Have you ever seen the following sign in a chinese restaurant or your favourite potato chips and wondered what the fuss was all about? Yes? Read ahead please...
"NO ADDED MSG"
WHAT IS MSG?
Mono Sodium Glutamate is a sodium salt of glutamate. Glutamate is found in milk, meat, fish, mushroom, tomato and even produced by our own bodies. MSG was found to increase the taste of food and was patented by Ajinomoto Corporation of Japan. Hence the common name, Ajinomoto.
THE FIFTH TASTE?
Bet you can name the four basic tastes - sweet, sour, bitter and salty. Would you be surprised if told that there is a fifth taste? Umami is the so called fifth taste. Forecast as one of the leading food trends of 2010, it has been described as a meaty taste.
MSG is a flavour enhancer and adds to the Umami-ness of food. Its commonly added to Chinese food.
HOW IS MSG PREPARED?
MSG is obtained by the fermentation of starch or sugar cane.
CHINESE RESTAURANT SYNDROME?
Few people have reporting sensitivity to MSG. Soon after a Chinese meal, they experienced the following :
•Headache
•Warmth
•Sweating
•Numbness, tingling or burning in face and neck
•Rapid heartbeats
•Chest pain
•Vomiting
•Weakness
However scientific studies in the same people who thought they were sensitive failed to demonstrate any side effects after they were given food flavoured with MSG.
It is theorised that allergy to other ingredients such as prawns, spices and herbs may have been responsible for the symptoms.
POTENTIAL CONCERNS?
A 2008 study suggested link between MSG and obesity but it was refuted by another study done in 2010.
If you are prone to asthma or wheezing attacks, you may want to avoid MSG.
ANY HEALTH BENEFITS?
Common salt contains sodium. Sodium should be restricted in people who have high blood pressure, heart failure, liver and kidney diseases. MSG contains only 1/3rd sodium of common salt . It can help to reduce the total sodium in a recipe without losing flavour. So it can be a safer alternative to the above people.
IS IT SAFE IN KIDS?
In studies with baby rats, High levels of Glutamate (more than 10 times the allowed amount) caused brain damage and blindness. An important concern is the potential harm in infants whose blood brain barrier is not fully developed. MSG is safe for older children. In fact, even breast milk contains glutamate.
SUMMING UP
Scientific studies so far have concluded that MSG is safe. However you need to avoid it
1) If you have demonstrated symptoms after a meal flavoured with MSG
3) If you are prone to asthma attacks.
