It excites more than just your sense of taste.
It is common to hear the acronym 'MSG' misused.
Often the term is used in reference to any glutamate found in a food or drink, but that is inaccurate.
Specifically, MSG is monosodium glutamate.
The lone sodium molecule easily breaks away from the glutamate protein molecule after ingestion.
This makes MSG a potent excitotoxin.
There are many other sources of glutamate.
For example, gelatin is produced by hydrolysis.
This creates a product with 10% glutamic acid.
Following is a multipart video series about MSG featuring Dr. Russell Blaylock.
Near the end of Part 1, and again in Part 2, the news team mistakenly labels aspartame as a form of MSG.
As indicated above, errors like this are common.
Aspartame is excitotoxic but it's a completely different substance.
Here is a list of excitotoxins used in foods and drinks.

In Part 4 the news team suggests buying milk that is pasteurized but not homogenized.
Instead, consider investigating whether milk is appropriate for consumption — the majority of people are intolerant and don't know it.
If milk is tolerated, consider finding a source for raw dairy products.
Organic Pastures is an example in California.
