HUMAN NUTRITION

Detailed explanation-1: -The mammalian brain depends upon glucose as its main source of energy, and tight regulation of glucose metabolism is critical for brain physiology.

Detailed explanation-2: -Carbohydrate is an essential nutrient that is an excellent source of energy (measured as calories) for the body and is the preferred fuel for the brain and nervous system. All forms of carbohydrate increase a person’s blood sugar level, depending on the amount of carbohydrate in the food.

Detailed explanation-3: -Glucose is the essential metabolic fuel for the brain. Acute and severe reduction of brain glucose leads quickly to impairment of cognitive and reflex function, autonomic failure, seizures, loss of consciousness, and permanent and irreversible brain damage and, if not rapidly corrected, can be lethal.
