Why carbohydrates need for the central nervous system?

Carbohydrates are essential for the central nervous system because they serve as the primary energy source for brain function. The brain relies heavily on glucose, a simple carbohydrate, to fuel its activities, including cognition and neurotransmission. A steady supply of glucose is crucial for maintaining optimal brain performance, as it supports processes such as memory, attention, and overall mental clarity. Without adequate carbohydrates, cognitive function can decline, leading to difficulties in concentration and mental fatigue.
