Our body needs a constant supply of energy in order to properly function. This energy is usually obtained from glucose.
Glucose is an essential sugar that acts as the main fuel in most of our organs and tissues. It is commonly known as “sugar” and is obtained from food and drink.
In addition, in order to avoid needing to be continually eating; our bodies have a really complex glucose storage-recovery system.
Thanks to this, we are able to store part of the energy obtained by feeding; mostly in the liver, muscles and fat.
By contrast: our body recovers stored glucose when fasting, doing an intensive physical activity, being ill or many other situations that implies a greater energetic waste.
In this way, our blood sugar levels are maintained
consistently within a range of blood glucose that is considered “healthy”.
