MSG Found To Injure Retina,

Damage Eyesight

TOKYO (ANI) -- The controversial taste-enhancer Monosodium glutamate (MSG)

is

once again in the centre of a debate. A recent research has found it to

damage

people's eyesight.

 

Scientists found that eating large amounts of MSG, used to flavour oriental

and

processed foods, can injure the retina and lead to vision loss.

 

Rats fed diets high in MSG in Japan developed thinner retinas and began to

go

blind. Glutamate is an amino acid which acts as a neurotransmitter, a

chemical

that sends signals between nerve cells.

 

Previous research has already shown that it causes nerve damage when

injected

directly into the eye. But the Japanese study at Hirosaki University was the

first to show that eye damage can be caused by eating food containing MSG,

says

a report in Sydney Morning Herald.

 

Rats were fed three different diets for six months, containing either high

or

moderate amounts of MSG, or none. In animals on the high MSG diet, some

retinal

nerve layers thinned by as much as 75 per cent.

 

Tests to measure retinal response to light showed that the rats' vision was

impaired. Those on the moderate diet also suffered damage, but to a lesser

extent.

 

Research, also showed high concentrations of MSG in the vitreous fluid which

bathes the retina. MSG bound to molecules on retinal cells and destroyed

them,

causing secondary reactions that reduced the ability of the remaining cells

to

relay electrical signals, the report added. (ANI)

I would be very interested to find out whether the rats fed a

" high " dose of MSG were fed it in quantities likely to be eaten by

humans eating real MSG spiced foods, or if they were fed many many

times what a person would normally eat. Also wondering how " less "

was in the diet with less MSG, and how much eye damage that quantity

produced. If anyone sees an URL with a site with more info, I'd

appreciate it.
