Cross-domain variety seeking in human food choice.

Adult Americans (n = 123) indicated which of a wide variety of soups, sodas, fruits and vegetables they had eaten in the last year. The number of different types consumed for each of these categories was correlated. These data yielded intercorrelations ranging from 0.10 to 0.60, indicating some cross-domain consistency in variety seeking. There were no significant correlations of variety of food selection in these food domains with age.
