation is even higher, at about 1 gram per day of EPA plus DHA .
Global and National Recommendations
International guidelines generally recommend an intake of 250 to 500 milligrams per day of EPA and DHA for cardiovascular health . This aligns with the AHA's recommendation and is supported by multiple studies indicating that such levels are associated with a reduced risk of coronary heart disease (CHD). For patients with hypertriglyceridemia, the recommended intake can be as high as 4 grams per day.
Omega-3 Supplementation and Cognitive Benefits
Research also suggests that omega-3 supplementation, particularly with a daily dose of at least 450 milligrams of DHA and EPA, can improve cognitive function in children and adolescents. This indicates that the benefits of omega-3 fatty acids extend beyond cardiovascular health.
Practical Recommendations for Increasing Omega-3 Intake
Given the low intake of EPA and DHA from food sources alone, supplementation may be necessary for many individuals to meet the recommended levels. Incorporating fish into the diet, such as consuming mussels three times per week, has been shown to significantly improve omega-3 status. Additionally, fortified foods and omega-3 supplements are practical alternatives to help achieve the necessary intake levels .
Conclusion
While American adults generally meet the recommended intake for ALA, they fall short of the guidelines for EPA and DHA. To achieve the recommended levels of these essential fatty acids, a combination of dietary changes, such as increased fish consumption, and supplementation may be necessary. This approach can help reduce the risk of cardiovascular disease and potentially improve cognitive function.
