Any food that contains the flavour enhancer MSG (monosodium glutamate) might worsen your eyesight.
In fact, a Japanese researcher went so far as to claim that it could make you blind.
Rats fed MSG suffered vision loss and had thinner retinas than those not given the flavouring, he discovered.
This is not the first scare about MSG, found extensively in Chinese food. The American drugs agency, the Food and Drug Administration, is also concerned about MSG’s effects on the nervous system.
The Japanese research team pointed out that a very moderate intake of MSG should not impair vision, although exactly what is moderate is still uncertain.
