An international study reveals that nearly 76 percent of the world's population does not meet the recommended daily intake of omega-3 fatty acids, despite their crucial role in cardiovascular health, cognitive development, and immunity. Researchers analyzed 42 technical documents used as references for national nutritional guidelines and found that most countries recommend approximately 250 milligrams of EPA and DHA daily, with DHA supplementation during pregnancy. However, consumption data shows a massive global deficiency, leading the authors to describe it as a genuine public health gap.
A deficiency linked to low consumption of oily fish
To reach these recommended intakes, one would need to consume salmon, mackerel, sardines, or anchovies several times a week. However, in many parts of the world, access to seafood remains limited by cost, dietary habits, or cultural preferences. Plant-based sources of omega-3 fatty acids, such as flax seeds or walnuts, provide ALA, which the body converts poorly into EPA and DHA, thus preventing individuals from reaching the recommended levels. Faced with this structural difficulty, researchers believe that supplementation is often necessary, particularly for people who consume little fish and during pregnancy. Current recommendations may evolve as public health policies address this issue.
