Is MSG bad for you?
The potential ill-effects caused by MSG were first described in a medical journal as ‘Chinese Restaurant Syndrome'. Symptoms including numbness and palpitations were reported shortly after visiting a Chinese restaurant. Such claims have never been specifically linked to MSG however, and could be due to common allergies to ingredients like peanuts and shellfish.
MSG has been linked to many conditions including migraines, asthma, depression and Alzheimer's, but has never been isolated as a cause. Huge amounts of MSG have been fed to humans without causing ill-effects, and MSG is considered a safe additive by every government which tests these things.
Feeding excess glutamate to rats has caused some problems, including retinal damage, but only after feeding them massive amounts of MSG, much more than would ever be consumed by a human.
An ‘international team of experts' met in early 2007 to review the current knowledge of MSG safety, and concluded that MSG was ‘harmless for the whole population' (Consensus Meeting on monosodium glutamate, published in the European Journal of Clinical Nutrition). They agreed that there was no new evidence (since their last meeting in 1997) that certain individuals reacted badly to MSG.
Glutamate is an important chemical in the brain, and there is the potential for neurological effects if very high levels of glutamate reached the brain. However, the ‘blood-brain' barrier effectively prevents this, and problems in rats have only occurred if massive amounts of MSG are given. The group did comment that people with some illnesses have a compromised blood-brain barrier, and the effect of this on brain glutamate levels is unknown.
All the evidence suggests that consuming normal amounts of added glutamate cause no ill-effects. However, it is possible that certain people could be particularly sensitive to glutamate, and if problems are linked to MSG-containing foods they may want to cut their intake of these foods.
