Have a question or a request? We love to hear from you!

In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

So, no question/request too big or small 😎

❝Hello, I love your newsletter 🙂 Can I have a question? While browsing through your recepies, I realised many contained MSG. As someone based in Europe, I am not used to using MSG while cooking (of course I know that processed food bought in supermarket containes MSG). There is a stigma, that MSG is not particulary healthy, but rather it should be really bad and cause negative effects like headaches. Is this true? Also, can you get addicted to MSG, just like you get addicted to sugar? Thank you :)❞

Thank you for the kind words, and the interesting questions!

Short answer: no and no 🙂

Longer answer: most of the negative reputation about MSG comes from a single piece of satire written in the US in the 1960s, which the popular press then misrepresented as a genuine concern, and the public then ran with, mostly due to racism/xenophobia/sinophobia specifically, given the US’s historically not fabulous relations with China, and the moniker of “Chinese restaurant syndrome”, notwithstanding that MSG was first isolated in Japan, not China, more than 100 years ago.

The silver lining that comes out of this is that because of the above, MSG has been one of the most-studied food additives in recent decades, with many teams of scientists in many countries trying to determine its risks and not finding any (except insofar as anything in extreme quantities can kill you, including water or oxygen).

You can read more about this and other* myths about MSG, here:

Monosodium Glutamate: Sinless Flavor-Enhancer Or Terrible Health Risk?

*such as pertaining to gluten sensitivity, which in reality MSG has no bearing on whatsoever as it does not contain gluten and is not even made of the same basic stuff; gluten being a protein made of (amongst other things) the amino acid glutamine, not a glutamate salt. Glutamate is as closely related to gluten as cyanocobalamin (vitamin B12) is to cyanide (the famous poison).

PS: if you didn’t click the above link to read that article, then 1) we really do recommend it 2) we did some LD50 calculations there and looked at available research, and found that for someone of this writer’s (very medium) size, eating 1kg of MSG at once is sufficient to cause toxicity, and injecting >250g of MSG may cause heart problems. So we don’t recommend doing that.

However, ½ tsp in a recipe that gives multiple portions is not going to get you anywhere close to the danger zone, unless you consume that entire meal by yourself hundreds of times per day. And if you do, the MSG is probably the least of your concerns.

(2 tsp of cassia cinnamon, however, is enough to cause coumarin toxicity; for this reason we recommend Ceylon (or “True” or “Sweet”) cinnamon in our recipes, as it has almost undetectable levels of coumarin)

With regard to your interesting question about addiction, first of all let’s speak briefly about sugar addiction:

Sugar addiction is, by broad scientific consensus, agreed-upon as an extant thing that does exist, and contemporary research is more looking into the “hows” and “whys” and “whats” rather than the “whether”. It is a somewhat complicated topic, because it’s halfway between what science would usually consider a chemical addiction, and what science would usually consider a behavioral addiction:

The Not-So-Sweet Science Of Sugar Addiction

The reasonable prevailing hypothesis, therefore, is that sugar simply has two moderate mechanisms of addiction, rather than one strong one.

The biochemical side of sugar addiction comes from the body’s metabolism of sugar, so this cannot be a thing for MSG, because there is nothing to metabolize in the same sense of the word (MSG being an inorganic compound with zero calories).

People can crave salt, especially when deficient in it, and MSG does contain sodium (it’s what the “S” stands for), but it contains a little under ⅓ of the sodium that table salt does (sodium chloride in whatever form, be it sea salt, rock salt, or such):

MSG vs. Salt: Sodium Comparison ← we do molecular calculations here!

Sea Salt vs MSG – Which is Healthier? ← this one for a head-to-head

However, even craving salt does not constitute an addiction; nobody is shamefully hiding their rock salt crystals under their bed and getting a fix when they feel low, and nor does withdrawal cause adverse side effects, except insofar as (once again) a person deficient in salt will crave salt.

Finally, the only other way we know of that one might wonder if MSG could be addictive, is about glutamate and glutamate receptors. The glutamate in MSG is the same glutamate (down to the atoms) as the glutamate formed if one consumes tomatoes in the presence of salt, and triggers the same glutamate receptors in the same way. We have the same number of receptors either way, and uptake is exactly the same (because again, it’s exactly the same chemical) so there is a maximum to how strong this effect can be, and that maximum is the same whatever the source of the glutamate was.

In this respect, if MSG is addictive, then so is a tomato salad with a pinch of salt: it’s not—it’s just tasty.

We haven’t cited papers in today’s article, but it’s just because we cited them already in the articles we linked, and so we avoided doubling up. Most of them are in that first link we gave 🙂

One final note

Technically anyone can develop a sensitivity to anything, so in theory someone could develop a sensitivity to MSG, just like they could for any other ingredient. Our usual legal/medical disclaimer applies.

However, it’s certainly not a common trigger, putting it well below common allergens like nuts (or less common allergens like, say, bananas), not even in the same league as common intolerances such as gluten, and less worthy of health risk warnings than, say, spinach (high in oxalates; fine for most people but best avoided if you have kidney problems).

The reason we use it in the recipes we use it in, is simply because it’s a lower-sodium alternative to salt, and while it contains a (very) tiny bit less sodium than low-sodium salt (which itself has about ⅓ the sodium of regular salt), it has more of a flavor-enhancing effect, such that one can use half as much, for a more than sixfold total sodium reduction. Which for most of us in the industrialized world, is beneficial.
