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.
