A new analysis suggests that a deficiency in omega-3 fatty acids could increase the risk of heart disease, cognitive decline, inflammation, and vision problems, yet more than three-quarters of the global population are not meeting recommended intake levels.
Published in Nutrition Research Reviews, the study analyzed omega-3 consumption across countries and age groups, finding that 76% of people worldwide fall short of recommended levels of two key omega-3 fats—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—which are crucial for heart health. Experts recommend adults consume at least 250 milligrams of EPA and DHA daily, but intake is significantly lower in many regions.
Michelle Routhenstein, a New York–based preventive cardiology dietitian at Entirely Nourished, told Fox News Digital that low omega-3 levels can negatively affect heart health, cognitive function, and inflammation, increasing the risk of heart attacks and sudden cardiac death.
She highlighted oily fish such as salmon, mackerel, sardines, herring, trout, and anchovies as the richest dietary sources of EPA and DHA.
“Levels around 8% are associated with lower cardiovascular risk, while levels below approximately 4% are considered low,” Routhenstein explained.
