Of course there is evidence, that is why we are having this discussion. In addition to the evidence that there exists a very small minority of people who are sensitive to MSG, there exists a large industry that is dependent upon the availability of an inexpensive, effective flavour enhancer. That industry has an interest in discrediting the ill effects of MSG, just as the petrochemical industry had an interest in discrediting the effects of CO2 in the atmosphere and the tobacco industry had an interest in discrediting the effects of smoking.

I must be mistaken because based on the article, I thought we were having this discussion because there is no evidence.

The article mentions right in the beginning that studies have shown evidence for a connection between MSG intake and onset of symptoms.
