Monosodium glutamate (MSG) is a widely used food additive
MSG is particularly prevalent in fast food, especially Chinese food, where it is associated with "Chinese restaurant syndrome", a condition characterised by itching, headache, hives, throat irritation, swelling, and belly pain. However, it is also added to a variety of other food products, including meat products, frozen meals, chips, and canned soups.
While MSG is generally recognised as safe by the FDA, there are controversies and public fears surrounding its use. Some people choose to avoid it due to fears of adverse health effects, and self-ascribed sensitivity to MSG has been questioned. However, according to Harvard University, various scientific sources have repeatedly confirmed that MSG is safe when consumed at ordinary levels.
Parmesan cheese is one of the food products that naturally contain MSG. Other natural sources of MSG include tomatoes, dried mushrooms, some fruits and vegetables, and human breast milk.

Parmesan is a natural source of glutamate
Monosodium glutamate (MSG) is a sodium salt derived from glutamic acid, an amino acid that is both naturally occurring and synthesized. Glutamate is found in many proteins and is produced in the human body. It is also present in various natural food sources, including Parmesan cheese.
Parmesan cheese is known for its savoury flavour, which is attributed to its high glutamate content. Glutamate is responsible for the umami taste, often described as the fifth taste that makes things taste better. It is no wonder that Parmesan is often used to enhance the flavour of dishes.
While MSG is a widely used food additive, particularly in processed foods, it is distinct from naturally occurring glutamate in foods like Parmesan cheese. The FDA has classified MSG as "generally recognized as safe" (GRAS), but it remains controversial due to concerns about potential adverse health effects. However, studies have repeatedly confirmed that MSG is safe when consumed at ordinary levels.
Naturally occurring glutamate, such as that found in Parmesan cheese, is distinct from the added MSG in processed foods. The human body metabolizes both types of glutamate using the same processes, but the glutamic acid in MSG may be more easily absorbed due to the absence of protecting protein molecules.
In summary, Parmesan cheese is a natural source of glutamate, contributing to its savoury flavour. While MSG and natural glutamate are similar, there are differences in their sources and absorption rates. The controversy surrounding MSG has led to ongoing debates about its safety, but studies suggest that it is safe when consumed in ordinary amounts. Understanding the distinction between natural glutamate and MSG is essential when considering their effects on health and flavour.

Glutamate is an amino acid that occurs naturally in foods
Monosodium glutamate (MSG) is a sodium salt derived from glutamic acid, an amino acid that occurs naturally in many foods. It is also a widely used food additive, often employed to enhance the savoury or umami flavour of dishes.
Glutamate is an amino acid that is produced in the human body and occurs naturally in many foods. It is found in high levels in Parmesan cheese, as well as other cheeses like Roquefort, though in lesser amounts in cheddar cheese. Other natural sources of glutamate include tomatoes, dried mushrooms, some fruits and vegetables, beef bones, and even human breast milk.
The average person consumes about 11 grams of glutamate per day from natural sources and less than one gram from the additive MSG. MSG is commonly added to processed foods like potato chips, frozen meals, canned soups, and fast food, particularly in Chinese cuisine.
While MSG is generally recognized as safe by organizations like the FDA, there are controversies and concerns surrounding its use. Some people choose to avoid it due to fears of adverse health effects, and some experience sensitivity to MSG resulting in symptoms like itching, headaches, and throat irritation, known as "Chinese restaurant syndrome."
Despite the controversies, numerous studies have found MSG to be safe when consumed at ordinary levels, and it is already present in many natural, healthy foods.

FDA categorises MSG as generally recognised as safe
Monosodium glutamate (MSG) is a flavour enhancer that has been widely used for around 100 years. It is derived from L-glutamic acid, which is naturally present in many foods. MSG is found in many processed foods and is commonly known for its use in Asian cuisines, particularly Chinese food. It also occurs naturally in some foods like tomatoes, legumes, mushrooms, seaweed, and Parmesan cheese.
Despite its prevalence, MSG has a controversial reputation. The controversy surrounding MSG's safety started in 1968 with the publication of Robert Ho Man Kwok's letter titled "Chinese Restaurant Syndrome" in the New England Journal of Medicine. In his letter, Kwok described symptoms such as itching, headache, hives, throat irritation, and belly pain after eating Chinese food, which he attributed to MSG. This sparked a public backlash, but the Food and Drug Administration (FDA) did not remove MSG from their Generally Recognized as Safe (GRAS) list.
The FDA continues to categorize MSG as GRAS, meaning it is FDA-approved for use in food products. According to the FDA, for a substance to be GRAS, it must meet two criteria. Firstly, scientific data and information about the substance's use must be widely known. Secondly, there must be a consensus among qualified experts that the substance is safe under the conditions of its intended use.
Research on MSG has been conducted for decades, and scientists have not found a link between MSG and adverse health effects. Blinded studies have shown no evidence that MSG causes headaches or other feelings of discomfort when combined with food in normal concentrations. While some people may be more sensitive to MSG than others, experts generally consider it safe, especially in smaller doses.
Health authorities such as the Joint FAO/WHO Expert Committee on Food Additives (JECFA), the European Food Safety Association (EFSA), and the FDA itself agree that MSG is generally recognized as safe. These organizations have determined an acceptable daily intake (ADI) of 14 mg per pound (30 mg per kilogram) of body weight per day, which is far more than the amount typically ingested in a normal diet.

Some people avoid MSG due to adverse health effects
Monosodium glutamate (MSG) is a flavour additive that has been widely used for almost 100 years. It is derived from L-glutamic acid, a non-essential amino acid that can be produced by the human body and is naturally present in many foods. MSG is added to various processed foods, including canned vegetables, soups, and meat products, to enhance their taste. While MSG is generally recognized as safe by the FDA, some people choose to avoid it due to concerns about potential adverse health effects.
The controversy surrounding MSG and its potential health effects dates back to the 1960s when a Chinese-American doctor, Robert Ho Man Kwok, wrote about experiencing negative symptoms after consuming Chinese food. His letter sparked a wave of misinformation and led to the coining of the term "Chinese Restaurant Syndrome," which was associated with symptoms such as itching, headache, hives, throat irritation, and belly pain. However, early studies on MSG had significant flaws, and subsequent research has questioned the accuracy of its purported adverse effects.
It is important to note that the negative reputation of MSG may have been influenced by racially charged biases and xenophobic sentiments toward Chinese cuisine. Ian Mosby, a food historian, suggests that the fear of MSG in Chinese food is rooted in the United States' historical perception of Asian cuisine as "exotic," "dangerous," or "dirty." Additionally, some people may have a sensitivity to MSG, experiencing symptoms such as headaches, sluggishness, and achy limbs after consuming it. However, research has found that even those claiming sensitivity to MSG often do not exhibit any reaction when they are unaware they are consuming it.
While the accuracy of MSG's adverse health effects is questionable, some people still choose to avoid it due to individual sensitivities or personal preferences. It is essential to respect these choices and provide clear labelling on food products to ensure consumers are aware of the presence of MSG. Additionally, it is worth noting that MSG is not the only ingredient in Chinese cuisine or Asian cooking that has been subjected to scrutiny. Soy sauce, for example, is another essential flavour enhancer in Asian recipes that contain MSG and has faced similar controversies.
