Profe Claudio Nieto: Sugar and the Brain

Profe Claudio Nieto talks to you about sugar and the brain.

The brain is mainly fueled by glucose.

Fat also plays an important role in the brain, but sugar also has a significant function.

In the complex web of knowledge about human physiology, there’s a detail that has puzzled many: if the brain is primarily fueled by glucose, why is it predominantly composed of fat?

This seemingly contradictory enigma is one of the starting points to delve into the fascinating world of neuroscience and nutrition.

Throughout our academic journeys, we’ve been repeatedly told that the brain requires glucose to function properly.

We’ve even been advised to start the day with a dose of sugar to boost our brain energy. Who hasn’t succumbed to the temptation of sweetening their morning coffee with a couple of spoonfuls of sugar?

It seemed like a simple equation: brain needs glucose, sugar provides glucose. However, when we delve into the study of brain physiology, we discover a much more complex and fascinating reality.

The brain, that organ that defines us as human beings, is mostly composed of fat. Yes, you read that right! Close to three-quarters of its composition is fat in nature.

Even once water is removed, the brain is constituted of 90 to 95% fat!

This leads us to ask: what then is the role of fat in brain function?

The answer lies in the importance of essential fatty acids, fundamental components of cell membranes and myelin sheaths, essential for efficient transmission of nerve impulses and cognitive health.

During our physiology studies, we’ve marveled at the complexity of synapses, those connections between neurons that allow cerebral communication.

And surprisingly, we’ve discovered that cerebral fluidity and cognitive processes like memory, concentration, and attention are intrinsically linked to the presence and quality of essential fats in our brain.

So, where does sugar fit into this puzzle?

Apparently, their roles in cerebral metabolism are more subtle than we initially assumed.

This enigma invites us to delve even further into the complex interplay between nutrition and brain function.

In upcoming installments, we’ll delve deeper into this fascinating topic, unraveling the mysteries of diet and its impact on our brain health.
