Here’s the original seasoning mix - https://marionkay.com/product/chicken-seasoning-99-x/
So if the first listed ingredient represents the most abundant ingredient...
Also, such a cop out that the FDA has allowed "other natural spices" to be a legit listing. Supposedly to protect corporate secrets blah blah. What if someone is allergic to one of those "natural spices". Either we're for accurate food labeling for the public's safety, or we're not. This in between state highly suggests we're not.
It's seasoning, so it doesn't seem surprising at all that MSG would be pretty high on the list. Do you think that's bad?
Certainly there were restaurants trying to sell you the "5-Hour Energy" equivalent of MSG and some cuisines tend to get closer to doing that naturally. But also you shouldn't directly or indirectly blame the people that make that food for you, just as it is silly to blame all coffee shops for the caffeine headaches and migraines you sometimes get if you don't watch how much coffee you are drinking.
Anyway it doesn't matter.
