Alzheimer’s triggered by MSG? Author and MSG-survivor Adrienne Samuels, Ph.D. traces the link

Is there a connection between MSG and Alzheimer’s? Author and MSG survivor Adrienne Samuels, Ph.D. traces the link in the study “Dose dependent toxicity of glutamic acid: A review.”

While a little bit of MSG may not obviously hurt you, remember, you can’t see the brain damage caused by eating MSG or the 40+ other food ingredients that contain MSG’s brain-damaging manufactured free glutamic acid (MfG). You won’t read about this in the New York Times or hear it from the FDA because the glutamate industry wouldn’t allow that, but you can read the open access study published online by the International Journal of Food Properties . (Clicking on the green PDF button at the journal page will make it easier to read.) And if the glutamate industry manages to have it taken down, we’ll put it back up.

It’s a simple story. L-glutamate in food, which is essential to normal body function and is the major neurotransmitter in humans, becomes excitotoxic – brain damaging — when present outside of whole protein, in excess of what a healthy human can accommodate. Put another way, if a protein is broken into individual amino acids before it is ingested, those free amino acids take on a toxic potential that they wouldn’t have if consumed in unprocessed, unadulterated protein.

As far as the excess of these free amino acids goes, there is quite enough MfG readily available in processed and ultra-processed foods, snacks and drinks to prove excitotoxic.

The fact of MSG-induced toxicity has been revisited in “Dose dependent toxicity of glutamic acid: A review.” This study also confirms the fact that excitotoxins such as MSG ingested by a mother will pass to the fetus across the placenta and be passed to the newborn through mothers’ milk.

The take-away is that food additives containing MfG, such as MSG, on one hand clearly cause human brain damage, and on the other may very well contribute to the myriad of abnormalities now recognized as being associated with glutamate, including: Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, stroke, ALS, autism, schizophrenia, depression, obsessive-compulsive disorder (OCD), epilepsy, ischemic stroke, seizures, Huntington’s disease, addiction, attention-deficit/hyperactivity disorder (ADHD), frontotemporal dementia, headaches, asthma, diabetes, muscle pain, atrial fibrillation, ischemia, trauma and autism.

MSG does more than cause migraine headache and Chinese Restaurant Syndrome. MSG destroys brain cells.

  1. So I have a question. Yellow prussiate of soda, found in many varieties of salt, produces exactly the same reaction in my husband and two sons as MfG (irregular heartbeat in two of them, seizures in the third). Is there anyone who can explain this? And is there a way to determine if the salt on the ingredients label also contains Yellow prussiate of soda?

    1. Table salt usually contains flowing agents which contain manufactured free glutamate (MfG). RealSalt is a product that claims to contain rock salt, only. You can reach then at 800-367-7258.

      The only way to determine if a particular salt product contains yellow prussiate of soda is to ask its manufacturer. But realize that there might be other additives besides yellow prussiate of soda that contain MfG. Your time might be better spent making sure that the rock salt or mineral salt that you choose is free of MfG.

      Hope this answers your question.
