Since 2018 Cancer Research UK, British Heart Foundation and Diabetes UK have partnered with the major UK retailer Tesco with the aim of ‘Helping you to live healthier’. In March 2022, the three charities independently commissioned YouGov to conduct 'Trolley Trends' research to explore attitudes and behaviours around healthy eating and food shopping. Tesco provided a sample of customer Clubcard data which also allowed YouGov to explore actual purchasing behaviours.
