Global Study Reveals Widespread Omega-3 Deficiency

A new global review has found that around 76% of people worldwide are not consuming enough omega-3 fatty acids, particularly EPA and DHA, which are essential for good health. The study, led by researchers from the University of East Anglia, the University of Southampton and Holland & Barrett, examined national and international omega-3 intake guidelines across all stages of life. It is the first review of its kind to focus on generally healthy populations.

Researchers identified a major gap between recommended intake levels and actual consumption. Omega-3s play an important role throughout life, supporting infant brain and vision development, reducing the risk of premature birth, and improving heart, immune and cognitive health in later years. Higher intake has also been linked to lower risks of depression and age-related cognitive decline.

The review highlights inconsistent guidance across countries, which adds to public confusion. Experts are calling for clearer, evidence-based recommendations and more accessible, sustainable sources of omega-3s, including fortified foods and supplements, to help populations meet daily needs.
