We introduce a simple solution to help consumers manage choices between healthy and unhealthy food options: vice-virtue bundles. Vice-virtue bundles are item aggregates with varying proportions of both vice and virtue, holding overall quantity constant. Four studies compare choice and perceptions of differently composed vice-virtue bundles relative to one another and to pure vice and pure virtu...
