The brain’s only food is glucose, which is carried to the brain in the blood. Only when there is enough blood flow to bring plentiful supplies of glucose to the brain can neurons and glial cells carry out their functions and ensure full consciousness. (Pert, Candace, PhD. Molecules of Emotion. NY: Scribner, 1997, p 289)

The brain consumes the equivalent of a quarter pound of glucose every day, more than any other body organ except for muscles during heavy exercise. The bulk of the energy is used to make neurotransmitters. (Treadwell, Benjamin V., PhD. The Brain: Can We Tweak it? CA:Juvenon Health Journal, Vol 4, No. 4, April 2005, p 12)

The mind is powered by the brain and more than the muscles or any other organ, the brain demands glucose in a steady second-to- second flow. Low blood sugar can cause mental problems (e.g., fatigue, nervousness, anxiety, irritability, depression, forgetfulness, confusion, indecisiveness, poor concentration, nightmares, and suicidal tendency.) (Padus, Emrika, et al. The Complete Guide to Your Emotions & Your Health: New Dimensions. PA: Rodale Press, 1986, pp 20-22)

Carbohydrate (glucose source) is the only source of fuel that the brain can use (it cannot burn fat). It is a most energy-demanding organ, responsible for over half our obligatory energy requirements. Glucose levels decline more during a period of intense cognitive processing… Improved mental ability following a carbohydrate meal has been demonstrated in all types of people (See also Glycemic Index).
