Excitotoxicity

This is a great talk about your brain, https://www.youtube.com/watch?v=tTSvlGniHok

This is a great summary of this information.

This 2004 article has advice on defending against excitotoxins, although I seriously question the amino acid suggestion.

At the same time, excitotoxins need to be removed from the diet. When the brain is injured it is 100 times more sensitive to excitotoxins, so it is especially important to remove excitotoxins.  Foods with excitotoxins include:

• Glutamic Acid
• MSG
• Anything glutmate (Monopotassium glutamate, magnesium diglutamate, etc)
• Hydrolyzed anything, (Hydrolyzed vegetable protein, hydrolyzed soy protein, etc)
• Vegetable protein
• Textured protein
• Plant protein
• Autolyzed anything (Autolyzed plant protein, autolyzed yeast extract, etc)
• Yeast extract
• Malt extract
• Soy Sauce Extract
• Yeast nutrient
• Caseinate
• Carrageenan
• Aspartame
• Sodium Cyclamate
• Nutrasweet
• Broth
• Stock

Exceptionally high excitotoxin foods are:

• gravies, salad dressings (especially diet)
• soups (Campbell's is the worst)
• diet foods and drinks
• liquid amino acid preparations
