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. Once there is brain inflammation, special immune cells called microglia cells, which are normally in a semi-resting state, now become very active trying to reduce glutamate levels in the brain by making sure they are not too high.

Many people with epilepsy turn to alternative treatment options either alone or in combination with conventional medication. However, the brain has a more difficult time keeping low levels of glutamate outside of the cells when the following are present: Research shows that the development of glutamate-induced brain-cell death depends strongly on calcium channels in the brain. We dont have to look to far to see children eating foods such as processed meats like devon or similar, or foods with MSG (2-minute noodles for example) plus a no added sugar drink that contains aspartate (diet cola/soda) and as a result have hyperactivity, attention deficit or behavioural issues.

Youre stimulating all of the glutamate receptors. Once the villi are damaged, they can no longer absorb minerals and vitamins, fats and amino acids, nor can they protect the brain from the thousands of toxins in our world today. They are caused by abnormally excited electrical signals in the brain. Adverse effects include constipation, low blood sugar, and gastrointestinal reflux. One of the reasons that we see the above lists of symptoms occurring is when people (especially children with underdeveloped nervous systems) eat foods and additives that contain the nervous system stimulants glutamate and aspartate, another neuro-stimulant.

Foods and Substances to avoid on a Low Glutamate Diet. Keeping a balance between the two is very important otherwise an excess of glutamate over time can cause neurological damage and inflammation to the nerves, which can also lead to neurodegenerative conditions such as: The body normally keeps all the neurotransmitters balanced in the brain, but for some this doesnt always happen.
