All About Taste Buds
Glenn was wrong! I cannot believe it. He was absolutely wrong.
Here’s what I wrote in my book:
When Glenn returned, he explained how different taste buds on your tongue sense different flavors: sweet is detected at the tip of the tongue, sour on the sides, etc. I had a pickle in my lunch, and Georgie had a hunk of fudge, so I tested my taste buds by touching pieces of them to various parts of my tongue. As usual, Glenn was right. If you want to try this yourself, I put a taste bud diagram of the tongue on my website.
But when I started to write this webpage, I did some research. The tongue does NOT have different taste buds in different places. Here’s what I found online:
The notion that the tongue is mapped into four areas—sweet, sour, salty and bitter—is wrong. There are five basic tastes identified so far, and the entire tongue can sense all of these tastes more or less equally.
I think when we tested our taste buds at school, we sort of wanted to believe…so maybe we weren’t good testers. If you want, you can try it at home. See if you can use your own tongue to prove that the old diagram is wrong.
Tell me what you find out.
(P.S.—Glenn is not wrong very often.)
