ELI5: Why does everything taste a whole lot worse when you're sick?

Your nose plays as big a role in taste if not bigger than your tongue. Bite into an apple with your nose plugged and the aroma from the food cannot travel through your nasal cavity. Same thing applies when you are sick, your nose is stuffed up and scent cannot be converted to flavor.
