Hence, the epilepsy community would benefit from a dietary option that could reduce/eliminate the drawbacks and side effects of current therapeutic diets, while optimizing micronutrient and antioxidant intake. Glutamates role in the body is to stimulate our brain cells to deliver messages throughout the body and is particularly important for memory, learning, and general growth and development of the brain, especially for children. If you have leaky gut syndrome, aka intestinal permeability, from bacterial overgrowth or food intolerances etc, the inflammation in the gut can also make the blood brain barrier leaky or more permeable to let substances in that should not get in. Because microglia cells are immune cells, they have the mechanism to become inflamed and trigger excitotoxcity at the same time they are acting as an immune cell; this condition is called immunoexcitoxicity. 2014;34(5):876882. Changes in human brain glutamate concentration during hypoglycemia: insights into cerebral adaptations in hypoglycemia-associated autonomic failure in type 1 diabetes.

However, it can also be in an unbound or free form, where it is no longer bound to an amino acid, so it is then digested and absorbed faster by the body, creating a spike of glutamate in the blood which can create damage to our nervous system and beyond. If the brain is damaged or exposed to toxins, these activated microglia cells can become destructive to the brains cells and connections. Database: Standard Release (Common) View. Rowley, N.M., et al. Acta Paediatr. 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. Just removing gluten, dairy products, additives, and processed foods can make a huge difference to the levels of glutamate and aspartates in the diet. Carefully note any patterns of symptoms that emerge. Tree nuts such as pecans and macadamias are the lowest. The lungs, the ovaries, all the reproductive systems and sperm itself, adrenal glands, bones and even calcification are all controlled by glutamate receptors.

Enhanced susceptibility to stress and seizures in GAD65 deficient mice. Serotonin is the neurotransmitter that regulates: Glutamate makes the interaction of all these neurotransmitters in the brain function so we can: Glutamate receptors also have a major role in not only long- and short-term memory but also the development of memories from experience. Quite a few alternative treatment options are available, and these include herbal supplements, biofeedback, acupuncture, yoga, and breathing exercises.
