  • 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 youre 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.
