Ok so I had never even heard of MSG and its 'dangers' until I started to read about Japanese and Oriental cooking. I have never experienced 'Chinese restaurant syndrome' nor have I met anyone who has. So I was very surprised to learn about it. Then once I had discovered its apparent dangers, I watch something on the good old BBC that seemed to suggest the opposite. The show was E-Numbers: An Edible Adventure and it was the first or second episode. If you can watch iPlayer, do so as it is awesome. If not I am sure someone has youtubed it already.
