Class steward is Patient Care
Food is a role of material. Food is anything that is ingested by humans to address hunger and provide nutrition to the body. Food is often combined into dishes, which are combined into full meals. Since the Material_relationship class can express this combination there are little additional properties needed in the food class. There is only one classifier attribute that seem to be relevant and special for food. We call that classifier "preference", which is described below.
The food preference describes the "style" and properties of the food that is selected mainly to meet the preference and customs of the recipient of the food. The term "preference" was selected to express that this property of food meets a preference of the consumer, not in order to limit this attribute to describe only the preferred style of food but not the actual style. The following concept repertoire is defined:
Table 40: Preferences, or "styles" of food Concept Implies Code Definition non-vegetarian NVEG Supposedly every reasonable food is permitted. no beef NVEG NBEF Everything but beef (e.g., a hindu will absolutely not eat beaf.) no pork NVEG NPRK Everything but pork (e.g., muslims and jews) kosher NPRK KOSH Prepared after the traditional jewish rules no beef and no pork non-veg.

OpenIssue: Should this be a subtype instead of a role relationship?
