This clinical trial tests the feasibility, acceptability and effect of an optimal defaults grocery shopping intervention to promote healthy diets for pediatric cancer survivors and their families. Pediatric cancer survivors are a growing population who are at an increased risk of developing chronic conditions and treatment-related complications. Poor nutritional intake can significantly worsen chronic health conditions experienced by survivors. Children who have poorer nutrition post-treatment are at greater risk for cancer recurrence. Interventions that effectively support families in obtaining and consuming healthier food and improve dietary intake are poised to improve developmental outcomes among pediatric cancer survivors. One promising way to impact the family diet is by targeting food purchasing. Optimal defaults, or making the healthy choice the automatic choice, is a specific nudge strategy that may be a feasible, acceptable and effective way to promote healthier food purchasing and dietary intake among pediatric cancer survivors and their families.

UP to 4 weeks
Families (cancer survivor and their parent/legal guardian) shop for groceries as normal for 2 weeks, using Instacart for at least 75% of shopping, and provide receipts for this shopping. At the end of Week 2, families meet with study staff to address any grocery shopping questions. Families receive 4 recipes per week for 2 weeks while continuing to record their grocery shopping. Recipe packets include 3 main meal recipes as well as an idea of an additional breakfast/lunch/snack that can be made with leftovers from the main meal recipes, nutritional characteristics of the recipes and some simple nutrition education tips. Recipe options can be assigned depending on families' dietary restrictions and food preferences. At the end of Week 4, families meet with study staff to address any grocery shopping questions.

Families (cancer survivor and their parent/legal guardian) shop for groceries as normal for 2 weeks, using Instacart for at least 75% of shopping, and provide receipts for this shopping. At the end of Week 2, families meet with study staff to address any grocery shopping questions. Families receive 4 recipes per week for 2 weeks, continue to record their grocery shopping, and have their online Instacart grocery carts prefilled with the ingredients needed to make the recipes. Families may make changes to their carts as they like. Recipe packets include 3 main meal recipes as well as an idea of an additional breakfast/lunch/snack that can be made with leftovers from the main meal recipes, nutritional characteristics of the recipes and some simple nutrition education tips. Recipe options can be assigned depending on families' dietary restrictions and food preferences. At the end of Week 4, families meet with study staff to address any grocery shopping concerns
