Some people still hang on to the flawed science and xenophobic belief that MSG is bad.
Yeah it is a hard one to shake. My mom was not the least bit xenophobic but she did get serious headaches from MSG. But only when she knew she was eating it. And she loved tomatoes too! I miss her dearly, and she was actually quite sharp, but she would not let go of the MSG thing despite ample evidence to contradict her belief.
Certainly there were restaurants trying to sell you the "5-Hour Energy" equivalent of MSG and some cuisines tend to get closer to doing that naturally. But also you shouldn't directly or indirectly blame the people that make that food for you, just as it is silly to blame all coffee shops for the caffeine headaches and migraines you sometimes get if you don't watch how much coffee you are drinking.
