Your phone has changed the way you eat

Young people's food environments no longer live in supermarkets and school canteens. They live in pockets: shaped by delivery apps, social media, and algorithms designed to sell, not to nourish. This is the part of the food system most of us can't see.

Stephanie Partridge has spent her career studying how digital and physical environments shape what adolescents eat and how healthy they grow up to be.

Her research does something unusual: it invites young people to help redesign the system. Because healthier futures don't get built without the people who have to live in them.
