What essential brain component, crucial for neurodevelopment in children, is strongly associated with increased gray matter in adults from sardine consumption?

DHA and EPA (Omega-3s)

The impact of sardines extends actively into supporting the nervous system and cognitive function, primarily due to the high content of omega-3 fatty acids, specifically DHA and EPA. These fats are fundamental building blocks for the brain. In pediatric populations, they are recognized as essential for healthy neurodevelopment from an early age. In adults, consistent intake of these fatty acids is linked to measurable improvements in cognitive performance and is specifically associated with an increase in the brain's gray matter volume. Relying on whole food sources like sardines ensures the delivery of these fats alongside other synergistic compounds often absent in supplemental forms.
