Brief Summary
Unhealthy diets significantly contribute to major preventable chronic diseases including type 2 diabetes, obesity, heart disease and stroke, which disproportionally impact racial/ethnic minority groups and those with lower income \[1-3\]. Although taxes and warning labels targeting sugar-sweetened beverages (SSB) have been successful at shifting behavior \[4-7\], there are many other ultra-processed food products that contribute to unhealthy diets \[8\]. What is less well-known is whether a suite of healthy food policies that are expanded to target a range of ultra-processed foods can shift dietary choices and intake in meaningful ways. Our research team's long-term goal is to identify and understand the degree to which combinations of healthy food policies can improve nutrition security and reduce nutrition-related diseases.

Outcome Measures
Primary Outcomes (1)
Average kcals purchased per participant per day from unhealthy ultra-processed food products that are targeted by our suite of healthy food policies
We will sum the number of kcals from ultra-processed food products purchased in the online grocery store and divide that by the number of people in the household and 7 days per week. We will then add that to the number of kcals from ultra-processed foods purchased from the online restaurant to calculate total kcals from ultra-processed foods purchased per study participant per day. We will also examine these outcomes separately in the grocery store and restaurant context.
Change between baseline and Weeks 2-4 (Aim 1) and Weeks 5-6 (Aim 3)
Secondary Outcomes (12)
Average sodium, saturated fat, and added sugars purchased per participant per day from unhealthy ultra-processed food products that are targeted by our suite of policies
Change between baseline and Weeks 2-4 (Aim 1) and Weeks 5-6 (Aim 3)
Average overall kcals, sodium, saturated fat, and added sugars from all foods purchased in the online grocery store and restaurant per participant per day
Change between baseline and Weeks 2-4 (Aim 1) and Weeks 5-6 (Aim 3)
Percentage of total dollars per order spent on products targeted by our suite of healthy food policies
Change between baseline and Weeks 2-4 (Aim 1) and Weeks 5-6 (Aim 3)
Total dollars spent on food and beverage products purchased outside of the study grocery store and restaurant
Baseline to Week 6
Total dollars spent on sugar sweetened beverages, candy, and fast food purchased outside of the study grocery store and restaurant
Baseline to Week 6
