Omega-3 deficiency is now a global public health problem. A new review from the University of East Anglia, Holland & Barrett, and the University of Southampton shows a massive intake gap. Seventy-six percent of the world’s population fails to meet recommended omega-3 levels.
Let’s break down what the research found and why it matters.
This is the first-ever global review of omega-3 intake recommendations across all life stages. The findings are clear.
• 76% of people worldwide are not meeting recommended EPA and DHA levels.
• Intake guidelines vary widely between countries.
• Most adults need 250 mg of EPA + DHA daily.
• Pregnant women need an additional 100–200 mg of DHA.
Prof Anne Marie Minihane puts it simply: There’s a wide gap between what people should consume and what they actually eat.
Omega-3 intake supports health from infancy to old age.
Here are the standout benefits:
• Lower risk of pre-term birth.
• Better visual and cognitive development in infants.
• Improved heart health in adults.
• Stronger immune function.
• Reduced risk of depression and cognitive decline, including Alzheimer’s disease.
Yet most people don’t get enough because they eat limited seafood, lack awareness, or face sustainability issues.
The review highlights a major disconnect:
• Evidence is strong.
• Public guidelines differ by country.
• Actual intake levels remain too low.
This patchwork of recommendations confuses both consumers and clinicians. The authors hope the review will guide countries, especially in Asia and Latin America, to develop clear, evidence-based public health policies.
The review recommends simple changes:
• Eat more oily fish like salmon, mackerel, or sardines.
• Use omega-3 fortified foods when possible.
• Consider supplements if dietary intake is low.
These options can help bridge the gap for populations with limited seafood access or sustainability concerns.
Omega-3 deficiency isn’t just a nutritional issue. It reflects a global need for clearer guidance, smarter food policies, and better public awareness. The authors hope their work will shape future recommendations and make omega-3 intake achievable for everyone.
