Everything You Need to Know About MSG

Have you heard of MSG? If you’re anything like me, you might not even know what it is, even though there are tons of conflicting articles about the actual health safety of consuming foods that contain MSG.

What is MSG?

MSG is short for 'monosodium glutamate,' which is a synthetic form of glutamate, a naturally-occurring amino acid found in certain foods. It was created in the 1900's by Kikunae Ikeda, who was a chemistry professor at the Imperial University of Tokyo. During his early work, Ikeda first discovered that humans could experience a fifth taste called 'umami' (derived from the Japanese word umai, which means 'delicious') when trying to replicate the distinct savory taste of his wife’s kelp broth.

He successfully isolated glutamate as the molecule responsible for umami and then continued to create a more shelf-stable form of glutamate, called monosodium glutamate, to be sold in supermarkets. MSG is commonly used today as a food additive in most processed foods, such as French fries, chips, bottled salad dressing, as well as your standard Chinese takeout.

Why is it Added to Foods?

Is it Safe to Consume MSG?

But, anecdotally speaking, some people have experienced adverse effects from consuming MSG-added foods (notably Chinese food) like headaches, flushing, sweating, nausea, and chest pain. Funnily enough, some medical experts have termed these symptom clusters 'Chinese restaurant syndrome.' Regardless, there’s inconsistent evidence demonstrating that MSG is actually unhealthy, but of course, it’s safest to consume everything, including MSG, in moderation.

How Will I Know if There’s MSG in my Food?

The best advice is to read the food label if there’s one available. Just be mindful that you might not always specifically find 'MSG' on the label since the FDA doesn’t require food companies to list MSG. Instead, you might see other names for MSG, such as hydrolyzed protein, autolyzed yeast, glutamic acid, or yeast extract. If you’re eating out, don’t be afraid to ask your waiter or chef if the restaurant uses MSG in its cooking. Otherwise, keep an eye out for foods that commonly have MSG added, especially Chinese takeout.

Are There Any Alternatives to MSG?

Some examples are seaweed, soy sauce, miso, tomatoes, aged cheese, mushrooms, Worcestershire sauce, and fish sauce. If you’re interested, you can find a more extensive list of umami-rich foods here.

Hopefully, this article provided you with everything you needed to know about MSG. I think the most important takeaway is that while there’s still conflicting evidence about whether MSG consumption is necessarily unsafe or unhealthy, it’s always best to consume MSG (and any other food or food additive) in moderation.
