Disgust is a type of aversive reaction that involves withdrawing from a person or object with strong expressions of revulsion. It can also be defined as a revulsion response towards potential contamination. It is a universal, basic emotion that functions to help protect an organism from ingesting potentially harmful substances, thereby promoting disease avoidance.[2] It is one of the basic emotions and is typically associated with things that are regarded as unclean, inedible, infectious, gory or otherwise offensive.
