This study looked at more than half a million blood samples from people around the world to measure levels of omega-3 and omega-6 fatty acids. Numerous studies have shown these fats are important for health, and that the balance between them can affect the risk of long-term diseases.
The researchers found that many populations worldwide have low levels of omega-3s and an unhealthy balance between omega-6 and omega-3. This pattern was consistent across different regions and groups, confirming earlier findings.
The study also showed that a simple finger-prick blood test can provide an accurate and affordable way to check fatty acid levels on a large scale. The researchers say their results demonstrate the usefulness of fingertip testing as a practical and cost-effective approach to help promote overall health and well-being.
