MSG doesn't assist in food digestion because it is not an enzyme. My understanding of MSG is that it overexcites nervous tissues, causing intensified activity. One would guess that this would produce intensified flavour on the tongue from "over excited taste buds". It acts on you, not the food I think.

Despite reading that MSG apparently does not cross the blood brain barrier in high amounts, I cannot deny the headaches I get after eating the stuff. Sorry I do not know the thai translation for MSG, I would also like to know.
