About MSG
Using monosodium glutamate (or MSG) as a food additive continues to be a major health safety concern. Attention centers on the adverse symptoms from MSG intake. Public concerns include the possibility of hidden MSG ingredients in food labels in the market. The clamor for a better labeling regulation by the Food and Drug Administration (FDA) to include MSG's other forms remains unheeded.

History
-
The discovery of MSG started with the isolation of glutamic acid by a German chemist in the late 1860s. It wasn't until 1908 that its flavor-enhancing potential was tapped. A Japanese professor associated the savory taste it created with that of tomatoes, meat and cheese. American households started using MSG in the 1940s, but public attention shifted to safety concerns some 20 years later due to some adverse reactions toward glutamates.
Significance
-
MSG is a common food additive that enhances the flavor. It is glutamic acid in its manufactured state, derived from fermenting molasses and food starch. Glutamic acid is a form of amino acid in our bodies. Combined with protein, it is present in many living cells. MSG can simulate meat-like flavors when glutamate receptors sense it in our tongues.
The question of MSG's safety emerged after adverse reactions were reported following instances of MSG intake. The FDA maintains its classification of MSG as "generally recognized as safe," but it recognizes that uncontrolled amounts can lead to unhealthy results. Consumers continue to be advised by information disseminated by advocacy groups.

Effects of MSG Intake
-
Some people who are MSG-sensitive can suffer from headaches, nausea, chest pains, drowsiness and rapid heartbeats. For those with higher tolerance, side effects can occur an hour after taking at least 3 grams of MSG on an empty stomach. Advocacy groups argue that life-threatening effects occur with accumulated amounts of MSG through the years, including Alzheimer's disease, obesity and other chronic illnesses.
Considerations
-
FDA regulation states that food with MSG must be labeled as such. No action has been made on consumer petitions to create a more extensive listing that includes MSG in its many forms. Some food label names that contain MSG include hydrolyzed protein, calcium caseinate, gelatin, yeast nutrient and monopotassium glutamate.
Prevention/Solution to MSG Sensitivity
-
To avoid MSG's adverse symptoms, consumers should reading labels to avoid food items with MSG. Stay away from processed food and drinks; as much as possible, eat food prepared in one's own kitchen. Keep to the healthy habit of washing fruits and vegetables before cooking or eating.
