So the other day I found myself eating broccoli and liking it, I had to stop and wonder where
-
did I go wrong in life? What happened to my tastebuds?
-
Hey guys, Julia here for DNews.
-
Right now, there are thousands of tastebuds on your tongue, some estimates say as many
-
as 10,000. And no you don’t have specific areas of your tongue for certain flavors,
-
the taste buds are all kind of mixed together.
-
but when you look at your tongue, those little bumps are little clumps of taste buds,
-
which each contain 50-100 taste cells, kind of like a head of broccoli.
-
One study got up close and personal with these miniscule mysteries. Tastebuds look kind of
-
like little bulbs, little flowers, with receptor cells looking like the petals surrounded by
-
blood cells which in turn is surrounded by collagen.
-
These taste cells take chemical signals from the food you eat and send it to taste centers
-
in your brain. Seriously, there’s a place in your brain just for tasting called the
-
Gustatory cortex.
-
Speaking of broccoli though, like when I was little I hated broccoli, like hated it. Now
-
So anyways, have my taste buds changed as I grew up? Well yeah, kind of. It’s no secret
-
kids like sweet things. But maybe it’s biology. One study published in the journal Physiology
-
Behavior, found that growing bones release hormones that cause children to crave the
-
sweets. That way their growing body get the energy it needs. The researchers also found
-
that that in people whose bones stopped growing, they had less of those hormones. So maybe
-
that’s why adults find overly sweet things sickening and prefer other flavors like delicious
-
bitter broccoli.
-
As for your actual taste buds, well the cells in your tastebuds don't last for long, they
-
change all the time. The average lifespan is anywhere from a few days to a month.
-
But a lot, I mean a lot of things can affect your sense of taste. From, temperature, to
-
altitude to music.
-
That Gustatory cortex I mentioned takes in information from a lot of different sources
-
from your other senses.
-
And memory affects taste too. There’s a thing called conditioned taste aversion or
-
CTA. Most of us have experienced this, for example my sister hates buffalo chicken dip,
-
I mean hates it, because a few years ago she ate it around the same time she got a nasty
-
stomach flu. So now a circuit in her amygdala is like, GIRL DO NOT EAT THAT DIP, YOU WILL
-
GET SICK. And a study published in the Journal of Neuroscience found that that negative associate
-
is particularly strong if you’re in the same place as that bad experience.
-
Not to get all evolutionary psychology on you, but that makes sense. If our ancestors
-
wandering about savannah came across some bad berries, they’d be more likely to survive
-
if their brain associated that place and berry with throwing up or something so they wouldn’t
-
eat it again.
-
but on the other hand, good experiences might make food taste better, so if you want to
-
one day get your kid to like vegetables, make it fun! Like put broccoli on top of mashed
-
potato mountains so it looks like a little landscape.. okay yeah you know what… I don’t
-
think you can make vegetables fun.
-
So no, that whole your taste buds change every 7 years is a bit of wives tale. Your taste
-
buds change all the time, and a lot of things affect the how something actually tastes.
-
To learn more about how music can make you taste things differently, check out this great
-
video from our friends over at BritLab, it’s blew my mind, go watch it, i really recommend
-
it.
