In this investigation, learners gather information on various food items during a field trip to a local grocery store. In order to complete the lab study, learners read product labels, compare fat, sodium, and sugar contents of various food items, and then make judgments regarding the comparative "healthiness" of the available items. Learners record this information on a data form. Learners work with a partner and often employ the assistance of the deli and bakery manager, other learners, or shoppers. In follow-up/extension activities, learners use their data forms to assist them in developing sample diets (that would follow the nutritional recommendations for persons with high CD risk or for persons suffering from cardiovascular disease).
