A recent study suggests that the trace element copper is vital for brain health, with optimal intake potentially improving memory and offering protection against dementia in older adults. The research indicates that both a deficiency and an excess of copper can lead to neurological problems.
Key Research Findings
A study published in “Scientific Reports” analyzed data from 2,420 older Americans and found a significant link between copper consumption and cognitive ability. Key findings include:
- Improved Cognition: Individuals over 60 who consumed more copper (above 1.2-1.6 mg/day) demonstrated better results in memory and attention tests.
- Optimal Range: The cognitive benefits appeared to plateau after an intake of 1.6 mg per day, with no further improvements observed at very high levels.
- Post-Stroke Benefits: The positive effects were most pronounced in individuals who had previously suffered a stroke, linking higher copper intake to significantly better overall cognitive functioning.
Conclusion and Dietary Recommendations
Copper is an essential microelement for the nervous system, supporting neurotransmitter synthesis, protecting nerve cells from damage, and aiding in the formation of the myelin sheath. While the study shows a promising correlation, researchers note that further investigation is needed to establish a direct causal link. To ensure adequate copper levels, the article recommends a diet rich in foods like liver, whole grains, seafood, nuts, mushrooms, dark chocolate, and certain fruits and vegetables like avocados and tomatoes.
Mentoring question
After learning about the potential cognitive benefits of copper, how might you assess your own diet to ensure you are getting an adequate amount from natural food sources?
