Was I allergic? Is that even a thing? Why does no one else complain about this? Recently, though, I was relieved to find out that I am not crazy, and, apparently, I am not the only one this happens to.
According to research done at USC in , "The carbon dioxide in fizzy drinks triggers the same pain sensors in the nasal cavity as mustard and horseradish, though at a lower intensity.
This cell, which expresses a gene that serves as a general pain sensor, is the same type of cell that detects mustard. Who knew soda and a spicy condiment had so much in common? Those bubbles do cause some weird stuff to happen. Carbonated beverages are produced by dissolving carbon dioxide in liquid, typically under high pressure. Popping open a can or bottle of the liquid reduces that pressure, releasing the carbon dioxide in the form of bubbles.
Enzymes in the mouth convert the carbon dioxide into carbonic acid. It turns out the medication blocked the enzyme that converts carbon dioxide into carbonic acid. Still, popular belief continued to hold that the bubbles were primarily responsible. To settle the debate, scientists at the Monell Chemical Senses Center in Philadelphia took advantage of the inability of bubbles to form above a certain pressure level.
They saw no difference in the bite ratings reported in the two conditions. But the bubbles may have still influenced that perception. Earlier studies have shown that light touch can soothe pain — much like how rubbing a mosquito bite can relieve itching -- so the researchers expected the bubbles to suppress the sting of carbonation. A study in the journal Science found that carbonation trips cells in the tongue that detect sourness.
Researchers wanted to find which cells are responsible for the painful sensation that comes with drinking soda. They poured carbonated saline onto a dish of nerve cells taken from the nose and mouth.
