Gastronomy
Gastronomy is the study of food and culture, with a particular focus on gourmet cuisine. One who is well versed in gastronomy is called a gastronome, while a gastronomist is one who unites theory and practice in the study of gastronomy.
Etymology
Etymologically, the word "gastronomy" is derived from Ancient Greek γαστήρ, gastér, "stomach", and νόμος, nómos "laws that govern", and therefore literally means "the art or law of regulating the stomach". The term is purposely all-encompassing: it subsumes all of cooking technique, nutritional facts, food science, and everything that has to do with palatability plus applications of taste and smell as human ingestion of foodstuffs goes.
Gastronomy involves discovering, tasting, experiencing, researching, understanding and writing about food preparation and the sensory qualities of human nutrition as a whole. It also studies how nutrition interfaces with the broader culture. Later on, the application of biological and chemical knowledge to cooking has become known as molecular gastronomy, yet gastronomy covers a much broader, interdisciplinary ground.
