76% of the world isn’t getting enough Omega-3, raising risks for mood, memory and immunity, says study 

A recent review shows that 76% of the world isn’t getting enough omega-3, key fats linked to heart, brain, mood and lifelong health. Researchers say food alone isn’t enough for most people and clearer, worldwide guidelines are urgently needed.

It’s not often that nutrition research comes up with a finding so clear, and so worrying. But the latest global review from the University of East Anglia, University of Southampton and Holland & Barrett has done exactly that. According to the report, more than three-quarters of the world isn’t getting the omega-3 it needs, not even close. And this gap, scientists warn, is shaping our long-term health.

The review, the first of its kind to examine omega-3 recommendations across every life stage, found that 76 percent of people fall short of advised intake levels of EPA and DHA, the long-chain fatty acids that support everything from heart health and immunity to mood and memory. “We found big gaps between what’s advised and what most of us consume,” said Prof Anne Marie Minihane from UEA’s Norwich Medical School. She stresses that closing this gap will require “easier, sustainable ways to get these important nutrients, like foods enriched with omega-3s or supplements.”

Omega-3s support brain development in babies, reduce the chances of pre-term birth, strengthen immunity, protect the heart, and are linked to lower risks of depression and cognitive decline later in life. “The health benefits of EPA and DHA are too important to ignore,” said Dr Abbie Cawood, Science Director at Holland and Barrett. But meeting recommended levels through food alone is proving much harder than expected, especially for those who rarely eat oily fish.

This challenge is especially clear in parts of Asia, India and Latin America, where fish consumption is lower or access to supplements is limited. Even in regions with strong nutrition awareness, inconsistent guidelines make it difficult for the public to know what “enough” actually means. Prof Philip Calder from the University of Southampton explains: “What is clear is that most people are not meeting these recommendations.”

Why you need Omega-3

Recommended intake levels are clearer than ever: Most adults need 250 mg of EPA + DHA a day, while pregnant women need an extra 100–200 mg of DHA.
