Aspartate can enter the same receptor site (parking space) as glutamate to affect the neurones and create excess firing of the nervous system and result in damage to the neurones. Hynd MR, Scott HL, Dodd PR. Dr. This diet is high in fats and low in carbohydrates and forces the brain to use fat-derived ketone bodies instead of glucose as the major energy source. 5) Tree nuts (e.g. 2.

However, glutamate uptake by the brain across the Blood Brain Barrier is very low. Glutamine in food is usually drip fed to the body, and through a series of biochemical processes, converted to glutamate daily as needed for repair and regeneration, and to serve the nervous system so that it can function properly. Neurochem Int. Excessive glutamate found in the brain convert to GABA automatically through an enzyme called Glutamic Acid Decarboxylase (GAD). They are caused by abnormally excited electrical signals in the brain.
