I think most of us know not to put this stuff in our bodies by now ...
A piece of spammy mail I got:
>Long winded email
MSG isn't good for you, that much is fact. But that email is about 98% bullshit.
I get the same impression. I have not done any research, other than as it may apply to myself and my kids. We avoid it like poison in this house.
As we all know, bullshit is often backed by more plausible or, at least, more baffling bullshit.
