What is Monosodium Glutamate?
Monosodium glutamate, or MSG, is a sodium salt of the common amino acid glutamic acid. It is naturally occurring in many foods and added to others to enhance their savory or umami flavor. While MSG is a popular ingredient in food manufacturing and cooking, it has been subject to controversy over potential health effects, though scientific evidence for adverse reactions in the general population is limited.

Why People Avoid Monosodium Glutamate
Some people avoid MSG due to reports of adverse reactions, often referred to as 'Chinese Restaurant Syndrome,' which can include symptoms like headache, sweating, and flushing. However, scientific studies have not consistently supported these claims. Additionally, those following a corn-free diet may avoid MSG since it can be derived from fermenting corn glucose. It is always advisable to check with the manufacturer regarding the source of MSG in specific products.
