What Is MSG? Is It Bad for You?

What is MSG?

MSG or monosodium glutamate is a flavour enhancer widely used in cooking, especially in Asian cuisines and processed foods. It gives food a rich, savoury taste. It is a type of chemical compound, which is made using natural ingredients like sugarcane or starch through the fermentation process. Labelled as E621, in the food industry, MSG is a white, odourless substance that dissolves quickly in water, breaking down into sodium and free glutamate.

What is MSG made of?

MSG is made from a natural substance called glutamic acid. Glutamic acid is a type of amino acid found in foods like tomatoes, cheese, mushrooms, and seaweed.

MSG is made using the process of fermentation from carb sources like starch, sugarcane, sugar beets, or molasses.

Is MSG Naturally Found in Foods?

MSG (monosodium glutamate) itself is a food additive, but its key component, glutamate, is naturally present in foods, such as:

• Tomatoes

• Parmesan cheese and other aged cheeses

• Mushrooms

• Meats (beef)

• Chicken

• Fish

Is MSG the Same as Gluten?

Although the word “glutamate” in MSG and “gluten”, sound similar, the two are very different.

Here are the differences:

Monosodium Glutamate is a food enhancer made from glutamic acid; it does not contain gluten. On the other hand, gluten is a type of protein found in wheat, barley, and related grains. People with gluten sensitivity must avoid it.

Is MSG Safe to Eat?

You must be wondering, ‘Is Monosodium Glutamate Harmful?’ MSG, or monosodium glutamate, is considered safe by most leading health organisations, such as the US FDA, WHO, and EFSA.

Some people report mild symptoms like headaches or flushing after eating large amounts of MSG, often referred to as “Chinese Restaurant Syndrome.” However, scientific research hasn’t found a consistent link between MSG and these effects. For those managing food sensitivities, having individual health insurance can help cover consultation or diagnostic costs if symptoms persist.

What is MSG Symptom Complex?

Some people may report mild monosodium glutamate side effects after consuming large amounts of MSG, especially on an empty stomach. These side effects are known as the MSG symptom complex. Studies show they are rare, generally mild, and do not always need treatment.

Possible Symptoms of MSG Sensitivity

Common monosodium glutamate side effects or MSG symptoms include:

• Headache

• Migraine

• Flushing (warmth and redness of the face and neck)

• Sweating

• Numbness or tingling in the face, neck, or arms

• Heart palpitations

• Nausea

• Weakness or fatigue

• Chest pain (rare and usually mild)

In such cases, having health insurance may help manage any unexpected medical visits or treatments related to recurring symptoms.

Is There a Proven Link Between MSG and These Symptoms?

There is no strong scientific evidence to support the claim that MSG consistently causes these symptoms.

Extensive research, including studies reviewed by the US FDA, World Health Organization, and other global health bodies, has found that MSG is safe when consumed in normal amounts. While some people may report mild reactions, studies have not shown a reliable link.

How to Avoid MSG Reactions?

If you think you are MSG sensitive, there are a few things you can do that may prevent symptom triggers:

• Pay attention to food labels–

Steer clear of products marked monosodium glutamate (E621), hydrolysed protein, or autolysed yeast extract.

• Fresh whole foods are best –

Fresh, whole foods are a better option. Stick to fruits, vegetables, and cuts of meat that haven’t been canned or heavily processed.

• Reduce consumption of high-MSG foods –

Consumption of foods such as instant noodles, chips, canned soups, and processed meats should be reduced.

• Ask at restaurants –

When dining out, especially at Asian or fast-food restaurants, request your food to be prepared without added MSG.

• Keep portions moderate –

MSG symptoms are more likely to occur when the ingredient is consumed in large amounts. Therefore, be mindful of consuming smaller amounts of food containing it.

Conclusion

MSG is a food additive, widely used to enhance the taste of food. It has gained a reputation for causing sensitivity in some individuals. However, studies have shown that monosodium glutamate side effects can be seen in less than 1% of the total population. In most cases, these reactions are mild and temporary.

That said, it’s always wise to be prepared for unexpected health issues. Having a reliable health insurance plan ensures you receive quality medical attention in an emergency, even in those rare cases where food sensitivities may lead to severe reactions. With the right insurance plan, you and your loved ones can access the care you need without financial worries.
