Reactions to MSG and other sources of manufactured free glutamate (MfG) are reactions to poison. They’re not allergic reactions, and the rules for allergies don’t apply.
You may hear people refer to an “MSG allergy,” but that’s incorrect. And allergists aren’t the ones to ask about your reactions to MSG.
If you have questions or comments, we’d love to hear from you. If you have hints for others on how to avoid exposure to MfG, send them along, too, and we’ll put them up on Facebook. Or you can reach us at firstname.lastname@example.org and follow us on Twitter @truthlabeling.
