Palatability versus healthiness as determinants of food preferences in young adults: a comparison of nomothetic and idiographic analytic approaches.
Past research on adults has found that the sensory appeal or taste of foods is a primary determiner of food consumption and how people think about food. The nomothetic nature of this research may have underestimated the impact of health considerations on food choice. This study compared 'nomothetic' and 'idiographic' modes of analysis in 1) determining the relative influence of palatability and perceived healthiness of foods, on preference for the food, and 2) assessing the relationship between palatability and evaluations of healthiness. Additionally, gender differences were examined in relation to within-person correlations between the concepts of preference, palatability and healthiness. Subjects (n = 139) rated 81 foods on preference, palatability and healthiness. Findings from both the idiographic and nomothetic analyses indicated that palatability rather than health considerations determined preferences in young adults. The within-person correlational analysis indicated a large number of persons, mostly female, who preferred unhealthy food. The sample was equally split in their evaluations of healthy food as palatable or not.
