Children should stay away from MSG

MSG or monosodium glutamate is excitatory neurotransmitter. It is used as a taste enhancer. As such, food will taste better if MSG is added. However, this excitotoxin will damage the brain cells by over-stimulating them. In adults, the blood brain barrier with limit the entry of substances into the brain.

In children, the brains are not well-developed yet. Neither is the blood brain barrier. This explains why children should not consume too much food which contains MSG as their brains are four times more sensitive to MSG.
