Craving a Fizzy Taste?

Many of you have no doubt craved a fizzy soft drink, but perhaps instead of craving the cola taste you were craving the fizzy taste? That may sound strange, but scientists recently discovered that carbonation actually has a flavor and that our taste buds can, in fact, taste the carbon dioxide that gives drinks their fizz. Researchers studying mice, which have a similar sense of taste as humans, were able to determine that carbonation tastes sour. By eliminating a single gene, mice had their ability to taste sour things turned off and no longer responded to carbonation. The gene that was turned off encodes an enzyme that breaks down carbon dioxide and water into bicarbonate and protons. The protons, which are essentially acid, are what the sour-sensitive taste cells appear to sense. For more information on the study, see Science Daily.

    Whenever I crave something fizzy, I simply stick an electrical cord in my mouth. I hear it’s much better for you than soda pop.

    Or maybe we’re just craving the massive belch that follows consumption of mass quantities of soda pop!
