Dietary trigger lists for tics, migraines, and hyperactivity often include the flavor enhancer MSG (monosodium glutamate). Unfortunately, as this article explains, the additive is difficult to identify by ingredient lists, not to mention when eating out.
At the end of this page, we link to a testimonial of how certain foods, MSG, and other food additives affected an adult in Germany who suffered from Tourette syndrome. The fellow said in part:
“I have a particular problem with monosodium glutamate (MSG) in Chinese and other food. It worsens my motor tics and leads to more spasms in the range of shoulder, neck and upper arms.”
We share an excellent article that explains the hidden sources of MSG, and lists the shocking number of terms that can be used to represent MSG and keep it “hidden.” See below.
