In the offical
Simpsons Comic (edition with
The Homer Show on the front cover), the cover story contains a scene where
Homer goes into the
Kwik-E-Mart and buys lots of stuff. One of the packets of 'stuff' is called "Monosodium Glutimunchies". Obviously doesn't sound too healthy.
Similiar to the episode of the Simpsons where Bart's bones have become brittle because he's been drinking refreshing "Malk" (with added Vitamin R).
