The
body responds to soda fizz just as it does to mustard and horseradish,
according to new research at the University of Southern California.
“Carbonation
evokes two distinct sensations. It makes things sour and it also makes
them burn. We have all felt that noxious tingling sensation when soda
goes down your throat too fast,” said Emily Liman, whose research has
been published in the Journal of Neuroscience.

A system of nerves is what creates these pain sensations in the skin, nose and mouth.
“What
we did not know was which cells and which molecules within those cells
are responsible for the painful sensation we experience when we drink a
carbonated soda,” said Liman, an associate professor of neurobiology in
the USC College of Letters, Arts and Sciences.

But if carbonated beverages are linked to pain circuits, why are they popular?
There are studies more than 100 years old that show carbonations reduces the growth of bacteria.
"Or it may be a macho thing," Liman speculates.
