MSG (monosodium glutamate) is a food additive commonly used to enhance the flavour of savoury dishes. Its umami flavour comes from sodium and glutamic acid (the same acid found in tomatoes, parmesan cheese, and even human breast milk).
The ‘is MSG healthy?’ debate has been raging since the sixties, when it became known as ‘Chinese Restaurant Syndrome’ after a doctor in the US wrote a letter describing his symptoms after consuming a large Chinese restaurant meal. Symptoms include headaches, flushing and sweating, numbness and tingling in the back of the neck, palpitations and feeling sick. It went viral and the rest they say, is history.
While these symptoms are generally mild and short-lived, even though studies over the years have been inconclusive. (Over in the US, the Food and Drug Administration (FDA) considers MSG to be safe for consumption.)
It is generally agreed that some people may be more sensitive to MSG than others. If you experience any adverse reactions after consuming foods containing MSG, it may be best to avoid it in the future or limit your intake. If you have concerns or experience symptoms, always consult your healthcare provider.
