Indeed. It turns out that “MSG headaches” are just high sodium level headaches, either through dehydration, unbalanced electrolytes, elevated blood pressure or whatever else higher than normal sodium levels cause headaches. The same headache could be caused by salt. MSG actually makes recipes require less of other flavor ingredients, including salt. It’s also often found in dishes that still contain relatively massive amounts of salt.

So a little MSG to get your taste buds extra sensitive to other flavors is a net good. Just don’t eat too much sodium altogether, balance your electrolytes, and stay hydrated.

There's not "nothing" wrong with MSG. But msg is fine in moderation, just like salt, fat and sugar are all fine in moderation too

Crazy how most of the negative hype around that, total nonsense people have believed for decades now, started from some doctor making a joke paper in the New England Journal of Medicine because one of his other doctor friends was saying that orthopaedic surgeons were too stupid to get something published in there and bet like 10$ that to my recollection didn't even get paid (although this says 2024 I swear I remember reading about this 5-10 years ago):

But the story doesn’t end there. In 2024, a major twist emerged when a retired orthopedic surgeon and Colgate University trustee named Dr. Howard Steel contacted Colgate University professor Jennifer LeMesurier to make a shocking claim: He was the author of the letter. Goaded by a friend who had bet him $10 that he wasn’t smart enough to have an article published in The New England Journal of Medicine, Dr. Steel said he had invented the sensationalistic “strange syndrome” and the persona of Dr. Robert Ho Man Kwok to win the wager, LeMesurier recounted in a 2025 episode of This American Life.

But they were involved in price fixing lysine. And that was wrong.

The argument for MSG is that it's "naturally occurring in food anyway" and that it is a substitute for worse things - which sounds like the same argument for aspartame.

The bottom line is you don't know for sure and it's developed under commercial incentives.

It's probably ok carries just as much weight as you probably don't need it.
