More about fun facts

During my today's journey in finding fun facts blog or sites, I found this interesting article titled, Why does orange juice tastes so bad after brushing your teeth ?

It's a question you may never have asked, but if you've ever brushed your teeth before you've had a glass of juice, you'll know why we had to seek professional advice.

David Cannell is the scientific spokesperson for Questacon, "It's because of a certain ingredient in toothpaste called sodium laurel sulfate. It actually blocks sweet sensors. All the other taste bud cells in your mouth are firing away nicely, but the receptors which pick up the sweet sensors are not working anymore. Not only does it block the sweet sensors, it enhances the sour and bitter, so you get this massive influx of sour and bitter taste coming through the mouth."

David says tastebuds are a very interesting part of the body, "They're the little bumps on the top of your tongue. They look like a tiny onion, if you look at it with a high powered microscope. Each tastebud, which we have about ten thousand of, has about fifty different taste cells."

"The tastebud itself goes through such a heavy process of tasting things left, right and centre, it gets too much for them. They actually die after about two weeks. But they generally grow back, but they don't always grow back. As you get older and older, your tastebuds do generally die off. You can be left with only two or three thousand."

"Kids have incredible taste sensitivity", David explains, "something that is really quite strong to taste they might consider completely disgusting. When you grow old, you get used to it." David laughs, "I think the message in here is not to feed children vegetables at the dinner table!"

"Scientists aren't sure why tastebuds do grow back, and why they don't grow back. But there are some things that will affect your tastebuds not growing back that will dull your taste sensitivity. Things like smoking", David Cannell.
