Is MSG keto friendly? MSG does get a lot of bad press, most of which has been debunked in recent years. You will be pleased to know that MSG can be eaten on a keto diet without it kicking your out of ketosis. Read on to find out more about MSG and how you can incorporate it into a keto diet.

What Is MSG?

Monosodium glutamate, or MSG, was first created in a Tokyo laboratory in 1908, eventually making its way into Western cooking by the 1920s.

MSG is essentially a salt, produced by combining the mineral sodium with glutamate, an amino acid.

It is used as a flavor enhancer in savory foods to provide an umami, or meaty, taste and was first popularized in Chinese cooking.

What Is The Nutritional Value Of MSG?

MSG is a wasteland when it comes to any kind of nutritional value. Typical servings weigh just 1g and contain 0 calories, fats, carbs, and protein. The only nutrient of note is 125mg of sodium.

Carbs in MSG: MSG has zero carbs, meaning it will not spike your blood sugar levels

How Many Net Carbs Are There In MSG?

As MSG doesn’t contain any cabs, its net carbs are also 0.

So, is MSG ok for a keto diet?

Is MSG Keto Friendly?

By definition, yes- MSG is keto friendly, it has zero net carbs, so is not going to break your macros and kick you out of ketosis.

It can be a great way to add flavor to food that is missing certain nutrients, like carbs, while keeping the actual nutritional impact very low.

However, MSG is often avoided by people on a keto diet as it is essentially a chemical, or more specifically- a food additive.

Why Is MSG Controversial?

Chemically, MSG is degraded into sodium and glutamate during digestion, neither of which are damaging to health.

Sodium is an essential mineral, with the FDA recommending an upper limit of 2,300mg per day.

Glutamate is an amino acid obtained through food. It is one of the most abundant amino acids in the body and is also used as a major neurotransmitter throughout the nervous system.

Concerns around MSG as a food additive began in the 60s with a study that identified “Chinese restaurant syndrome” [1].

Although the findings of this research have largely been debunked, fears still surrounded the widespread use of MSG.

Some early studies found that it caused brain damage in rats, but closer inspection reveals that these findings were only possible when administering astronomically large doses of MSG, which you simply wouldn’t find in food.

More recent research into humans hasn’t found any association between normal levels of MSG and symptoms including headaches, weight changes, allergies, or hypothalamic disruption.

Is MSG safe? There is no science to suggest that MSG is not safe for human consumption.

If anything- the most justifiable reason for avoiding MSG is that it is a food additive, so can’t be factored into a clean-eating diet.

What Are The Health Benefits Of MSG?

Unsurprisingly there aren’t really any health benefits to MSG as its only use is to improve the flavor of food.

Some people may choose to limit additives in their food, but ultimately MSG is ok for a keto diet.
