A simple grocery cart trick may curb childhood obesity
NCT ID NCT07806721
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
This trial tests whether pre-filling online grocery carts with healthy recipe ingredients can help parents with obesity buy and serve more nutritious foods to their young children. Parents of 2-to-5-year-olds receive weekly recipe packets, and some also get carts pre-stocked with those ingredients. Researchers compare grocery purchases and children's eating habits over six months to see if this nudge improves diet quality.
