MSG, or monosodium glutamate, is a sodium salt of glutamic acid. As a food additive, it’s used to enhance flavor. It’s found in many seasonings, sauces, salad dressings and prepared foods; it’s also often used in fast food preparation. Side effects associated with MSG consumption include a burning feeling in the chest, arms and face, as well as chest pains, headache, fatigue, heart palpitations and nausea. The FDA does not require manufacturers who use MSG in their products to list it as an ingredient. Here’s a list of foods that often contain MSG; please keep in mind that not all products from these companies contain MSG, so check with the manufacturers to be sure.

Popular chain restaurants, like Applebee’s, are also known to use MSG in many of their products.

If you’d like to avoid MSG at your favorite restaurants, check that restaurant’s food allergy guide online, and avoid using spices, sauces or sweeteners at that restaurant. Many restaurants will provide MSG free sweeteners, spices and sauces if you ask.
