Has MSG gotten a bad rap?
I’ve personally never had a problem with it. I used to keep it on hand, in fact, though I haven’t used it in decades.
[Update a few minutes later, after reading the whole thing]:
As Brendan Nyhan, a Dartmouth professor who has researched how to influence attitudes about vaccines, pointed out to me in an email, it’s hard for people to change their minds about personal health issues because it contradicts what they have perceived to experience in the past. “People who felt bad after eating Chinese food in the past may have blamed MSG … and thus resist information they encounter later about its actual effects,” he said. This may be the result of the availability heuristic, where people make judgments using the easiest information available, rather than looking for alternative explanations.
This could also explain peoples’ resistance to accepting new ideas about nutrition, when (e.g.) they’ve been told for decades to avoid fat.

I’m pretty confident in my allergy to tree nuts. Even if no one tells me, I can tell when I’ve had them.
