Scientists in Japan have indicated that consuming large amounts of monosodium glutamate (MSG) may damage vision. MSG is popularly used to flavour processed and oriental foods.


Rats fed a diet high in MSG developed thinner retinas and began to go blind. Glutamate is an amino acid that acts as a neurotransmitter, a chemical that transmits signals between nerve cells.

The research was published in New Scientist magazine. To read it, click here
