Social class differences in food consumption refers to how the quantity and quality of food varies according to a person's social status or position in the social hierarchy.[1] Various disciplines, including social, psychological, nutritional, and public health sciences, have examined this topic. Social class can be examined according to defining factors — education, income, or occupational status — or subjective components, like perceived rank in society. The food represents a demarcation line for the elites, a "social marker", throughout the history of the humanity.[2]
Eating behavior is a highly affiliative act,[3] thus the food one eats is closely tied with one's social class throughout history.[4] In contemporary Western society, social class differences in food consumption follow a general pattern. Upper class groups consume foods that signify exclusivity and access to rare goods;[4][5] while lower class groups, on the other hand, consume foods that are readily available.
