Journal Article
To examine whether four pre-selected front-of-pack nutrition labels improve food purchases in real-life grocery shopping settings, the authors put 1.9 million labels on 1,266 food products in four categories in 60 supermarkets and analyzed the nutritional quality of 1,668,301 purchases using the FSA nutrient profiling score. Effect sizes were 17 times smaller on average than those found in comparable laboratory studies.
