Groceries will be delivered to participants' homes or picked up at a convenient location. The dietitian/nutrition interventionist will provide brief educational content at the time of food delivery. Orders will be placed via phone or through virtual counseling sessions. During the remainder of the study (months 4-12), participants will be asked to apply what they learned without the provision of groceries.
Participants will receive a monthly stipend over a 3 month period and some basic information about healthy eating. The stipend is not restricted to foods. During the remainder of the study (months 4-12), participants will be asked to continue their typical shopping without the provision of the monthly stipend.
