Of the total amount of glucose energy consumed by the body each day, about 20% is used by the brain and nerve cells.
The brain constitutes about 2% of the total body but it is one of the main consumers of energy derived from glucose.
The energy provided by glucose is used for the proper functioning of the brain. It generates ATP which is an energy source that is responsible for r neuronal and non-neuronal cellular maintenance and generates neurotransmitters.
Thus glucose-derived energy is critical for the health of the brain. Lack of energy can cause several brain diseases.
