MSG is a kind of compound that can replace table salt enhancing the flavor of food that it has been put on and reduces sodium intake because it contains only one third of the amount of sodium that salt table contains. Originally made from seaweed, MSG is now manufactured industrially and added to many canned vegetables, soups and processed meats.
However, The Food and Drug Administration classifies MSG as a generally safe food ingredient but some people may be sensitive to it, developing neurological symptoms that make up MSG Symptom Complex, also called Chinese Restaurant Syndrome because of the high MSG content of many Asian dishes.
This Syndrome may include facial pressure, chest pain, numbness, headache, flushing and sweating. Although research has failed to identify a definite link between MSG and the syndrome, Mayo Clinic experts suggest that a small percentage of people may be MSG-sensitive and experience these symptoms after ingesting it.
So in the conclusion, if you are sensitive to MSG beware of the food you eat and make sure it doesn't contain MSG, you can do that by reading the ingredients label or contacing the manufacturer.
Have a nice day !
