Delayed increase of Ca2+ influx elicited by glutamate: role in neuronal death. Just removing gluten, dairy products, additives, and processed foods can make a huge difference to the levels of glutamate and aspartates in the diet. In the case of children with autism, the immune system is overactive and if the child has a diet of excessive glutamates, then an inflammatory condition in the brain called excitotoxicity is triggered.

Many people have a sensitivity to glutamate and a higher percentage are children as they have under-developed myelin sheaths, which is the protective coating around nerves (like insulation on wires) which makes them more prone to the stimulating effects of glutamate. Perturbations in the brain's glutamate-glutamine cycle, such as increased extracellular levels of glutamate, loss of astroglial glutamine synthetase, and changes in glutaminase and glutamate dehydrogenase, are frequently encountered in patients with epilepsy. Grains Grains, such as wheat, barley and oats are highest in glutamate. Eating protein with each meal and not going more than 3-4 hours without eating is important to keep blood sugar level.
