It could be argued that dance has its origins in emotions. Movement (dance) coming from the need for survival (Sheet Johnstone 1966). The need to move towards food, towards mother, away from danger, predator, fire, etc. Similarly food could be seen as the stuff that satisfies the need for nourishment.
Food, however, has ceased to be simply nourishment. Think of all the cooking shows, and kinds of food that people eat that have little or no nutritional value. Food as entertainment and enjoyment. Also the food geeks who research how to do different processes and aren’t directly interested in food as nourishment. Think of Nathan Myhrvold, Microsoft’s first CTO, who made that huge cookbook. Food as a means of epistemology.
So why is dance still so heavily associated with movement’s origin, emotion, and seen less as a means of epistemology?
