How does a stuffy nose affect our sense of taste??

sense of taste (sweet, salty, sour, bitter, umami) is not affected by sense of smell
however your nose, where you have a large number of olfactory neurons with receptors for many different chemicals. Foods like strawberries or chocolate contain many chemicals which dissolve in the air, and these volatile odors are detected by your olfactory neurons. So, in addition to tasting the sweetness of the sugar in chocolate or strawberries, you also smell the volatile odors associated with those foods. It's the smell and the taste together that give you the sensation of "chocolate" or "strawberry."

When your nose is plugged because of a cold, these volatile molecules don't have access to the olfactory neurons. So, you can't smell the wonderful aroma, even though the sweetness is still there.

Here is an experiment to convince yourself. Chop little pieces of potatos and apples. Then close your eyes, hold your nose and tell someone to give you random pieces of either potato or apple. Then try to guess what it is? Did you guess wrong? No problem, most people do.
