Researchers from the US have found evidence that suggests eating cinnamon might have a positive impact on your ability to learn.
The research has only been conducted in mice for now, but, if confirmed, the findings might offer a simple, at-home way to help those who struggle to learn new tasks, as well as allowing researchers to better understand the underlying mechanisms in the brain that control learning.
“Understanding brain mechanisms that lead to poor learning is important to developing effective strategies to improve memory and learning ability,” said lead researcher Kalipada Pahan from Rush University Medical Centre in Chicago.
To fully understand the new study, you first need to understand what controls learning. While the reason some people learn more easily than others is still largely a mystery, researchers have shown that the ability to learn lies within the hippocampus – a part of the brain that organises, generates, and stores memories.
Researchers also know that poor learners have less CREB – a protein that is vitally important to make memories – and more GABRA5, a protein that generates ‘tonic inhibitory conductance’, meaning it basically slows the brain down.
For the new study, the Rush University team fed ground cinnamon to mice because – when metabolised – it turns into sodium benzoate, a common drug that the team says is used to treat brain damage. Their hypothesis was that, as this substance enters the brain, it might increase CREB and decrease GABRA5 production, leading to better memory, brain plasticity, and, therefore, an increased ability to learn.
To test this, the team differentiated which mice were naturally good and bad learners by training them to find a single hole in a maze. Then, they analysed how much better the ‘bad learners’ became after injecting them with dissolved, ground cinammon (the team doesn’t specifically state how much).
In the end, they found that the bad learners became better after eating the delicious spice while the good learners pretty much stayed the same, suggesting that cinnamon might be a good, cheap way to aid those who struggle with learning – but not beneficial to those who are already good at it.
Until tomorrow: We are at our very best, and we are happiest, when we are fully engaged in work we enjoy on the journey toward the goal we’ve established for ourselves. It gives meaning to our time off and comfort to our sleep.
