Why can’t we taste anything when we plug our nose but when we unplug it the taste is just normal again, even after swallowing
In: Biology
Our sense of taste is extremely limited. Sweet, sour, salty, bitter, umami. That’s all. No further nuance. What we interpret as the “taste” of food is really mostly its smell. That’s where we can distinguish thousands of compounds. So, if you block your nose, you miss out on most of what our brain usually considers “taste”.
Scent is a major component of taste. Your brain uses both pieces of information — smell and taste — to interpret foods.
