A recent study reveals that a significant portion of the global population is not consuming adequate levels of omega-3 fatty acids, which may contribute to an increased risk of heart disease and other serious health issues. According to research published in Nutrition Research Reviews, over 76% of individuals worldwide fail to meet the recommended intake of two essential omega-3 fats, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Researchers from the University of East Anglia, the University of Southampton, and Holland & Barrett conducted an analysis to assess omega-3 intake across different countries and age groups. They found that most adults should aim for a daily intake of at least 250 milligrams of EPA and DHA combined, yet actual consumption is significantly lower in many regions.
According to Dr. Mike Varshavski, a prominent physician, the low levels of omega-3 can have dire consequences for heart health. “Inadequate omega-3 levels can lead to increased risks of heart attacks, sudden cardiac death, and other cardiovascular issues,” he stated during an appearance on Fox & Friends on National Call Your Doctor Day.
To delve deeper into the implications of inadequate omega-3 intake, Fox News Digital consulted with Michelle Routhenstein, a preventive cardiology dietitian based in New York. She emphasized that low omega-3 levels are linked not only to heart health but also to cognitive function and inflammation across the body.
Research indicates that insufficient omega-3 intake may accelerate cognitive decline and elevate the risk of conditions such as Alzheimer’s disease and depression. Routhenstein added that low omega-3 levels could exacerbate inflammation in autoimmune disorders and adversely affect eye health, as omega-3s are critical to retinal structure.
Boosting Omega-3 Levels for Better Health
To improve omega-3 levels, understanding dietary sources is essential. Routhenstein highlighted that oily fish, including salmon, mackerel, sardines, herring, trout, and anchovies, are among the richest natural sources of EPA and DHA. She recommends that individuals consume oily fish three to four times a week for optimal benefits.
For those who do not include fish in their diet, omega-3 supplements can be a practical alternative. Routhenstein advised that supplementation should be tailored based on individual lab results, medications, and overall medical history. “Moderate, quality-controlled supplements are generally safe for most people,” she noted.
There is evidence supporting the effectiveness of prescription-strength omega-3 products. Routhenstein pointed out that high doses, such as 4 grams per day of icosapent ethyl, have demonstrated a reduction in major cardiovascular events among specific high-risk populations. However, similar doses of mixed EPA and DHA have not consistently shown the same benefit.
Testing omega-3 levels can provide insight into whether individuals are meeting their nutritional needs. The omega-3 index, a blood test measuring EPA and DHA levels in red blood cells, is regarded as a reliable method to assess omega-3 status. Routhenstein explained that levels around 8% are associated with lower cardiovascular risk, while levels below 4% are considered deficient.
Individuals uncertain about their omega-3 status or the appropriateness of supplementation are encouraged to consult healthcare providers to determine the best course of action. Understanding personal omega-3 levels can lead to informed dietary choices and supplementation strategies, ultimately supporting better heart health.
