For example, anorexia and bulimia nervosa are more prevalent in industrialized societies, where there is an overabundance of food and where attractiveness in women is linked with being thin, than in agriculturally based societies. Immigrants from cultures in which anorexia nervosa is rare are more likely to develop the illness as they assimilate the ideals of a thin body appearance.
