Smell and taste are linked in that a person's brain merges messages about taste and smell, permitting a person to detect the flavor of a food, explains BrainFacts.org. When an odor and taste are experienced together, a person makes an association between the two sensory experiences, so that the smell of a food influences its taste, and the taste of a food influences its smell, notes Scientific American. When a person is unable to smell a food, he may discover that the food tastes different. In fact, the food has the same taste, but a person is not able to perceive the food's flavor because his brain is not receiving any olfactory messages, according to BrainFacts.org.
