MSG is monosodium glutamate. It is probably the most popular flavor enhancer throughout the globe. Discovered by Professor Kidune Ikeda of Tokyo Imperial University in the 1908, MSG has created an unhealthy reputation because of its undesirable effects on some people.
The FDA has categorized MSG as GRAS or Generally Recognized as Safe. However, monosodium glutamate (MSG) has been cited to cause migraine, insomnia, depression, anxiety and cognitive disorders. It is also linked to obesity as it can be very addicting in food. MSG can also cause palpitation, hypotension or hypertension, stomach pains, blurred vision, dizziness and even hives.
In Asian countries, MSG has remained a favorite. Interestingly, in some parts of the Philippines, MSG is also used to sedate talkative drunk individuals.
