Monosodium Glutamate (MSG)
You’ve probably heard of monosodium glutamate (MSG). You’ve likely eaten it, too. But MSG on its own was created by scientist Kikunae Ikeda.
He extracted glutamate from a broth so that the taste of that rich broth could be present in all sorts of foods.
However, consumers complained about MSG causing headaches, nausea, chest pain, numbness, and several other symptoms.
To see what was really going on, research was conducted to determine if there was a correlation between MSG and these symptoms.
In the end, there was no evidence that the symptoms were correlated to MSG.
Even so, if an individual consumes more than three grams of MSG on an empty stomach and they are sensitive to this substance, it is possible that these symptoms can occur.
Consuming three grams of MSG in this manner would be highly unusual, though.
