About this study

In plain language

This study tests whether personalized online shopping messages can help people buy whole grains instead of refined grains. Some messages will include discounts that change based on what people buy. It is for Penn Medicine patients ages 45–70 with prediabetes (blood sugar above normal) or type 2 diabetes.

Only 2% of Americans meet the recommended levels of whole grain consumption, despite its association with reduced risk of type 2 diabetes. This study aims to assess if consumers with prediabetes or type 2 diabetes can be encouraged to switch from buying refined grain products to whole grain products when shopping for groceries online. The study will use personalized marketing strategies, with or without discounts which adjust based on purchasing behavior, to promote whole grain consumption.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
