MSG, or Monosodium Glutamate, is found in almost all processed foods today. It’s all over the grocery store in its many forms and in every fast food restaurant (from what I can figure out). A short explanation of it is that it’s a neurotransmitter that stimulates all the systems in your body. Companies put it in food because it excites your senses for something like two hours and is supposed to make you think your food tastes better than it really does.
The makers of MSG say it isn’t bad because it does occur naturally in all foods. Basically, the more flavorful it is, the more glutamate it has in it. In people who are highly allergic to MSG, foods high in glutamate can bother them, but shouldn’t be avoided by most people. Some foods high in glutamate are Parmesan cheese, peas, corn, and tomatoes.
But the naturally-occurring MSG is different than man-made MSG. If you’ve read my blog before, then you know that I am against all man-made ingredients. Our bodies were not made by man so our bodies just have a hard time digesting man-made ingredients.
Why is it bad?… it excites your whole body and can make any sensitivities worse. For example, I am allergic to MSG by itself because of what it’s made from – but if I eat it with something else I am allergic to, it makes it a lot worse because it makes my body get a lot more excited than it would have otherwise.

Some MSG symptoms include:
Now, I think this list is a little overboard – but I believe if you have other health issues and weaknesses in these areas, then MSG will make all these things a lot worse.
What is MSG made of? I can’t even figure that out for sure. That’s because it’s made from a lot of different things. Generally, they take something that is perfectly healthy for you, like corn and extract out the naturally occurring glutamate. Strong acids, alkalies, enzymes, bacteria, and heat are used to hydrolyze animal, vegetable, or milk products. So, manufacturers claim it’s “natural” all the time since it starts from natural sources, but since they change it so much, that’s not natural to me.
If you ask me, our bodies are really only meant to process things in the forms that Heavenly Father put them on the earth. Our bodies aren’t programmed to recognize man-made things and, as a result, we have a lot of symptoms that build up over the years so we don’t even know that it’s the MSG. (see this link)
Here are the names of things to look for on the labels if you want to avoid MSG (basically anything that doesn’t occur in nature should be avoided):

This is a very informative post. I have a sensitivity to MSG and I make sure to ask Asian restaurants if they use it before ordering. I also have severe food allergies that have put me in the hospital ER with anaphylaxis so I carry an epi-pen. It is a frustrating thing; living with allergies and not knowing exactly what you are allergic to until it’s too late. Thank you for posting!
I had no idea that all of these symptoms could be caused by this. I will watch much more carefully now!
My husband actually figured out that is what caused my childhood seizures! Smart man! Actually, you are better off shopping the exterior of the store and making most things from scratch (soups, salad dressings, bbq sauce, etc)
When my oldest son was a toddler, I found out thru trial and error that he had a MSG issue. I noticed when he ate canned pastas he would act out more. Eliminated those from his diet and kept him away from caffeine as well and he returned to a normal better behaved child.
I found out about my sensitivity to MSG after eating at a Chinese restaurant for the first time when I was a teenager. I try to avoid it but it makes it difficult with so many hidden names.
Amazing how many products have MSG! It is a good reason to cook/bake your own food!
Wow that stuff is in a lot more foods than I thought. The hidden name list is very informative I only looked for the obvious MSG before now I’m better armed to avoid a lot more MSG thanks to your post. # thumbs up and thank you.
You’re welcome! It’s crazy how much is hidden in things and the package will sometimes say it doesn’t have MSG but then it will have yeast extract or something. . .
Thank you for the very informative post. The bad feeling from the results of eating foods with MSG is longer lasting for me than the short-term good feeling eating the MSG foods gives me. The hidden names list is very helpful.
There are a lot more symptoms than I originally thought. I will have to pass this info on. Thank you
I wasn’t aware that MSG was in so many products…. I guess I was just thinking mainly things like chinese food, soy sauce, etc, since those are the things you hear about
