A recent study published in Nutrition Research Reviews warns that more than three-quarters of the global population is not consuming enough omega-3 fatty acids, which may increase the risk of heart disease, cognitive decline, inflammation, and vision problems. Researchers from the University of East Anglia, the University of Southampton, and Holland & Barrett analyzed omega-3 intake patterns across various countries and age groups, discovering that 76% of people worldwide fall short of the recommended levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential for heart health.
Most adults should aim for at least 250 milligrams of EPA and DHA per day. However, actual intake is significantly lower in many regions. Low omega-3 levels can lead to increased risks of heart attacks, sudden cardiac death, higher triglycerides, irregular heart rhythms, and plaque in the arteries. Additionally, inadequate omega-3 intake is linked to faster cognitive decline, a higher risk of Alzheimer's disease, increased rates of depression, and worsened inflammation in autoimmune conditions like psoriasis.
Michelle Routhenstein, a preventive cardiology dietitian, emphasized the importance of understanding omega-3 needs and sources. "The richest dietary sources of EPA and DHA are oily fish, such as salmon, mackerel, sardines, herring, trout, and anchovies," she explained to Fox News. For those who do not consume fish regularly, supplements can help raise EPA and DHA to healthier levels.
To ensure adequate omega-3 intake, testing omega-3 levels through a blood test, known as the omega-3 index, can help determine if intake is sufficient. Levels around 8% are associated with lower cardiovascular risk, while levels below 4% are considered low.
