Don't blame your taste buds when your food loses it's flavor. Blame your stuffed up nose! Did you know that around 70% we actually taste comes from our sense of smell. Bitter, salty, sweet, and sour flavors are perceived by our taste buds. When you put food in your mouth, odor molecules from that food travel through the passage between your nose and mouth to olfactory receptor cells at the top of your nasal cavity, just beneath the brain and behind the bridge of the nose. If mucus in your nasal passages becomes too thick, air and odor molecules can't reach your olfactory receptor cells. Your brain receives no signal identifying the odor, and everything we eat tastes similar. Of all our senses, smell is most primal.

Great job. Very interesting to know taste buds are not the real reason food taste. Probably explains why everything tastes the same when you are sick.
ReplyDeleteI really like how you ladies explained your presentation and how you provided background information about taste and smell before the experiment to help the class understand the out come. It was also nice when you explained why you must use the water before you hold your nose. Great job!
