. Many people link headaches, flushing, poor attention and other symptoms, as well as diseases like fibromyalgia, to MSG intake.
Is it bad for you? Monosodium glutamate (MSG) is a flavor enhancer commonly added to Chinese food, canned vegetables, soups and processed meats. The Food and Drug Administration (FDA) has classified MSG as a food ingredient that’s “generally recognized as safe,” but its use remains controversial.
Monosodium glutamate (MSG): Is it harmful? – Mayo Clinic What is MSG? Is it bad for you? Monosodium glutamate (MSG) is a flavor enhancer commonly added to Chinese food, canned vegetables, soups and processed meats.
Glutamic acid functions as a neurotransmitter in your brain. It is an excitatory neurotransmitter, meaning that it stimulates nerve cells in order to relay its signal. Some people claim that MSG leads to excessive glutamate in the brain and excessive stimulation of nerve cells.
For this reason, when MSG is added to food, the FDA requires that it be listed on the label. MSG has been used as a food additive for decades. Over the years, the FDA has received many anecdotal reports of adverse reactions to foods containing MSG. These reactions — known as MSG symptom complex — include: Headache.
What are the symptoms of MSG?
MSG has been used as a food additive for decades. Over the years, the FDA has received many anecdotal reports of adverse reactions to foods containing MSG. These reactions — known as MSG symptom complex — include: 1 Headache 2 Flushing 3 Sweating 4 Facial pressure or tightness 5 Numbness, tingling or burning in the face, neck and other areas 6 Rapid, fluttering heartbeats (heart palpitations) 7 Chest pain 8 Nausea 9 Weakness
Chest pain. Nausea. Weakness. However, researchers have found no definitive evidence of a link between MSG and these symptoms. Researchers acknowledge, though, that a small percentage of people may have short-term reactions to MSG. Symptoms are usually mild and don’t require treatment.

Why is MSG better than other types of food?
However, the glutamic acid in MSG may be easier to absorb because it isn’t bound inside big protein molecules that your body needs to break down . MSG enhances the savory, meaty umami flavor of foods. Umami is the fifth basic taste, along with salty, sour, bitter and sweet ( 2 ).
What Is MSG? MSG is short for monosodium glutamate. It is a common food additive — with the e-number E621 — that is used to enhance flavor. MSG is derived from the amino acid glutamate, or glutamic acid, which is one of the most abundant amino acids in nature. Glutamic acid is a non-essential amino acid, meaning that your body can produce it.
This additive is popular in Asian cooking and used in various processed foods in the West. The average daily intake of MSG is 0.55–0.58 grams in the US and UK and 1.2–1.7 grams in Japan and Korea ( 3 ). MSG is the sodium salt of glutamic acid, an amino acid found in your body and most foods.
However, dietary glutamate should have little to no effect on your brain, as it cannot cross the blood-brain barrier in large amounts ( 6. Trusted Source. ). Overall, there is no compelling evidence that MSG acts as an excitotoxin when consumed in normal amounts.
Fear of MSG dates as far back as 1969, when a study found that injecting large doses of MSG into newborn mice caused harmful neurological effects ( 4. Trusted Source. ). Since then, books like Russell Blaylock’s “Excitotoxins: The Taste That Kills” have kept this fear of MSG alive.
Eating filling foods should reduce your calorie intake, which may aid weight loss. Some evidence suggests that MSG may help you feel full. Studies note that people who consume soups flavored with MSG eat fewer calories at subsequent meals ( 14.
Some People May Be Sensitive. Some people may experience adverse effects from consuming MSG. This condition is called MSG symptom complex. In one study, people with self-reported MSG sensitivity consumed either 5 grams of MSG or a placebo — 36.1% reported reactions with MSG compared to 24.6% with a placebo ( 7 ).
What is MSG in food?
Monosodium glutamate (MSG) is a controversial food additive that people use to enhance flavor. Many people associate it with Asian cuisine, though it is an ingredient in a variety of foods, including processed meats, soups, and fast food. Historically, many people have believed that MSG can lead to various health conditions.
According to one 2017 study, people have been using MSG to season their food for over 100 years. Some people in Japanese cultures consider MSG, or umami, to be one of the five basic tastes. Many dishes featured in Japanese, Chinese, and South Asian cuisine use MSG.
Since a typical serving of food with MSG contains only 0.5 g of MSG, reactions are unlikely following typical meals.
In 1908 . Trusted Source. , a professor at the University of Tokyo in Japan extracted MSG for the first time from seaweed. Manufacturers now typically produce it by fermenting starch, sugar cane, or molasses. This fermentation process is similar to the method that people use to make vinegar, wine, and yogurt.
The FDA. Trusted Source. classifies MSG as generally safe. There is not enough evidence to support a link between MSG consumption and the adverse reactions that people have reported. Researchers cannot conclusively say that MSG has caused the reactions in these reports.
For example, the MSG damaged the hypothalamus, which plays a crucial role in maintaining homeostasis. However, it is not possible to compare the effects of injecting large amounts of MSG into newborn mice with the effects of humans ingesting small amounts of MSG from food into their gastrointestinal tract.
Alleged hypersensitivities to MSG are only based on people’s reports. According to the 2019 review above, there is not enough solid evidence to confirm that a hypersensitivity to MS G exists. The review called for more studies into sensitivities involving both naturally occurring MSG and added MSG.
