What is Monosodium Glutamate (MSG)?
Monosodium glutamate, or MSG, is a sodium salt derived from glutamic acid, an amino acid found naturally in many foods. It is widely used as a food additive to enhance savory, or "umami," flavors. MSG is created by fermenting starches, sugar beets, or sugar cane. While the U.S. Food and Drug Administration (FDA) and other food safety organizations have recognized it as safe for the general population, it remains a controversial ingredient for some. In certain individuals, consuming large doses of MSG may lead to adverse effects like headaches or flushing.
Popular Chip Brands with Added MSG
Many of the most recognizable and flavorful chip varieties on the market contain added MSG. The additive boosts the umami taste, making the savory and salty flavors more intense and appealing. A simple glance at the ingredients list can reveal its presence. Some common examples include:
- Doritos: Many flavored varieties of Doritos, such as the classic Nacho Cheese, contain MSG. Its inclusion is part of the formula designed to make the chips highly addictive and flavorful.
- Pringles: Several Pringles flavors, particularly savory options like Sour Cream & Onion, list monosodium glutamate as an ingredient. The unique, stackable chips utilize various additives to achieve their distinct taste.
- Funyuns: As a savory, onion-flavored snack, Funyuns also rely on MSG for their flavor profile. Ingredients listings for Funyuns consistently show monosodium glutamate.
- Flavored Lay's: While many of Lay's simpler, plain chip varieties do not contain added MSG, certain seasoned options may. For example, some Sour Cream & Onion flavors include it for flavor enhancement. However, the brand also offers MSG-free options.
It is important to remember that manufacturers may alter ingredients, and different flavors of the same brand can have different compositions. Reading the nutrition label is always the most reliable way to check for MSG.
How to Identify MSG and Related Ingredients
To navigate the snack aisle effectively, knowing how to spot MSG on a label is crucial. Under FDA regulations, MSG must be explicitly listed by its common name, "monosodium glutamate". However, there are other ingredients that contain free glutamates and can produce a similar flavor-enhancing effect. These are often used as alternatives or in combination with MSG.
Key ingredients to look for on labels include:
- Autolyzed yeast extract: A product of autolysis (cell self-digestion) in yeast, this ingredient is rich in free glutamate.
- Hydrolyzed protein (vegetable or soy): The hydrolysis process breaks down proteins into amino acids, including glutamic acid.
- Disodium guanylate and disodium inosinate: These ingredients are flavor enhancers that work synergistically with MSG to boost the umami flavor. If you see these on an ingredients list, MSG is often present as well, or you will experience a similar effect.
- Yeast extract: Often listed under this general term, it is another common source of free glutamates.
Navigating the Chip Aisle: MSG-Free Alternatives
For those who want to avoid added MSG, there are many options available. The general rule of thumb is that simpler, less-seasoned chips are less likely to contain added flavor enhancers. Plain, salted potato chips, for example, often contain only potatoes, oil, and salt. Several brands have also made commitments to offer MSG-free products, such as Old Dutch Foods.
The Role of Natural Glutamates
It's worth noting that some ingredients naturally contain glutamates, but this is different from added MSG. Ingredients like tomato powder, yeast extract, and certain spices in a seasoning blend can contribute to the umami flavor without the presence of the specific monosodium glutamate additive. This is why reading the label carefully is important, especially for those sensitive to all forms of free glutamates.

Conclusion: Making Informed Nutritional Choices
Ultimately, understanding the contents of your snack foods is a powerful tool for maintaining a nutrition diet that aligns with your personal health goals. For those wanting to avoid added MSG, the solution is straightforward: read the ingredients label on every bag. By learning to recognize not just monosodium glutamate but also the various yeast extracts and hydrolyzed proteins that can contain free glutamates, you can make smarter choices at the grocery store. Remember that while added MSG is generally considered safe, a diet focused on whole, unprocessed foods is always a healthier path. Making conscious decisions about your snack food purchases is a great way to take control of your nutritional intake.
