Increase glutathione - reduce glutamate levels
--------------------------------------------------------------------------------
One of the best ways to counter Glutamate excitotoxicity and resulting neuron deaths is to increase glutathione levels.
Unfortunately, glutathione supplements taken orally are very poorly absorbed and have not raised glutathione levels in the blood. So save your money.
The glutathione precursor, N-acetyl-cystine(commonly just called NAC) provides sufficient sulphur containing amino acid (a duo or dimer of cysteine) to boost glutathione levels.
NAC is readily absorbed and boosts glutathione levels quite well.
Glutathione contains the following 3 amino acids linked together: Glutamate—cysteine--glycine.
There are some foods that that boost glutathione levels. I do not know all of them but a few are Asparagus, avocados, and walnuts which are known to be a rich sources of glutathione.

Also broccoli, brussels sprouts, cabbage and cauliflower all contain cyanohydroxybutene which increases glutathione levels.
Avocados, peaches, bueberries and watermelon are also reported to raise glutathione levels.
Several spices including cinnamon, cardamom and curcumin found in turmeric raise glutathione levels.
Alpha Lipoic Acid (ALA) promotes the synthesis of glutathione in the body. Food sources of ALA include spinach, broccoli, tomatoes, peas, Brussels sprouts, and rice bran. Real Hellman’s Mayonnaise also provides 660 mg of ALA per 1 tablespoon.
