I am not game to even contemplate eating anything with 635, as once I knew what my reaction to MSG was like, I found out the hard way, and saw the flavour enhancer 635, so I thought it may be OK. My face swelled up, I developed a rash all over my face and neck, and consequently all the skin peeled off my tongue, inside of my lips and gums. You have never seen such a mess!! At least I didn't have to go through what these little kids had to suffer and their poor parents. I just couldn't eat anything much for a few days!! – reader by email.
