Is Monosodium Glutamate (MSG) Actually Unhealthy?

Monosodium glutamate or MSG, has been a commonly used taste enhancer for about a century. It is a typical culinary ingredient in soups, canned vegetables and other processed foods. However, MSG has been perceived as a harmful component for a long time, and more recent studies cast doubt on the veracity of the claims made about its harmful effects on human health.

In this write-up, we will learn about monosodium glutamate and explore its impact on a person’s body. Moreover, we’ll also know about some foods that contain MSG. So, let’s start by knowing what Monosodium glutamate is.

What is MSG?

Monosodium glutamate is abbreviated as MSG. L-glutamic acid, which is found naturally in various food items, is the source of this taste enhancer. Since your body can manufacture L-glutamic acid on its own and doesn’t require it from food, it is considered a nonessential amino acid.

MSG is a crystalline, white and odourless powder frequently added to meals. It goes under the name E621 in the food sector and readily dissolves in water, splitting into free glutamate and sodium. Carbs like sugar cane, sugar beet and molasses are fermented to make it. MSG and glutamic acid that occur naturally in a variety of foods are chemically similar. But, when put differently, your body cannot differentiate between the two types.

Is MSG Bad for You?

For many years, MSG was thought to be a harmful component. Newer studies, however, doubt the integrity of its alleged detrimental effects on human health. FDA has categorised MSG as a generally regarded safe component. 

Because of this, the Food and Drugs Administration mandates that MSG must be disclosed on the label whenever it is added to food. For a long time, MSG has been added to food. The FDA has received several reports during this period regarding responses that people have linked to MSG-containing foods. These reactions are called MSG symptom complexes. Due to these reactions,  MSG side effects can occur, which include:

• Headache
• Sweating
• Face pressure or tightness
• Flushing
• Quick and fluttering heartbeats
• Tingling or burning in the face, neck and other areas
• Lack of feeling (numbness)
• Chest pain
• Feeling sick (nausea)
• Weakness

However, researchers have found no clear proof of a link between MSG and these symptoms. They have found that rare individuals may experience transient responses to MSG. Most symptoms are not severe enough to require medical attention, and you can avoid a response by avoiding MSG foods.

Foods That Contain MSG

MSG is naturally present in certain foods, such as tomatoes and cheese. Meanwhile, processed snacks, instant noodles and pre-packaged sauces often use MSG to add a savoury flavour. While some myths suggest adverse effects, scientific consensus, including studies by reputable health organisations, finds MSG safe for most people. Enjoying a varied diet with awareness of MSG in processed foods allows for a balanced culinary experience. Remember, moderation is key in savouring the diverse flavours that MSG can bring to your plate. Here are some examples of foods that contain MSG:

• Hot Dogs and Sausages
• Canned Soups
• Instant Noodles
• Snack Foods
• Seasoning Mixes
• Fast Food
• Frozen Meals
• Sauces and Dressings
• Processed Cheese
• Asian Dishes

Remember, not all processed foods are MSG foods, and they’re regulated in many places. Always check food labels if you’re keeping an eye out for MSG.

Conclusion

In conclusion, Monosodium Glutamate is a flavour enhancer widely used for roughly 100 years. While some people may be more sensitive to MSG than others, experts generally consider it safe, especially in smaller doses. MSG is derived from L-glutamic acid, which is naturally present in many foods. The Food and Drug Administration has classified MSG as a food ingredient generally considered safe. Other health authorities agree with this, including the World Health Organisation, Health Canada and the Federation of American Societies for Experimental Biology.
