Do an apple, potato, and onion all taste the same if you eat them with your nose plugged?

It is frequently quoted that upwards of 80% of our taste is made up by smell. So if you plug your nose and cover your eyes, the taste between an apple and onion should be indistinguishable. All potato chip flavors taste the same.

Possibly.

Explanation:

d they all are treatable but they never completely go away
