Summary
A recent study shows that over 75% of people worldwide do not consume enough omega-3 fatty acids, which are important for brain and heart health and may lower the risk of Alzheimer's disease. Omega-3s, found in oily fish and some nuts and seeds, are nutrients that the body needs but cannot produce on its own.
Key Facts
- 76% of the global population does not meet the recommended intake of omega-3 fatty acids.
- Omega-3s linked to health benefits include eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
- Adults should consume at least 250 mg of EPA and DHA daily; pregnant women need an extra 100–200 mg of DHA.
- Omega-3s support heart health, brain development, and reduce inflammation.
- Common sources of EPA and DHA are oily fish like mackerel, salmon, and sardines.
- Many people find it hard to get enough omega-3s through diet alone due to cost, fish availability, and dietary habits.
- Supplements, including algae-derived omega-3s for vegetarians and vegans, can help meet intake recommendations.
- Omega-3s are associated with a decreased risk of depression and Alzheimer's disease.
