While MSG and Umami may be chemically similar, there is an important distinction that significantly affects the way it reacts in your body.
Umami is distinctly different from sweet, sour, salty, and bitter. It makes the mouth salivate and leaves an aftertaste that many find pleasant but difficult to describe.
Professor Ikeda found that the amino acid glutamate is largely responsible for Umami. Many foods have Umami, especially seaweeds (sea/ocean vegetables); natural glutamate gives food their Umami flavour.
The Problem with MSG
While MSG and umami may be chemically similar, there is an important distinction that significantly affects the way it reacts in your body. Umami flavour, or natural glutamic acid (glutamate), found in natural foods is “bound” to other amino acids or proteins. The glutamic acid that is MSG is not.
MSG is a synthetic reproduction of natural glutamate. As free (unbound) glutamate, it is added to foods to enhance flavour and mimic natural Umami. Like most synthetic isolates, MSG has its fair share of problems. It has been linked to inflammation, type 2 diabetes, and the destruction of liver tissue.
Interestingly, Umami is one of the first flavours that a newborn infant encounters. Research has found that glutamate is the most abundant amino acid in breast milk, making up more than 50% of the amino acids in breast milk. The naturally high concentrations of glutamate (Umami) in breast milk support newborn gut tissue. Glutamate is an energy source for cells that make up the lining of the gut.
In adults, Umami is equally important. Studies show that glutamate drives our digestion, sending signals to the stomach, small intestine, and liver. Besides its role in digestive health, glutamate is also an excitatory brain chemical. It plays an essential role in learning and memory. The body uses glutamate to produce another brain chemical called GABA (gamma-aminobutyric acid), which is a calming and inhibitory brain chemical in the adult brain.
Shortly after his discovery of Umami in 1908, Professor Ikeda patented glutamate salt, or monosodium glutamate (MSG), and it has been produced commercially ever since. Some nutrition “experts” may claim that Umami and MSG are one and the same, but this is far from reality. Part of the problem is that MSG mimics natural glutamate’s ability to initiate certain processes in your body. Glutamate’s role in brain development and brain health points to why MSG (synthetic glutamate salt) has such a bad reputation.
In his book “Excitotoxins: The Taste that Kills”, Dr. Russell Blaylock, a retired board-certified neurosurgeon, explains that MSG overexcites the cells in the body to the point of damage or death. The body’s inability to utilise glutamate properly has been linked to serious disorders and potentially even triggering/worsening learning disabilities, Alzheimer's disease, Parkinson's disease, Lou Gehrig's disease, and more.
