This study examines how sociodemographic characteristics of a household's main meal planner affect use of nutritional information concerning ingredients, health benefits, calories, sodium, vitamins/minerals, fiber, fat, cholesterol, and sugar content on food packages. Results generally suggest that well-educated, female main meal planners are more likely to use various types of nutritional information than others. Main meal planners who place more importance on nutrition but less importance on taste and those who have a higher perception of the healthfulness of their diet are more likely to use nutritional information on packages than others. Household size, race, employment status, urbanization, region, age, and income are also significant factors.
