Outcome Measures

Primary Outcomes (1)

  • Food Waste Volume

    Food waste volume will be measured in grams using a study-provided food scale and waste log. Participants are asked to weigh discarded food and log the weight in a food waste tracking notebook for a period of 1 week prior to randomization at Baseline, and again for a period of 1 week at 10 weeks post-randomization. The outcome measure will use the difference in total volume of food waste between the two time points.

    Change from Baseline to 10 weeks post-randomization

Study Arms (2)

Nourish intervention then no intervention

EXPERIMENTAL

Subjects first participate in 9 weeks of weekly cooking classes, then no intervention for 9 weeks.

Behavioral: Nourish intervention then no intervention

no intervention then nourish intervention

EXPERIMENTAL

Subjects receive no intervention for 9 weeks, then participate in 9 weeks of weekly cooking classes.

Behavioral: no intervention then Nourish intervention

Interventions

no intervention then Nourish interventionBEHAVIORAL

Participants will receive no intervention for 9 weeks. After 9 weeks, they crossover into the Nourish Intervention group where they will attend a weekly in-person class with brief instructional video clips, hands-on cooking and tasting experiences. Participants will work individually and as part of small groups during instructional sessions. At the end of each class, participants will receive a grocery bundle and a kitchen gadget that serves both as an incentive and implementation support to promote improved cooking frequency and confidence. Participants will be asked to post photos of what they made with their groceries to an instant messaging software (GroupMe application) and be encouraged to engage with fellow classmates on GroupMe to encourage social support of cooking.
