September 29/Washington/Asian News International (ANI) -- A new study has revealed that the carbon dioxide in fizzy beverages sets off the same pain sensors in the nasal cavity as mustard and horseradish.
"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, an associate professor of neurobiology in the USC College of Letters, Arts and Sciences at the University of Southern California.
