The human brain needs magnesium and zinc in order to function. It is thought that primitive hunter gatherers must have found seaweed in order to get these nutrients. Seaweed probably played a role in the human’s ability to clearly form thoughts. For coastal hunter gatherers, seaweed provided an inter tidal calorie source. The earliest humans probably did not understand the seasonality of the shellfish in various coastal regions. The seaweed on the other hand could be gathered by women and children.
- It is noted that nutrients have played an essential role in human evolution and one of them is the role of zinc and magnesium in modern brain functioning.
- Nutrient-dense seaweed which were a source of food for the hunter gatherer influenced them a lot as well as the micro-algae that coastal dwellers depended on.
- Human brains have changed and due to the fact that they have been influenced by chance or by accident on the elements that improve cognitive function.
“Nutrient-dense seaweeds could have changed the entire thinking process of coastal cultures, broadening their perspective, enlightening their visionary traits, and stimulating interpersonal communication.”
