According to new tests....
"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."
