Excitotoxins are chemicals substances that overstimulate certain type of cells in the brain, all those of the nervous system and many other organs. In high and excessive amounts these cells become damaged and may die.
Dr. Bob here, and in this post I’d like to share with you some things you may be currently consuming (excitotoxins) which may be severely damaging your health!
The underlying mechanism of excitotoxins has been attributed to the following diseases: Alzheimer’s, Parkinson’s, multiple sclerosis, strokes, autism, Huntington’s disease.
Excitotoxins have also been found to be associated with the following diseases: migraines, diabetes, atherosclerosis, sudden death from heart disease, eye diseases, digestive disorders, autoimmune diseases, growth of tumors, spread of cancer and obesity.
The Most Common Excitotoxin is Glutamate and where it’s commonly found.
Glutamate is the main component of Monosodium glutamate (MSG)
As a rule, the more a food is processed the more likely it is to contain MSG. Foods that commonly use MSG include potato chips, flavored crackers, canned soups, dry soup mixes, canned meats, diet foods, soy sauces, salad dressings, cured meats and poultry injected with broth. But reading the labels won’t always help you.
When a food product is 99 percent pure MSG it is called “monosodium glutamate” by the FDA and must be labeled as such. However, when a food product contains less than 99 percent MSG, the FDA doesn’t require that the MSG be identified so it often appears on labels in various disguised forms, such as “hydrolyzed vegetable protein,” “spices” and “natural flavoring.”
Here’s a quick list of potentially suspect ingredients to watch for:
Ingredients that may contain 30 to 60 percent MSG:
hydrolyzed vegetable protein
hydrolyzed protein
hydrolyzed plant protein
plant protein extract
sodium caseinate
calcium caseinate
yeast extract
textured protein
autolyzed yeast
hydrolyzed oat flour
Ingredients that may contain 12 to 40 percent MSG:
malt extract
malt flavoring
bouillon
broth
stock
natural flavoring
natural beef or chicken flavoring
seasoning
spices
Ingredients that may contain some MSG:
carrageenan
enzymes
soy protein concentrate
soy protein isolate
whey protein concentrate
some soymilk
Although I have presented the downside of excessive glutamate it is important for me to let you know that glutamate does have positive health benefits.
These would include the following benefits:
- Acting as an important neurotransmitter in the brain — it has excitatory effects, meaning it makes neurons more likely to fire
- Serving as a precursor for the neurotransmitter GABA (gamma-aminobutyric acid), which is the main inhibitory neurotransmitter in the central nervous system
- Supporting growth and development of the brain
- Helping cells survive and differentiate and supporting formation and elimination of nerve contacts (synapses)
- Supporting cognitive functions, including learning and memory.
- Stimulating gut movement by increasing gut serotonin levels
- Producing the antioxidant glutathione
- Regulating inflammatory processes
So, what is one to do when it comes to this special and sometimes detrimental neurotransmitter?
One answer is to get tested if you suspect glutamate toxicity. If your glutamate levels are high, then you have an objective marker to carefully monitor as you taper and avoid foods high in glutamate.
If you don’t want to invest in testing the next best step is to avoid foods in glutamate and see if you see an improvement in your symptoms and/or see a doctor that can create for you a specific protocol aimed at detoxifying you of this culprit.
Natural plant products and extracts that reduce glutamate and immunoexcitotoxicity
Curcumin, quercetin, green tea catechins, balcalein, and luteolin have been extensively studied to dampen the detrimental impact of excessive glutamate.
If you suspect that your health issues are associated with glutamate toxicity, I encourage you to contact our office or, talk with your functional medicine healthcare provider. They can best advise you on the steps to take to improve your health.
Here’s to “the best performance of your life!”
God bless,
Dr Bob
