Is it True, that Intelligent people have more zinc and copper in their hair?

The Relationship Between Intelligence and Zinc/Copper Levels in Hair

Intelligence is a complex trait influenced by various factors, including genetics, environment, and brain function. While the idea that intelligent people have higher levels of zinc and copper in their hair has circulated, let’s explore the scientific basis behind this claim.

1. Brain Connectivity and Intelligence:

• Researchers from Goethe University Frankfurt in Germany have investigated brain connectivity patterns in intelligent individuals.

• High IQ is associated with increased activation in the frontal and parietal brain regions1.

• Smarter people exhibit stronger connections between certain brain areas, while interactions are dampened in other regions1.

• These distinct connectivity patterns may help intelligent individuals differentiate between relevant and irrelevant information, enhancing cognitive abilities.

1. Zinc and Copper in Hair:

• Some studies suggest that people with high intelligence retain more zinc and copper in their hair.

• Zinc and copper compete for the same chemical receptors in the body and brain as lead. Lead exposure negatively affects intelligence.

• It’s possible that individuals exposed to more lead absorb less zinc and copper, impacting their cognitive function2.

1. The Right/Left Brain Connection:

• Dr. Paul Eck observed a correlation between zinc, copper, and brain function.

• Copper is associated with creativity and the right brain, while zinc is linked to the left brain.

• Proper balance between these elements is crucial for optimal brain function3.

In summary, while the relationship between intelligence and zinc/copper levels in hair isn’t fully understood, there are intriguing connections. However, it’s essential to approach this topic with scientific curiosity and recognize that intelligence is multifaceted, influenced by various factors beyond trace minerals in hair. 🧠🔬
