Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In behavioral economics, the default option refers to the option a consumer selects if no active choice is made. This study aims to determine whether the use of a default prefilled online grocery shopping cart results in the purchase of healthier food items in individuals with food insecurity, compared to nutrition education. The default approach, a non-monetary intervention that manipulates choice architecture, improves food choice behaviors in individuals facing significant financial constraints. The intervention is potentially broadly scalable via online platforms.
It was hypothesized that the default option effectively increases the nutritional quality of foods purchased online, compared to nutrition education.
Fifty participants recruited from food pantries in New York in 2018 were randomized to: (1) review nutrition information before selecting groceries for a week using a local grocery store's online shopping and delivery service (n = 23) or (2) modify a default prefilled online shopping cart containing groceries that meet nutritional guidelines according to their personal preferences (n = 27).
Primary outcome measures capture the nutritional quality of groceries purchased. Our primary nutritional outcomes include servings of whole grains fruits and vegetables, fiber, daily calories, fat, saturated fat, sodium and cholesterol content.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Default
Participants in the default condition were presented with a pre-filled online shopping cart containing a combination of groceries that meet macro- and micronutrient requirements for their gender and age, and told that they are free to delete, add, and exchange any item they wish to finalize their selections.
Default Option While Online Grocery Shopping
The "default option" is a behavioral economics construct that refers to the option a consumer selects if no active choice is made (e.g. opt-out 401K plans, which significantly increase enrollment, compared to active sign up). Participants in the default condition were presented with a prefilled online shopping cart containing groceries that met nutritional requirements based on participants' gender and age.
Nutrition Education
Participants in the nutrition education condition were instructed to read a brief education brochure before online grocery shopping.
Nutrition Education
The nutrition education materials were adapted from materials currently utilized by the New York State Office of Temporary and Disability Assistance ("Eat Smart New York").
