Sensory Dysfunction | Overview


Why are smell and taste important?

Your senses of smell and taste let you fully enjoy the scents and flavors of foods and drinks. These senses also help protect you from food poisoning and warn you of dangers such as fire, polluted air and poisonous chemicals.

Is there a difference between taste and flavor?

Yes. The basic tastes are salty, sweet, bitter and sour. Flavor involves both taste and smell. For example, because a person is able to smell a chocolate bar while eating it, the chocolate not only tastes sweet but also has the flavor of chocolate. The flavor of chocolate candy might not be as good if you couldn’t smell it and taste it at the same time.
