Superlist UK

Which supermarkets make healthy and sustainable the easiest choice in the UK?

Supermarkets influence to a large extent what their customers buy. This gives them the opportunity to make food habits healthier and more sustainable. With Superlist, Questionmark Foundation helps supermarkets to seize this opportunity.

Superlist is a multi-year research project that provides insight into what supermarkets are doing to make our food healthy and sustainable. Superlist started in 2019 in the Netherlands.

Superlist UK

Superlist UK is the first pilot outside of the Netherlands. For this pilot Questionmark will assess the four largest supermarket chains in the UK (in terms of market share): Tesco,  Sainsbury's, Asda and Morrissons (10%). For “health” we will look at the volume of High Fat Sugar Salt (HFSS) products in the promotions. For “sustainability” we will look at the share of meat promotions and the availability of relevant information on the provenance of meat products.

The assessment will lead to a short report with the main findings. The report will be published in two parts, health and sustainability. Data on assortment and promotions will be collected during a 6-week period, starting on August 24. During this period, all webshops will be visited in four data collection cycles.
