Global Omega-3 Deficiency Heightens Heart Disease Risks, Study Finds

A recent analysis highlights a concerning trend: over three-quarters of the global population is not consuming adequate levels of omega-3 fatty acids, which may significantly increase the risk of heart disease and other health issues. This information comes from a review published in Nutrition Research Reviews, conducted by researchers from the University of East Anglia, the University of Southampton, and Holland & Barrett.

The study reveals that approximately 76% of individuals worldwide fail to meet the recommended daily intake of two crucial omega-3 fats—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Global health authorities advise adults to aim for at least 250 milligrams of these essential nutrients each day. However, the actual consumption rates are alarmingly low across various regions.

To further understand the implications of this nutrient deficiency, Fox News Digital consulted with Michelle Routhenstein, a preventive cardiology dietitian based in New York at Entirely Nourished. She emphasized that low levels of omega-3s can adversely affect heart health, cognitive function, and inflammation, potentially leading to increased risks of heart attacks and sudden cardiac death.

Research indicates that inadequate omega-3 intake is also associated with higher triglyceride levels, irregular heart rhythms, and plaque buildup in arteries. Moreover, insufficient omega-3s can lead to cognitive decline, a heightened risk of Alzheimer’s disease, and increased rates of depression. Routhenstein pointed out that these deficiencies may exacerbate autoimmune conditions such as psoriasis and negatively impact eye health, as omega-3s are integral to the structural integrity of the retina.

To improve omega-3 levels, Routhenstein advises individuals to consume oily fish, which are the richest dietary sources of EPA and DHA. Fish such as salmon, mackerel, sardines, herring, trout, and anchovies should ideally be included in diets three to four times per week. For those who do not regularly eat fish, omega-3 supplements may help achieve healthier levels.

When considering supplementation, Routhenstein notes that dosages should be tailored to individual health needs, including lab results and medical history. Generally, moderate, quality-controlled supplements are safe for most people. There is also evidence supporting prescription-strength omega-3 products; high-dose EPA, such as 4 grams per day of icosapent ethyl, has demonstrated a reduction in major cardiovascular events within specific high-risk populations.

To assess omega-3 levels, individuals can undergo the omega-3 index blood test, which measures EPA and DHA in red blood cells. Routhenstein explains that levels around 8% are associated with lower cardiovascular risk, while those below 4% are considered low. Understanding one’s baseline omega-3 levels can facilitate more informed dietary and supplementation choices.

Those unsure of their omega-3 status or supplementation suitability are encouraged to consult with a healthcare provider to determine the best approach for their health. This emerging evidence underscores the importance of adequate omega-3 intake in maintaining heart health and overall well-being in a significant segment of the global population.
