Does McDonald's add MSG to its menu?
For customers in the United States, McDonald's officially states that it does not add monosodium glutamate (MSG) to the products on its national menu. The company has made a public effort to remove artificial preservatives and other controversial ingredients from its standard offerings over the years. This commitment to simpler ingredients extends to its core menu items, including hamburgers, cheeseburgers, and fries. For example, the company notes that its classic beef patties contain only 100% USDA-inspected beef with a pinch of salt and pepper added on the grill. The same transparency applies to its fries in the U.S., where the official ingredient list does not include MSG.
The history of MSG in McDonald's test items
While the national menu has remained free of added MSG, the situation became more complex during the "chicken sandwich wars" of early 2020. In an effort to compete with popular chicken sandwiches from rivals like Chick-fil-A and Popeyes (both of which use MSG), McDonald's tested new crispy chicken sandwiches in select U.S. markets. Company statements confirmed that these test sandwiches did contain MSG. Additionally, other regional test items and menu additions in places like Hawaii and Georgia have been found to contain added MSG. This highlights a crucial distinction: a menu item may or may not contain MSG depending on its location and availability. The company noted that feedback from these tests would inform future decisions, demonstrating that consumer perception is a factor in ingredient choices.
The difference between added and naturally occurring MSG
The key to understanding the MSG debate lies in the distinction between adding pure MSG as a flavor enhancer and the presence of naturally occurring glutamate. Glutamate is an amino acid found in many foods, including tomatoes, aged cheeses, and proteins. Ingredients like hydrolyzed vegetable protein or autolyzed yeast extract, which contain naturally occurring glutamate, are sometimes used by McDonald's and other food manufacturers. When these ingredients are listed, they do not have to be explicitly labeled as "MSG." While the FDA considers the glutamate from both sources to be chemically identical and processed the same way by the human body, this can be misleading for customers who are trying to avoid the additive. A list of glutamate-containing ingredients includes:
- Autolyzed yeast extract
- Hydrolyzed vegetable protein
- Protein isolate
- Yeast extract
- Soy sauce
International menu variations
Another important factor is that McDonald's menu and ingredient policies vary significantly by country. What is true for the U.S. national menu may not apply elsewhere. For instance, the McDonald's UK website states explicitly that no MSG is used in its food sold in the UK. In contrast, McDonald's Singapore lists several items, including the McSpicy and McChicken, as containing MSG. Customers traveling internationally should always check the local ingredient information provided by McDonald's in that country. This is especially important for those with MSG sensitivity.
McDonald's MSG policies vs. competitors
To put McDonald's policies in context, a comparison with other fast-food giants is helpful. The 2020 crispy chicken sandwich tests were a direct response to the popularity of chicken items at rival chains, which often use MSG to achieve their signature savory flavor profiles. Here is a brief comparison table:
| Feature | McDonald's (U.S. National Menu) | Chick-fil-A | Popeyes | 
|---|---|---|---|
| Added MSG? | No | Yes | Yes | 
| Chicken Sandwich | (Current) No added MSG | (Classic) Contains MSG | (Classic) Contains MSG | 
| Transparency | Publicly available ingredient list | Ingredient information available | Ingredient information available | 
Conclusion: The complexities of MSG in McDonald's
The question of whether is MSG used in McDonald's is not a simple yes or no answer. While the company has made significant strides in removing added MSG and artificial ingredients from its core U.S. national menu, the story is more nuanced. Regional test products and international menu items may contain the additive, and customers must also be aware of naturally occurring glutamate in ingredients like yeast extract and hydrolyzed protein. This highlights the importance of checking local ingredient lists, especially for individuals with sensitivities or those who prefer to avoid the additive.
