Siim Land: 95-Year-Old Scientist: This Nutrient is Critical to Brain Evolution
Peer-Reviewed Research
Key Takeaways
- Prioritize DHA (docosahexaenoic acid) – This omega-3 fatty acid is critical for brain function and evolution, found primarily in marine sources.
- Consume marine-based omega-3s – Land-based foods provide arachidonic acid, but DHA comes exclusively from the marine food web (fish, algae).
- Support brain and eye health – DHA is essential for both brain signaling systems and visual function.
Notable Quotes
“Docosahexaenoic acid was singularly important in the signaling systems, not only of the brain, but also of the eye.”
Bottom Line
Increase intake of marine-sourced DHA (through fatty fish or algae-based supplements) to support optimal brain and eye function.
