For years I have been teaching that there are various areas of your tongue that are sensitive to specific tastes: sweet, salty, bitter, sour ( and most recently umami which senses MSG). As I was researching to once again teach the unit, I stumbled across numerous articles that basically said that everyone for years has accepted this theory of a “tongue map” without questioning the science behind it. It turns out that research from as long ago as 1974 debunked the myth, but it continues to be taught and displayed in textbooks!
So, to those of you who could never quite understand why your taste buds didn’t fit the “test” with different solutions, you are vindicated! Everyone IS ABLE to taste all types of tastes everywhere on the tongue, though some areas may have more receptors for specific types of tastes. Then there is the whole issue of taste buds and whether or not you are a “super taster,” but that we will save for another time.
Here is an article from LiveScience magazine that cites some research, and is an easy read.
Keep on tasting!
