Looking at those lists, it's a mine field of MSG
The only way of possible
avoidance is pure food grown and reared yourself, which is a bit problematical for most.
There was a time when MSG was not put in to foods, the question is, why do they even need to, it's not as if they did prior to doing so. Paprika, is another one, with some plain (salt flavoured) crisps/chips it's used as a colourant but it wasn't beforehand, proving that it isn't required.
