Study Reveals Omega-3 Deficiency Raises Heart Disease Risk Globally

A recent analysis highlights a significant global health concern, revealing that more than three-quarters of the global population falls short of the recommended intake of omega-3 fatty acids. This deficiency may increase the risk of heart disease, cognitive decline, inflammation, and vision problems. The findings come from a comprehensive study published in *Nutrition Research Reviews*, conducted by researchers from the University of East Anglia, the University of Southampton, and Holland & Barrett.

The review indicates that approximately 76% of people worldwide do not meet the advised levels of two essential omega-3 fats critical for heart health: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Global health authorities recommend that adults should aim for at least 250 milligrams of these fatty acids daily, yet actual consumption falls significantly short in various regions.

Health Implications of Low Omega-3 Intake

According to Dr. Mike Varshavski, a physician featured on *Fox & Friends*, the importance of visiting healthcare providers cannot be overstated, particularly concerning nutrient deficiencies. To gain insight into the health implications of low omega-3 intake, *Fox News Digital* consulted Michelle Routhenstein, a preventive cardiology dietitian based in New York.

Routhenstein emphasized that inadequate levels of omega-3 fatty acids can have detrimental effects on heart health and cognitive function. She noted that low omega-3 intake is associated with an increased risk of heart attacks and sudden cardiac death. Additionally, insufficient omega-3 levels can lead to elevated triglycerides, irregular heart rhythms, and arterial plaque buildup.

Moreover, the impact extends beyond cardiovascular health. Research has linked low omega-3 intake to faster cognitive decline, heightened risks of Alzheimer’s disease, and increased rates of depression. Routhenstein highlighted that low levels may aggravate inflammation in autoimmune conditions, such as psoriasis, and can adversely affect eye health, as omega-3s play a vital structural role in the retina.

Boosting Omega-3 Levels Through Diet and Supplements

To improve omega-3 levels, Routhenstein recommends understanding dietary needs and identifying rich sources. She stated, “The richest dietary sources of EPA and DHA are oily fish, such as salmon, mackerel, sardines, herring, trout, and anchovies.” For optimal health, individuals should aim to consume oily fish three to four times per week.

For those who do not regularly eat fish, supplements can be an effective alternative to raise EPA and DHA levels. Routhenstein advises that the dosage of omega-3 supplements should be tailored to individual needs based on lab results, medications, and overall medical history. Generally, moderate, quality-controlled supplements are considered safe for most individuals.

There is also evidence supporting the use of prescription-strength omega-3 products. Routhenstein pointed out that “High-dose EPA, such as 4 grams per day of icosapent ethyl, has been shown to reduce major cardiovascular events in certain high-risk populations, while similar doses of mixed EPA/DHA have not consistently shown the same benefit.”

Monitoring omega-3 levels can provide valuable insights into dietary adequacy. The omega-3 index, a blood test that measures EPA and DHA in red blood cells, is recognized as a reliable method for assessing omega-3 status. Routhenstein noted, “Levels around 8% are associated with lower cardiovascular risk, while levels below approximately 4% are considered low.”

Individuals uncertain about their omega-3 status or whether supplementation is appropriate should consult healthcare providers to develop a personalized approach to diet and supplementation.

As awareness of omega-3 deficiencies grows, addressing this nutrient gap is essential for improving heart health and overall well-being for millions worldwide.
