Description
Genevieve Buckland and co-authors asked whether a city rule on food ads changed what households buy, in a 2026 study. In 2021 Bristol barred ads for foods high in fat, salt, and sugar on council-owned sites, mostly bus stops. It was the first city outside London to do so. The team used shop data from just over one thousand households, in Bristol and in control areas, over a span that covered the change.
The analysis compared buying after the rule with what buying would have been without it. No clear change showed up for energy, fat, sugar, or salt from the barred foods. Splits by household type also showed no clear shift. The authors report the null result plainly. A ban on one set of ad sites, on its own, did not move the weekly shop in a way the data could detect.
