Taste is the chief reason people choose the foods they eat. Taste is one of the sensations produced by the tongue when in response to certain substances such as food. The noticeable factor that makes people choose one food over another is its taste and this is natural. Human behavior concentrates on choosing the best possible food by discovering what is edible, what is not edible, and which combinations are good and which are not. Food that tastes good is appealing, even though foods that are observed to be tasty may differ generally from a person to another.
