Lots of food stuff may not really contain MSG but some other
flavor enhancer.
If you buy a snack, read the labels, all sorts of additives and
enhancers.
Or a bottle of ketchup, any ketchup, especially the more
complicated ketchup for cooking. It contains all sorts of additives
and enhancers.
So thats why I dont really care about MSG but all kinds of
unnatural things, including processed things such as "sugar" which
is supposedly also bad.
