MSG in Everyday Life and Beyond
MSG’s presence extends beyond the kitchen. It can be found in:
- Processed Foods: MSG is a common ingredient in many processed foods, including canned soups, snacks, and packaged meals.
- Restaurant Dishes: Some restaurants use MSG to enhance the flavor of their dishes, although it’s not always explicitly disclosed on menus.
- Pharmaceuticals: MSG is sometimes used as a pharmaceutical excipientPharmaceutical excipients, while often overlooked, are indispensable components of nearly every medication we take. These substances, though not the active therapeutic agents themselves, play crucial roles in ensuring the safety, efficacy, and delivery of medicines. They are the unsung heroes… Read More, a substance that aids in the formulation and delivery of medications.
MSG and the Body: A Question of Safety
While MSG is generally recognized as safe by regulatory agencies like the U.S. Food and Drug Administration (FDA), its safety has been a subject of debate for decades. Some individuals report experiencing symptoms like headaches, flushing, and sweating after consuming MSG, a phenomenon often referred to as “MSG symptom complex.”
However, scientific studies investigating these claims have produced mixed results. Some studies have found no significant link between MSG and adverse reactions, while others have reported mild symptoms in a small percentage of individuals.

Research on MSG: Separating Fact from Fiction
Numerous studies have explored the potential health effects of MSG, but the results have been inconclusive. A comprehensive review published in the Journal of Headache and Pain in 2016 concluded that MSG is not a significant trigger for headaches in the general population, although a small subset of individuals may experience mild, transient symptoms.
Another review published in Food and Chemical Toxicology in 2017 examined the safety of MSG and concluded that it is safe for consumption at levels typically used in foods. However, the authors acknowledged the need for more research on potential long-termChronic simply means “happening over a long period of time” or “of long duration.” Imagine a situation that keeps going on and on, unlike something short-lived. • Other Names: You might not encounter many other terms for chronic in everyday… Read More effects and interactions with other dietary components.
