Up to eighty percent of taste comes
not from our taste buds,but from our sense of smell.Taste buds allow us to identify bitter,salty,sweet,and sour flavors.but we depend on the smell of foods to give us most of our sense of flavor.So withour smelling the aroma of a food,it is difficult to distinguish one flavor from another. (Licidentally,this is why food loses its flavor when you have a stuffed-up nose)
