Discover the natural sources of MSG in your everyday diet

If you’re short on time, here’s a quick answer to your question: MSG is naturally present in certain foods.

In this article, we will explore the various foods that naturally contain MSG and how it affects our health.

What is MSG?

MSG, or monosodium glutamate, is a flavor enhancer commonly used in various cuisines around the world. It is derived from glutamic acid, an amino acid found naturally in many foods. Glutamic acid is an important component of protein, and it contributes to the savory taste known as umami.

The definition and origin of MSG

MSG was first discovered by a Japanese scientist named Kikunae Ikeda in 1908. He isolated glutamic acid from seaweed and found that it had a unique taste that was different from sweet, sour, salty, or bitter. Ikeda named this taste umami, which is now recognized as the fifth basic taste.

MSG is created through a process of fermentation, where glutamic acid is combined with sodium to form monosodium glutamate. This flavor enhancer has since become widely used in the food industry to enhance the taste of various dishes.

The controversy surrounding MSG

Over the years, MSG has been the subject of controversy and concerns regarding its potential side effects. Some individuals claim to experience symptoms such as headaches, flushing, and sweating after consuming foods containing MSG, a condition known as “Chinese Restaurant Syndrome.”

However, scientific studies have not been able to consistently replicate these symptoms in controlled settings. The U.S. Food and Drug Administration (FDA) recognizes MSG as safe for consumption, and it has been classified as a generally recognized as safe (GRAS) ingredient.

It is important to note that some individuals may be sensitive to MSG, and they may experience adverse reactions. If you suspect that you are sensitive to MSG, it is best to consult with a healthcare professional.

Foods High in Naturally Occurring MSG

Monosodium glutamate (MSG) is a flavor enhancer commonly found in processed foods. However, MSG also occurs naturally in some foods. While the debate about the potential health effects of MSG continues, it’s important to note that naturally occurring MSG is generally considered safe and is not associated with the same concerns as its synthetic counterpart.

Seaweeds and Sea Vegetables

Seaweeds and sea vegetables, such as nori, kelp, and kombu, are rich in naturally occurring MSG. These nutrient-dense foods are not only a great source of umami flavor but also provide essential minerals and vitamins. Including seaweeds in your diet can add depth and complexity to your dishes while offering various health benefits.

Tomatoes and Tomato-Based Products

Tomatoes are another natural source of MSG. Whether you’re enjoying a fresh tomato salad, a tomato-based pasta sauce, or a flavorful salsa, you’re getting a dose of umami. Tomatoes are also packed with antioxidants, vitamins, and lycopene, which have been linked to numerous health benefits.

Aged Cheeses

If you’re a cheese lover, you’ll be delighted to know that aged cheeses like Parmesan, Roquefort, and Gouda contain naturally occurring MSG. These cheeses undergo a fermentation process that enhances their flavor and creates that irresistible umami taste. Remember to enjoy them in moderation due to their higher fat and sodium content.


Mushrooms, such as shiitake, oyster, and porcini, are not only a great meat substitute for vegetarians but also a fantastic source of naturally occurring MSG. Their rich, earthy flavor adds depth to various dishes. Mushrooms are also low in calories, high in fiber, and packed with nutrients, making them a nutritious addition to any meal.

Meat and Poultry

Meat and poultry, such as beef, pork, chicken, and turkey, naturally contain small amounts of MSG. When cooked, these proteins release glutamic acid, which contributes to the umami taste. However, it’s important to note that consuming excessive amounts of processed or cured meats may have additional health implications due to their high sodium and nitrate content.

Soybeans and Soy-Based Products

Soybeans and soy-based products, including tofu, tempeh, and soy sauce, are rich sources of naturally occurring MSG. These plant-based protein alternatives are not only versatile but also provide essential amino acids and other nutrients. Incorporating soy-based products into your diet can help add depth and flavor to your meals.

Fish and Seafood

Fish and seafood, such as mackerel, tuna, and shellfish, naturally contain MSG. These ocean treasures are not only rich in umami flavor but also provide essential omega-3 fatty acids, vitamins, and minerals. Including fish and seafood in your diet offers various health benefits, including supporting heart health and brain function.

Nuts and Seeds

Nuts and seeds, such as walnuts, peanuts, and sunflower seeds, are another natural source of MSG. These nutrient-dense snacks not only provide a satisfying crunch but also offer essential fatty acids, protein, and vitamins. Including a variety of nuts and seeds in your diet can contribute to overall health and well-being.

Health Implications of Consuming MSG

Monosodium glutamate (MSG) is a flavor enhancer commonly used in processed foods. While the Food and Drug Administration (FDA) has classified MSG as safe for consumption, some individuals may experience adverse reactions after consuming it. It is important to understand the potential health implications of consuming MSG.

Common reactions to MSG

Many people report experiencing symptoms such as headaches, flushing, sweating, and a feeling of general discomfort after consuming foods containing MSG. These symptoms, commonly known as “Chinese Restaurant Syndrome,” are typically short-lived and not life-threatening. However, individuals who are sensitive to MSG may choose to avoid foods that contain it.

The link between MSG and migraines

Research has suggested a potential link between MSG consumption and migraines. Some individuals with a history of migraines may be more susceptible to experiencing migraines after consuming foods containing MSG. While the mechanism behind this link is not fully understood, it is believed that MSG may trigger migraines by affecting neurotransmitters in the brain. If you suffer from migraines, it may be worth considering reducing your intake of foods containing MSG.

MSG and its impact on blood pressure

There have been studies examining the effects of MSG on blood pressure. While some early research suggested that MSG may cause a temporary increase in blood pressure, more recent studies have failed to find a significant association between MSG consumption and blood pressure levels. It is worth noting that individuals with pre-existing hypertension may want to monitor their intake of foods containing MSG and consult with their healthcare provider if they have concerns.

Although there are reports of potential adverse reactions to MSG, it is important to note that the majority of people can consume MSG without experiencing any negative effects. As with any food ingredient, moderation is key. If you are concerned about the potential health implications of consuming MSG, it may be helpful to read food labels carefully and make informed choices about your diet. Remember to consult with a healthcare professional if you have any specific concerns or medical conditions.
