Question

what is MSG and why it is harmful to eat in which food it is used...

Answer 1

Monosodium glutamate (MSG) is a flavor enhancer commonly added to Chinese food, canned vegetables, soups and processed meats. The Food and Drug Administration (FDA) has classified MSG as a food ingredient that's "generally recognized as safe," but its use remains controversial. For this reason, when MSG is added to food, the FDA requires that it be listed on the label.

MSG has been used as a food additive for decades. Over the years, the FDA has received many anecdotal reports of adverse reactions to foods containing MSG. These reactions — known as MSG symptom complex — include:

Headache
Flushing
Sweating
Facial pressure or tightness
Numbness, tingling or burning in the face, neck and other areas
Rapid, fluttering heartbeats (heart palpitations)
Chest pain
Nausea
Weakness
